GM T87A TCM Services

HP Tuners is pleased to offer brand-new GM T87A TCMs for purchase. This TCM is found in various 2017+ GM vehicles with 10-speed and 8-speed transmissions and 2015-2019 GM vehicles with the 6-speed transmission.

Good news—The GM T87A TCM no longer requires an upgrade! Users can now simply license and tune their T87A TCM without any upgrade. Normal vehicle licensing still required. Please only purchase this if you specifically need a brand-new GM T87A TCM for your vehicle.
