Sonnax remanufactured valve body GM6L80E has been designed to address common issues, such as: burnt clutches; codes P0751, P0741, P0742; harsh TCC apply; bump, harsh or flare shifts; bind-ups; solenoid performance codes; and wrong gear starts. To guarantee the highest level of operational performance, this remanufactured valve body is tested on state-of-the art equipment to verify that actuator feed limit pressure, clutch pressures, torque converter pressures and compensator feed pressures match OE specification. A TEHCM is not included with the valve body, but is available from OE and various aftermarket sources if required. A common fault with the TEHCM is failed pressure switches, which can be easily checked and repaired using Sonnax kits [124740-28K] or [124740-30K], if required. Bores, plates, checkballs, seals, casting…every critical area is reviewed, refreshed and repaired Top-quality Sonnax components optimize valve body function and prevent future wear State-of-the-art testing verifies AFL, clutch, TC and compensator feed pressures match new OE specs
