TCM Unlock Only Service
HP Tuners now offers tuning support for the T87A equipped 2017+ GM 10-Speed and 8-Speed transmissions in the latest version of VCM Suite. Simply send us your T87A TCM, include your VIN above and we will send it back unlocked.
Due to the added complexity of these transmission control modules, the T87A for the GM 10-speed and 8-Speed requires individual licensing of 4 GM Credits (MPVI) or (4) Universal Credits (MPVI2, MPVI2+, MPVI3) for tuning.
TCM Unlock & Program Service
You can now send us your T87A TCM (new or old) and we will pre-program it for your specific VIN so it’s ready to plug in and you can start tuning immediately—no need for the GM factory tool. Simply select “Unlock & Program” from the dropdown box above and ensure you include your VIN.
Note: If you are removing the T87A TCM from your vehicle and plan to reinstall it in the same vehicle, you do not require this service.
Note: T87A TCM Services support a variety of 10LXXE equipped vehicles. Our latest support covers the majority of 2017-2018 vehicles with the following exceptions/additional applications:
- 2017-2020 Camaro ZL1
- 2018 – Escalade, Suburban, Tahoe, Yukon
- 2019 – Camaro SS (excluding partial year switch to T93 TCMs)
- The TCM you send in should already be programmed prior to the unlock service. If you choose to send in a spare TCM, you are responsible for providing us accurate vehicle information at the time you place your order and for later having the TCM programmed via a J2534 tool or OEM Dealer Diagnostic tool to your vehicle.
- After the TCM arrives at HP Tuners, an HP Tuners engineer will unlock the TCM and enable your HP Tuners software so that the TCM can then be licensed, edited, and flashed with HP Tuners software! This is a one-time unlock that will not affect other operations of the TCM. The factory tools will still work for service and HP Tuners will then work for tuning!
- Once you receive the TCM back from unlock, re-install the TCM back into the vehicle, and then you may tune the TCM with HP Tuners by licensing the TCM for (4) credits.
