Does District of Columbia vehicle inspection or emissions testing affect this service?
The District of Columbia requires a biennial safety and emissions inspection for registered vehicles through the DMV. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all District of Columbia and federal requirements.
What is a TEHCM and why does replacing the solenoid pack need programming?
The TEHCM (Transmission Electro-Hydraulic Control Module) is GM's transmission control module — and on the 6L and 6T six-speeds it is integrated into the valve body / solenoid pack rather than being a separate box. So when a mode-switch or solenoid fault forces you to replace the pack, you replace the module too. The new pack carries no VIN, no calibration, and none of your transmission's learned adaptation, so it has to be programmed to your car before it will shift correctly. Cloning your original's data onto the donor is how we do that on the bench.
Which GM transmissions does this cover?
The RWD 6-speeds and the FWD / AWD 6-speeds. On the RWD side: 6L45 (Cadillac CTS 3.6 RWD, ATS 2.0T / 2.5) and 6L50 (Camaro V6, CTS / CTS Coupe, SRX, STS, and 2012-2016 Colorado / Canyon), plus 6L80 (Silverado / Sierra 1500, Tahoe, Suburban, Yukon, Avalanche, Camaro SS, Pontiac G8, Chevrolet SS, CTS-V) and 6L90 (Silverado / Sierra 2500HD and 3500HD, Suburban 2500, Yukon XL 2500, Escalade, Express / Savana). On the FWD / AWD side: 6T70 (Malibu, Equinox, Terrain, Impala, LaCrosse, Regal, Captiva Sport), 6T75 (Traverse, Acadia, Enclave, Impala 3.6, LaCrosse 3.6) and 6T80 (heavier FWD / AWD crossovers). Roughly 2006-2020 depending on platform. Send your VIN and a photo of the module / solenoid-pack part-number label and we confirm your exact application before you ship.
