The 6L80E transmission is widely used in such popular GM applications as the Silverado and Sierra trucks, Tahoe, Suburban, Denali, Hummer H2, Cadillac Escalade, STS and CTS, Camaro, and G8 .

The 6L80E transmission is prone to issues that include: 2-3 harsh or delayed shifts, harsh or delayed shifts from park or reverse, burnt 1-2-3-4, or 3-5 reverse clutch, check engine light (DTC P0751 Code), converter shudder due to flaking of the converter lining, shudder on low/reverse apply, TEHCM and/or CAN software malfunction.

JASPER remanufacturing advantages include:

• Early-style stator support shaft is modified for 100% installation of updated 1-2-3-4 and 3-5/reverse seal rings to prevent seal leakage, harsh/delayed shifts and burnt clutches.
• Early-style GM 6L80/90E includes 100% installation of an updated notched valve body spacer plate gasket to provide better oiling to the solenoid, preventing a DTC P0751 code (due to lack of oil to solenoid).
• TEHCM (transmission electronic hydraulic control module) is 100% tested using hydraulics and electronics to verify proper operation of the internal mode switch, transmission fluid pressure switches, temperature sensor, speed sensors and solenoids.
• 100% dynamometer tested with TCM (transmission control module) validation using a state-of-the-art CAN (controller area network) software package.
• JASPER offers their installers free rental of a J2534 pass-through device, with transmission purchase, to assist in the reprogramming of the TEHCM and ECM (engine control module) to ensure the latest OEM calibration is installed in the vehicle.
• J2534 reprogramming will require a subscription fee charged by General Motors.
