Our GM T93 Global B TCM Service has been expanded to include every variation of T93 unit used across GM’s latest Global B platforms—including the 2024–2026 Silverado and Sierra HD 6.6L L5P Duramax.
Please note: This is an unlock service only; tuning is available as an additional service.
I acknowledge I am sending in the ORIGINAL ECM/PCM from my GM Global B vehicle, NOT a spare ECM
Benefits of tuning the TCM include:
- Increased line pressure
- Modified torque management
- Adjusted lock-up schedule
- Customized shift points
- Enhanced overall driveability
This service is especially beneficial for heavy towing, hard driving conditions, high horsepower applications, and can help prolong the life of your transmission.
