Important Note
This TCM is fully programmed and updated and does not require additional programming after installation.
Simply install the unit and the vehicle will recognize it automatically.
If your original TCM has unique calibration or custom parameters, we also offer a TCM Cloning Service, which transfers all data-including VIN, shift adaptations, and configuration settings-into the replacement unit.
