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.
