New GM Unlocked T87A TCMs
You can now purchase New GM T87A TCMs for your 2017+ GM vehicle equipped with the 10-Speed and 8-Speed transmissions directly from HP Tuners that are already unlocked and ready for tuning. Simply install your new HP Tuners TCM, and you are ready to tune with your MPVI / MPVI2 and VCM Suite.

Purchase & Installation Instructions
To purchase a new unlocked T87A TCM which is ready for tuning for your specific vehicle application, simply identify your Serv# which is located on the top of your T87A TCM, and finally provide your VIN.

Please note this page is NOT the TCM Unlock Service, you are purchasing a NEW GM T87A TCM which is already unlocked and pre-programmed for use in your vehicle.

Due to the added complexity, once unlocked the T87A TCM for the GM 10-Speed and 8-Speed needs to be individually licensed with 4 Credits allowing you to tune with your MPVI / MPVI2 and VCM Suite. Please note the MPVI3 and Credits are not included with this product and need to be purchased separately.
