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 and Pump Combo 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 Valve Body and Pump combo. SunCoast is increasing overall main line pressure as much as 60psi. This additional line pressure not only increases maximal clamping force of the individual clutch packs but increases overall pump volume production. To reduce the potential for runaway pressure and the over-compression of clutch fibers, the SunCoast 10R80 Valve Body does have 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\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/U1KKt9RSsPk\" frame allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ciframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/pKBXMSpQnrw\" frame allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e","brand":"SunCoast Performance","offers":[{"title":"Default Title","offer_id":49129470525659,"sku":"SC-10R80-PVB","price":2195.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198648863.jpg?v=1786544528"},{"product_id":"10l1000-10l80-10l90-10r140-10r80-solenoid-stabilization-clip-insert","title":"10L1000, 10L80, 10L90, 10R140, 10R80 Solenoid Stabilization Clip Insert","description":"\u003ch2\u003e10L80, 10L90, 10R140, 10R80\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eSolenoid Stabilization Clip Insert\u003c\/strong\u003e\u003cbr\u003e Part No. 105740-01K\u003c\/p\u003e\n\u003cp class=\"sans\"\u003ePackage Quantity: \u003cstrong\u003e6\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIn GM 10L80\/90 and Ford 10R80\/140 10-speed transmissions, heavy linear force solenoids (LFS) are held in place by small spring retainers.

When the spring retainer collapses and allows the LFS to be off-center, the pintle cannot stroke the clutch control valve appropriately, compromising the component apply timing and pressure, resulting in shift complaints and converter issues.

Sharing its design roots with the smaller 6L45 and 6L50, built in GM Powertrain’s Strasbourg, France facility, the 6L80E is known for its advanced engineering and reliability.\u003c\/p\u003e\n\u003cp\u003eThis transmission features \u003cstrong\u003eclutch-to-clutch shifting\u003c\/strong\u003e, eliminating the outdated bands used in earlier designs. Its \u003cstrong\u003eLepelletier gear mechanism\u003c\/strong\u003e, which combines a conventional planetary gearset with a compound Ravigneaux gearset, reduces size and weight while enhancing efficiency. Unlike traditional automatic transmissions, the 6L80E does not utilize a direct gear ratio, making it one of the few transmissions with this innovative design.\u003c\/p\u003e\n\u003cp\u003eFurther setting it apart, the 6L80E can achieve \u003cstrong\u003etorque converter lock-up on all six forward gears\u003c\/strong\u003e while completely disengaging at a standstill.
