GM T87A TCM Unlock Services

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.
