The GM Gen. 2 6T70/75/80 TEHCM houses the transmission control module (TCM) and solenoids. Component failures and circuit faults in the TEHCM are common, and results in drivability complaints and trouble codes which can only be remedied with a replacement unit.
Sonnax remanufactured TEHCM GM6T70-G2-TEHCM delivers durable, reliable OE performance at a significant savings over an OE replacement. 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.
The 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.
- Ultrasonically cleaned and thorough flushing of solenoids to remove all dirt and debris — no matter how hidden
- New filter plate/screen included
- Fully electro-hydraulically tested to comply with OE performance
- Must be reprogrammed after installation using a J2534 device for proper function
Sonnax TEHCMs have "Sonnax" lasered on them for quality assurance purposes. Sonnax TEHCMs are serialized with a unique number, and the data from each TEHCM during its final testing is stored for future review. Please log your serial numbers as this will help with any diagnostic questions you may have. See web image for reference.
Symptoms
- Solenoid electrical circuit faults
- Solenoid performance codes
- Gear ratio codes
- Poor shift quality
- TCC codes
- Internal memory codes
- Temperature sensor codes
Cause
Internal component failure or circuit faults within the TEHCM creates no or poor communication with the onboard TCM, resulting in poor shift quality and numerous diagnostic trouble codes.
Correction
Install a remanufactured Sonnax TEHCM that has been thoroughly cleaned and updated with new components where necessary and electro-hydraulically tested for OE performance in a simulated drive test.
