T93 TCM Unlock Service

2019+ GM Vehicles Equipped with the T93 Transmission Control Module 8 Speed / 10 Speed Equipped (NON-GLOBAL B)

Five Bar Motorsports offers a T93 Transmission Control Module (TCM) unlock service for late model GM vehicles equipped with the factory locked T93 transmission controller. From the factory, these modules are encrypted and cannot be accessed by standard tuning software. Our unlock service allows the TCM to be fully accessible so proper transmission tuning and calibration adjustments can be performed.

Unlocking the T93 TCM is required for vehicles receiving performance upgrades or for those looking to improve shift quality, shift speed, torque management, and overall transmission performance.
