2017-2019 Duramax HP Tuners Modified T87A TCM (HP-L5P-T87A-TCM)
Ready to tune your GM vehicles’ transmission with HP Tuners? We are pleased to offer custom tuning support for the GM T87A TCM found in 2017+ GM vehicles with the 8-speed or 10-speed transmission as well as 2015-2019 GM vehicles with the 6-speed transmission.
Due to the complexity of this controller, all T87A TCMs must be upgraded via one of the upgrade options below to enable tuning in VCM Suite (BETA). Once upgraded, users can access important transmission parameters in our software within shift scheduling, shift pressures, shift timing, torque management, and more to improve drivability and power delivery. Plus, our solution provides this access directly via the OBDII port using an HP Tuners interface.
Gives you the ability to tune your 8-Speed or 10-Speed Transmission with an MPVI/MPVI2 and VCM Suite
