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transmission features \u003cstrong\u003eclutch-to-clutch shifting\u003c\/strong\u003e, eliminating the outdated bands used in earlier designs.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. This capability greatly improves fuel efficiency, closing the gap between automatic and manual transmissions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe SunCoast Mission: Redefining the 6L80E\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e At SunCoast Performance, we recognized the common problems associated with the 6L80E and made it our mission to \u003cstrong\u003ecorrect and alleviate these issues\u003c\/strong\u003e with a completely redesigned and remanufactured valve body. From the very beginning, we set out to engineer a solution that not only resolves these flaws but also elevates the overall performance of the transmission.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSunCoast Remanufactured 6L80E Valve Body: Built for Reliability\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDrive.

The eight solenoids are connected to the TCM via a lead frame, all of which are over-molded in the plastic housing and not accessible or serviceable separately. Component fails and circuit faults in the TEHCM are common, and result in drivability complaints and trouble codes which can only be remedied with a replacement unit.\u003c\/p\u003e\n\u003cp\u003eA Sonnax TEHCM delivers durable, reliable OE performance. Each unit goes through a rigorous cleaning and inspection process where all failed components are replaced. Electro-hydraulic testing in a simulated drive test ensures full functional performance consistent with a new OE TEHCM. A vehicle VIN remains on the Sonnax remanufactured TEHCM, and will be overwritten by the transmission shop technician with the new vehicle VIN during the reprogramming process. After installation, this remanufactured TEHCM must be reprogrammed on the vehicle using a J2534 device in order to function correctly.\u003c\/p\u003e\n\u003cp\u003eThe fully tested TEHCM is serialized, and the test data stored and packaged in mylar bag with a protective connector cover to prevent inadvertent static discharge issues during the shipping, handling and receiving processes.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eUltrasonically cleaned and thorough flushing of solenoids to remove all dirt and debris — no matter how hidden\u003c\/li\u003e\n\u003cli\u003eNew pressure switches installed\u003c\/li\u003e\n\u003cli\u003eNew filter plate\/screen included\u003c\/li\u003e\n\u003cli\u003eFully electro-hydraulically tested to comply with OE performance\u003c\/li\u003e\n\u003cli\u003eMust be reprogrammed after installation using a J2534 device for proper function\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe SunCoast Standard\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSince 1989, SunCoast Performance has led the way in transmission innovation and engineering.
