However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10 speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle, and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance, because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off-the-line. Even though this Ford 10 speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R80 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003cbr\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003cbr\u003eReverse – 4.87\u003c\/p\u003e\n\u003cp\u003eAs shown above this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands.

However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10 speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle, and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance, because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off-the-line. Even though this Ford 10 speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R80 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003cbr\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003cbr\u003eReverse – 4.87\u003c\/p\u003e\n\u003cp\u003eAs shown above this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands.

The course media is common in most filters (orange filter paper), the fine media filtration (White paper) is the newer material. There is a thermal plate inside the filter that separates the course and fine media. When the oil is colder (higher viscosity) at startup, The fluid will flow through both the fine and course filter media.\u003c\/p\u003e\n\u003cp\u003eAs the fluid heats up (less viscosity) , the thermal plate will bend and restrict the coarse media section; directing most of the fluid through the fine media.

The 4L65E shares the same exterior parts but has stronger internals, such as 5 pinion planets compared to 4 in the 4L60E. These also can carry several different input shafts depending on which version you have. The early 4L60Es had a 298mm input shaft for non-LS platforms while the later LS models utilized a 300mm one. The later 4L70E also utilized an input speed signal on the input shaft.\u003c\/p\u003e\n\u003cp\u003eAn updated 4L60E, the \u003cstrong\u003e4L65E\u003c\/strong\u003e (RPO M32), was phased in the 2001 model year when coupled behind the 6.0 Vortec. Five-pinion front and rear planetaries, along with an additional 3-4 clutch allowing 7 clutches in the input housing and induction-hardened input shaft assembly, were improved to withstand up to 380 ft-lbs (515 N-m) of torque.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Category 1 Kit\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis Category 1 SunCoast 4L60\/65\/70E kit has everything you need for a successful high performance rebuild.

This servo has an impressive 18% more apply area than the OE \"Corvette\" servo and features a dual seal design, ensuring a more positive band apply\/release and eliminating cross-leaks within the bore.\u003c\/p\u003e\n\u003cp\u003eThis new servo is manufactured from billet aluminum and features a chromoly steel apply pin that has added seals to reduce leakage of 3rd gear pressure. This is the fastest band release in the industry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Billet Pump Rotor\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003eThe 700R4\/4L60\/65\/70E platforms are notorious for pump cavitation at higher rpms. A typical solution would be to increase pump vanes to allow more fluid volume to be dispense. \u003c\/p\u003e\n\u003cp\u003eThe problem lies that as I increase pump vanes the material between vanes is significantly less and less. With cast material this can be a critical failing point. In this Suncoast category kit we are replacing the factory cast piece that is also know for premature failure with a full precision machined billet 13 vane pump rotor. \u003c\/p\u003e\n\u003cp\u003eThis pump rotor not only increases fluid volume but adds the reliability and strength needed in a high performance build.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Apply Band\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 4L60\/65\/70E transmissions utilize an apply band when shifting from 1st to 2nd and again when shifting from 3rd to 4th. This band is wrapped around the reverse input drum that sits directly behind the front pump assembly.\u003c\/p\u003e\n\u003cp\u003eThis band is known to be the weakest link in this unit, a problem that becomes even more prominent when you start deleting torque management or adding power modifications.

The 4L80E was heavily based on the TH400 first produced in October 1963, adding electronic controls and an overdriven fourth gear. The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing Things Up\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSunCoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results. These imidized plastic checkballs are not available through the original manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUpgraded sprag\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe intermediate sprag on the 4L80E's typically come with a 16 element intermediate sprag assembly.

The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing Things Up\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSunCoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing things up\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSuncoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results.

The 4L80E's were optioned only in Chevrolet\/GMC pickups, 2500 Suburbans, vans, and commercial vehicles, and the Hummer H1.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing Things Up\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSunCoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results.

Imbalance of torque converter clutch apply oil through the front stator support bushing contributes to this complaint. A journal clearance of .002\" or more will generate sufficient leakage to cause lockup clutch slippage, causing the transmission to stay in third gear. Sonnax front stator support bushing 34016-W is designed to reduce leakage by minimizing journal clearance and also increasing journal length.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSealing Things Up\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSunCoast always upgrades the check balls in all of our new 4L80E and 4L85E transmission rebuilds.

The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel checkballs are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Similar imidized plastic balls have been used on some original equipment late model valve bodies with excellent results. These imidized plastic checkballs are not available through the original manufacturer.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUpgraded sprag\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe intermediate sprag on the 4L80E's typically come with a 16 element intermediate sprag assembly.

Increased stall is usually needed in applications where a larger turbo or turbos have been installed and more RPM is required to get the turbo on boost while on the brakes (brake boosting).\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eStronger Chromoly steel turbine and impeller hub for additional strength and reliability\u003c\/li\u003e\n\u003cli\u003eCustom upgraded sprag cartridge with over twice the holding capacity\u003c\/li\u003e\n\u003cli\u003eThree friction surfaces more than triple surface area\u003c\/li\u003e\n\u003cli\u003eWoven Carbon Fiber clutch material\u003c\/li\u003e\n\u003cli\u003eFurnace Brazed Turbine and Pump Fins\u003c\/li\u003e\n\u003cli\u003eTorrington Roller Bearing Construction\u003c\/li\u003e\n\u003cli\u003eTig Welded Pump and Turbine Fins\u003c\/li\u003e\n\u003cli\u003eCustom CNC'd Billet 4140 billet cover\u003c\/li\u003e\n\u003cli\u003eCustom Billet Stator Cap\u003c\/li\u003e\n\u003cli\u003eCustom Billet Apply Piston\u003c\/li\u003e\n\u003cli\u003eCustom Heat Treated Steel Hub\u003c\/li\u003e\n\u003cli\u003e2 year unlimited mileage warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":49129454338267,"sku":"SC-6L80E-CAT5-R","price":5895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198647705.jpg?v=1786544283"},{"product_id":"suncoast-4r70w-4r75w-category-0-rebuild-kit","title":"SUNCOAST 4R70W\/4R75W CATEGORY 0 REBUILD KIT","description":"\u003cp\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRaybestos Clutch Module With GPZ Direct Clutch Pack® Module\u003c\/li\u003e\n\u003cli\u003eRaybestos Upgraded Steel Clutch Module\u003c\/li\u003e\n\u003cli\u003eRaybestos Upgraded Pro Series Overdrive Band\u003c\/li\u003e\n\u003cli\u003eNew Low\/Reverse Band\u003c\/li\u003e\n\u003cli\u003eNew Molded Piston Kit\u003c\/li\u003e\n\u003cli\u003eNew Bushing Kit\u003c\/li\u003e\n\u003cli\u003eNew Thrust Washer Kit\u003c\/li\u003e\n\u003cli\u003eNew Filter\u003c\/li\u003e\n\u003cli\u003eNew Overhaul Kit\u003c\/li\u003e\n\u003cli\u003eAll Gaskets and Seals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eThe 4R70W\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn 1962 Ford began working on a new type of automatic transmission that would emphasize fuel economy and drivability. The new transmission was built around the Ravigneaux Planetary Gearset of the \"X\" transmissions. Where many transmissions had a fourth gear added on as an afterthought, Ford's new transmission was designed with a fourth gear integrated into the gearset. Because it was based on the \"X\" transmissions, its gear ratios from 1-3 were the same with the fourth being 0.67:1. The transmission featured a split-torque application for third gear as well as a lockup in the torque converter. The XT-LOD was initially abandoned in 1966 but design began again in 1974 as a result of rising gas prices. The project was shelved with a design that lacked a damper in the torque converter but after the project was revisited a damper ultimately made its way into the final design. The transmission was introduced when Ford started to downsize its full-size line in 1979. Initially called XT-LOD (Extension Lock-Up Overdrive) its name was changed when revisited in 1974 to FIOD (Ford Integrated Overdrive) and then to its final name in 1979, the Ford AOD transmission.\u003c\/p\u003e\n\u003cp\u003eA revised version of the AOD-E Transmission was released in 1993 with the Lincoln Mark VIII. Unlike the AOD-E, both 1st and 2nd gear ratios in the 4R70-W are numerically higher, giving the transmission a better mechanical advantage and in turn, better take-off acceleration, slightly lower fuel consumption, and designed for better gearset strength. On vehicles powered by the 5.4L V8, a stronger gearset is used than in normal duty 4R70Ws.

In fact, a Ford document stated that the 2003 \"Expedition's 4R70W transmission is rated to handle up to 506 foot-pounds of torque, which provides a large performance cushion beyond the peak torque rating of Expedition's largest available engine.\"\u003csup id=\"cite_ref-1\" class=\"reference\"\u003e\u003c\/sup\u003e It is more plausible that the number indicates the torque handling capability in N-m, as 506lb-ft converts to 686 N-m which could be rounded to 700 N-m.

The new transmission was built around the Ravigneaux Planetary Gearset of the \"X\" transmissions. Where many transmissions had a fourth gear added on as an afterthought, Ford's new transmission was designed with a fourth gear integrated into the gearset. Because it was based on the \"X\" transmissions, its gear ratios from 1-3 were the same with the fourth being 0.67:1. The transmission featured a split-torque application for third gear as well as a lockup in the torque converter. The XT-LOD was initially abandoned in 1966 but design began again in 1974 as a result of rising gas prices. The project was shelved with a design that lacked a damper in the torque converter but after the project was revisited a damper ultimately made its way into the final design. The transmission was introduced when Ford started to downsize its full-size line in 1979. Initially called XT-LOD (Extension Lock-Up Overdrive) its name was changed when revisited in 1974 to FIOD (Ford Integrated Overdrive) and then to its final name in 1979, the Ford AOD transmission.\u003c\/p\u003e\n\u003cp\u003eA revised version of the AOD-E Transmission was released in 1993 with the Lincoln Mark VIII. Unlike the AOD-E, both 1st and 2nd gear ratios in the 4R70-W are numerically higher, giving the transmission a better mechanical advantage and in turn, better take-off acceleration, slightly lower fuel consumption, and designed for better gearset strength. On vehicles powered by the 5.4L V8, a stronger gearset is used than in normal duty 4R70Ws. In 1998, due to durability concerns, the intermediate one-way roller clutch was replaced with a mechanical diode providing extra holding capacity and longer service.\u003c\/p\u003e\n\u003cp\u003eWhile there is some speculation that the 70 can be multiplied by 10 to indicate the ft-lb of torque this transmission is capable of handling including torque converter multiplication, (i.e. 700 ft-lb of torque), there is no reliable source indicating this. In fact, a Ford document stated that the 2003 \"Expedition's 4R70W transmission is rated to handle up to 506 foot-pounds of torque, which provides a large performance cushion beyond the peak torque rating of Expedition's largest available engine.\"\u003csup id=\"cite_ref-1\" class=\"reference\"\u003e\u003c\/sup\u003e It is more plausible that the number indicates the torque handling capability in N-m, as 506lb-ft converts to 686 N-m which could be rounded to 700 N-m. The \"70\" may also refer to the transmission's torque capacity after torque converter multiplication which occurs at low rpm's when the torque converter is more \"elastic\". 4R70W indicates 4 gears, Rear wheel drive and Wider gear ratio compared to the AODE.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Clutches\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRaybestos Powertrain GPZ friction plates greatly increase transmission performance and durability.

However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10-speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off the line. Even though this Ford 10-speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quick\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R80 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003c\/td\u003e\n\u003ctd\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eAs shown above, this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands.

However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10-speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off the line. Even though this Ford 10-speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R80 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003cbr\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003cbr\u003eReverse – 4.87\u003c\/p\u003e\n\u003cp\u003eAs shown above, this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands. This allows the use of much larger camshafts in a naturally aspirated application. If you are looking into going to a forced induction setup, this shift recovery allows for larger turbo and AR housing for max performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNewly Designed Thermal Flow Control Filter\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 10R80 transmission has a newly designed filter that has two types of media, fine and course (medium). The course medium is common in most filters (orange filter paper), and the fine medium filtration (White paper) is the newer material. There is a thermal plate inside the filter that separates the course and fine media. When the oil is colder (higher viscosity) at startup, the fluid will flow through both the fine and course filter media.\u003c\/p\u003e\n\u003cp\u003eAs the fluid heats up (less viscosity), the thermal plate will bend and restrict the coarse media section, directing most of the fluid through the fine media and, therefore, catching more of the finer debris once the fluid is heated giving it a far superior filtration system.\u003c\/p\u003e\n\u003cp\u003eThis new SunCoast 10R80 rebuild kit comes with a new factory filter to ensure zero flow issues.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Clutches \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRaybestos Powertrain GPZ friction plates greatly increase transmission performance and durability.

This is not an approach that is simply bumping in more line pressure in hopes of ascertaining more clamping force; it’s a multi-faceted approach addressing several key issues when exposing these units to more demanding driving environments. These range from heavy towing and hauling to street racing and drag racing. \u003c\/p\u003e\n\u003cp\u003eThe factory 10R80 transmission lock-up circuit is an impressive one, in that it can make converter lockup seem somewhat uneventful. The refinement in its engagement is definitely next-level to what we have seen in the past. As nice as this feels in reference to the NVH (Noise Vibration Harshness), when we start introducing situations where the load demands are testing the limits or outside what the vehicle was initially designed for, it can become a huge problem. \u003c\/p\u003e\n\u003cp\u003eIn our SunCoast 10R80 Pro Loc Valve Body we are specifically looking to decrease the time from initial lock-up apply to zero turbine slip. In doing this, we are changing the lockup circuit by replacing the torque converter clutch (TCC) valve in order to increase lockup holding apply fluid pressure. The lockup oil transition time is also improved by modifying critical oiling circuits for the fluid to reach the TCC clutch, resulting in quicker apply time, and therefore, reducing TCC clutch degradation. By reducing degradation per apply cycle, we are allowing for improved reliability and performance.\u003c\/p\u003e\n\u003cp\u003e(\u003cstrong\u003e\u003cem\u003eNOTE:\u003c\/em\u003e\u003c\/strong\u003e For maximum results in power levels exceeding 800HP, it is highly recommended that the TCC apply offset be changed in the factory file calibration)\u003c\/p\u003e\n\u003cp\u003eThe next facet we address is the lube circuit. The lube circuit on the 10R80 transmission is responsible for supplying oil to the planets, clutches, bushings, etc. From the factory, the lube circuit oil is dispersed throughout the transmission as low as 6 PSI. Under normal load demands, this is perfectly acceptable. In more stressful and demanding situations, an increase in lubrication to clutches, steels, planets is ideal for removing heat and dealing with the increased demands. \u003c\/p\u003e\n\u003cp\u003eIn our 10R80 Valve Body we are specifically addressing this circuit from 6 PSI to a whopping 20 PSI. This is a 250% improvement from the factory calibration, resulting in reduced frictional heat generated. This reduction in heat helps lessen pre-mature failure that can become increasingly evident in high horsepower applications.\u003c\/p\u003e\n\u003cp\u003eAnother modification to our SunCoast Pro Loc 10R80 Valve Body involves the regulator valve (latch valve) circuit. This oil circuit is responsible for fully engaging the clutches, allowing for full clutch line pressure. In factory form, the regulator valve we are specifically targeting is responsible for A, B, C, and F clutch packs. Of course, our primary clutch pack concern is the 'F\" clutch, which tends to be the first and most prominent clutch pack failure with the 10R80 in higher horsepower or more demanding environments.\u003c\/p\u003e\n\u003cp\u003eIn a factory 10R80 valve body calibration, the regulator valve (latch valve) becomes fully engaged, allowing full fluid flow for engagement at 120 psi. When this occurs, the oncoming clutch pack has maximal clamping force. When the clamping force is engaged to max capacity, we ascertain the greatest static and dynamic holding capacity. In stock form or even mildly modified vehicles, this is perfectly suitable; however, when we expose the vehicle to a more demanding environment this can be a weak link.\u003c\/p\u003e\n\u003cp\u003eWith our SunCoast 10R80 Valve Body we are decreasing the required pressure to fully engage the regulator to only 80psi. This is a 33% decrease in pressure needed to maximally engage the clutch regulator valve (latch valve) resulting in a quicker shift apply when engaging clutches A, B, C and F. This quicker engagement not only shortens shift times, but it also decreases the heat resonating in the clutch pack, preventing premature degradation and extending clutch life. To improve this shift calibration even more SunCoast is evacuating non-critical oil to increase apply rate.\u003c\/p\u003e\n\u003cp\u003eThe factory overall line pressure is modified on this new SunCoast pump\/valve body combo.

However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R80 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford took the engineering lead on the design. The mission was to create a 10-speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R80 transmission was advanced enough to handle the power of the Ford Mustang GT 5.0 and Ford F150 Raptor, while improving the efficiency of the Ford Expedition and Lincoln Navigator.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R80 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off the line. Even though this Ford 10-speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R80 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003cbr\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003cbr\u003eReverse – 4.87\u003c\/p\u003e\n\u003cp\u003eAs shown above, this transmission offers a beautiful shift recovery in every gear, which lends itself to the perfect unit for narrow power bands. This allows the use of much larger camshafts in a naturally aspirated application. If you are looking into going to a forced induction setup, this shift recovery allows for larger turbo and AR housing for max performance.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNewly Designed Thermal Flow Control Filter\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis 10R80 transmission has a newly designed filter that has two types of media, fine and coarse (medium). The course medium is common in most filters (orange filter paper), and the fine medium filtration (White paper) is the newer material. There is a thermal plate inside the filter that separates the coarse and fine media. When the oil is colder (higher viscosity) at startup, the fluid will flow through both the fine and coarse filter media.\u003c\/p\u003e\n\u003cp\u003eAs the fluid heats up (less viscosity), the thermal plate will bend and restrict the coarse media section, directing most of the fluid through the fine media and, therefore, catching more of the finer debris once the fluid is heated giving it a far superior filtration system.\u003c\/p\u003e\n\u003cp\u003eThis new SunCoast 10R80 rebuild kit comes with a new factory filter to ensure zero flow issues.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe Clutches \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eRaybestos Powertrain GPZ friction plates greatly increase transmission performance and durability.

Since its debut in 2018, Suncoast has been actively involved in the research and development of this new platform. With our active partnership with Raybestos Powertrain, we can now deliver you the very best product to date with the 10R80 platform.

Where the problem lies is in its own clutch responsibilities when engaged in 6th gear as the oncoming clutch. With this responsibility in higher horsepower or more demanding driving situations, it becomes very obvious uptown teardown this clutch has seen its share of abuse.\u003c\/p\u003e\n\u003cp\u003eSuncoast provides GPZ friction material, providing higher friction coefficients, increasing torque capacity well beyond the factory limits. This, along with our higher apply pressure with our high-volume 10R80 transmission pump, creates the perfect environment for more reliable shifts. The new Suncoast 10R80 transmission clutch module requires absolutely no machining or modifications to your current unit...we supply everything needed.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eThe \"E\" Clutch\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eIf the 10R80 transmission had evil twin redheaded stepchildren, the \"E\" clutch would definitely be one of them. This other proverbial thorn in your side would be the \"F\" clutch.\u003c\/p\u003e\n\u003cp\u003eThis clutch, the \"E\" clutch in a 10R80 transmission, is engaged in 1,3,5,6,7,8, and 9th. The real issue becomes apparent pretty quickly. This clutch is cycled on 3 times and off 2 times by the time you are in 5th gear. The clutch is on in 1st then cycled off in 2nd, cycled back on in 3rd, then back off in 4th...only to be cycled back on in 5th gear. In higher-horsepower or higher-demand towing and hauling situations, this constant cycling on and off can lead to premature failure. \u003c\/p\u003e\n\u003cp\u003eSuncoast has addressed this issue with the 10R80 transmission by improving the clutch friction properties with the New Raybestos GPZ material and increasing clutch capacity by a whopping 20%. This takes the clutch stack-up from a factory 5-clutch stack-up to a 6-clutch stack-up. We are simultaneously addressing the heat issue with both improved friction coefficient as well as increasing surface area. This Suncoast 10R80 transmission \"E\" high capacity comes completely assembled and stacked up with a new (not used) OE machined drum, piston, and backing plate.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eThe \"F\" Clutch\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThis clutch is also prone to premature wear as we have seen with other Lepelletier Ravigneaux Gear sets...oncoming clutches in higher gears seem to take the brunt of the beating. With the new 10R80 transmission, the \"F\" clutch is no exception.\u003c\/p\u003e\n\u003cp\u003eThe \"F\" clutch is engaged in R,4,5,6,7,8 and 9th. The quickest path to early or premature degradation of this clutch pack is wide-open throttle or heavy-load-indexed 3rd to 4th shifts. This is especially prominent in applications where torque management has been deleted.\u003c\/p\u003e\n\u003cp\u003eSuncoast has corrected this issue by adding 25% more capacity to this clutch pack by taking it from 4 clutches to 5 in this particular clutch pack.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eThe Pro Loc Valve Body and Pump\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eWith the SunCoast 10R80 Pro Loc valve body, we are addressing several key issues we have seen regarding the 10R80 transmissions. This is not an approach that is simply bumping in more line pressure in hopes of ascertaining more clamping force; it’s a multi-faceted approach addressing several key issues when exposing these units to more demanding driving environments. These range from heavy towing and hauling to street racing and drag racing. \u003c\/p\u003e\n\u003cp\u003eThe factory 10R80 transmission lock-up circuit is an impressive one, in that it can make converter lockup seem somewhat uneventful. The refinement in its engagement is definitely next-level to what we have seen in the past. As nice as this feels in reference to the NVH (Noise Vibration Harshness), when we start introducing situations where the load demands are testing the limits or outside what the vehicle was initially designed for, it can become a huge problem. \u003c\/p\u003e\n\u003cp\u003eIn our SunCoast 10R80 Pro Loc Valve Body, we are specifically looking to decrease the time from initial lock-up apply to zero turbine slip. In doing this, we are changing the lockup circuit by replacing the torque converter clutch (TCC) valve in order to increase lockup holding apply fluid pressure. The lockup oil transition time is also improved by modifying critical oiling circuits for the fluid to reach the TCC clutch, resulting in quicker apply time, and therefore, reducing TCC clutch degradation. By reducing degradation per apply cycle, we are allowing for improved reliability and performance.\u003c\/p\u003e\n\u003cp\u003e(\u003cstrong\u003e\u003cem\u003eNOTE:\u003c\/em\u003e\u003c\/strong\u003e For maximum results in power levels exceeding 800HP, it is highly recommended that the TCC apply offset be changed in the factory file calibration)\u003c\/p\u003e\n\u003cp\u003eThe next facet we address is the lube circuit. The lube circuit on the 10R80 transmission is responsible for supplying oil to the planets, clutches, bushings, etc. From the factory, the lube circuit oil is dispersed throughout the transmission as low as 6 PSI. Under normal load demands, this is perfectly acceptable. In more stressful and demanding situations, an increase in lubrication to clutches, steels, and planets is ideal for removing heat and dealing with the increased demands. \u003c\/p\u003e\n\u003cp\u003eIn our 10R80 Valve Body we are specifically addressing this circuit from 6 PSI to a whopping 20 PSI. This is a 250% improvement from the factory calibration, resulting in reduced frictional heat generated. This reduction in heat helps lessen premature failure that can become increasingly evident in high-horsepower applications.\u003c\/p\u003e\n\u003cp\u003eAnother modification to our SunCoast Pro Loc 10R80 Valve Body involves the regulator valve (latch valve) circuit. This oil circuit is responsible for fully engaging the clutches, allowing for full clutch line pressure. In factory form, the regulator valve we are specifically targeting is responsible for A, B, C, and F clutch packs. Of course, our primary clutch pack concern is the 'F\" clutch, which tends to be the first and most prominent clutch pack failure with the 10R80 in higher horsepower or more demanding environments.\u003c\/p\u003e\n\u003cp\u003eIn a factory 10R80 valve body calibration, the regulator valve (latch valve) becomes fully engaged, allowing full fluid flow for engagement at 120 psi. When this occurs, the oncoming clutch pack has maximal clamping force. When the clamping force is engaged to max capacity, we ascertain the greatest static and dynamic holding capacity. In stock form or even mildly modified vehicles, this is perfectly suitable; however, when we expose the vehicle to a more demanding environment this can be a weak link.\u003c\/p\u003e\n\u003cp\u003eWith our SunCoast 10R80 Valve Body, we are decreasing the required pressure to fully engage the regulator to only 80psi. This is a 33% decrease in pressure needed to maximally engage the clutch regulator valve (latch valve) resulting in a quicker shift apply when engaging clutches A, B, C and F. This quicker engagement not only shortens shift times, but it also decreases the heat resonating in the clutch pack, preventing premature degradation and extending clutch life. To improve this shift calibration even more, SunCoast is evacuating non-critical oil to increase apply rate.\u003c\/p\u003e\n\u003cp\u003eThe factory overall line pressure is modified on this new SunCoast pump\/valve body combo. SunCoast is increasing overall main line pressure as much as 60psi. This additional line pressure not only increases the maximal clamping force of the individual clutch packs but also increases overall pump volume production. To reduce the potential for runaway pressure and the over-compression of clutch fibers, the SunCoast 10R80 Valve Body has a built-in bypass, dumping excessive pressure above 420psi.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIncreased Line Pressure, as much as 60psi\u003c\/li\u003e\n\u003cli\u003eIncreased clamping force on all clutch packs\u003c\/li\u003e\n\u003cli\u003e250% Increase in Cooler Charge Pressure\u003c\/li\u003e\n\u003cli\u003eIncreased Lock-up Apply Pressure\u003c\/li\u003e\n\u003cli\u003e33% Decrease in Maximal Pressure Actuation of Clutch Packs\u003c\/li\u003e\n\u003cli\u003eShortened Shift Times\u003c\/li\u003e\n\u003cli\u003eImproved Clutch Wear \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eThe Flex Plate\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe new 10-speed platform that resides in the Coyote-powered vehicles is nothing short of spectacular.

Stock clutch capacity.","description":"\u003cp\u003eCar makers don’t often collaborate on projects, especially when they’re direct competitors. However, looming government fuel economy and emissions mandates can make strange bedfellows. And so, the Ford 10R60 10-speed automatic transmission was born. It was co-developed with General Motors, although Ford apparently took the engineering lead on the design. The mission was to create a 10 speed transmission that could improve both the fuel efficiency and performance of high-horsepower engines. The resulting Ford 10R60 transmission was advanced enough to handle the power of the Ford Explorer and Ford Bronco.\u003c\/p\u003e\n\u003cp\u003eLike it or not, a CVT transmission is one of the most efficient gearboxes ever invented. Because there are no actual gears, optimal engine speed can be continuously maintained depending on the load. This allows for seamless acceleration under hard throttle, and lower fuel consumption when you’re just cruising. On a traditional geared transmission, a certain amount of energy gets lost every time a gear ratio is changed. This penalizes both fuel economy and performance, because the engine has to climb back to the RPMs it was just at. The Ford 10R80 10-speed transmission is designed to combine the efficiency benefits of a CVT, with the stepped feel of a traditional automatic transmission.\u003c\/p\u003e\n\u003cp\u003eTo create this optimal blend of performance and efficiency, the 10R60 transmission has a wide 7.39 gear ratio spread and a low 4.70 first gear for maximum performance off-the-line. Even though this Ford 10 speed automatic transmission has such a wide gear ratio, it has extremely small steps between the gears. This means the engine RPM only drops (approximately) 20% with each shift, which keeps the engine in the ideal RPM range to achieve either peak performance or efficiency (much like a CVT transmission). The Ford 10R80 also has three overdrive gears, which it can downshift from very quickly.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e10R60 Transmission Gear Ratios\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFirst – 4.70\u003cbr\u003eSecond – 2.99\u003cbr\u003eThird – 2.15\u003cbr\u003eFourth – 1.80\u003cbr\u003eFifth – 1.52\u003cbr\u003eSixth – 1.28\u003cbr\u003eSeventh – 1.00\u003cbr\u003eEighth – 0.85\u003cbr\u003eNinth – 0.69\u003cbr\u003eTenth – 0.64\u003cbr\u003eReverse – 4.87\u003c\/p\u003e\n\u003cp\u003eAs shown above this transmission offers a beautiful shift recovery in every gear which lends itself the perfect unit for narrow power bands.
