2017+ GM 10-Speed Now Supported!

Vector Motorsports is proud to announce tuning support for the T87A equipped 2017+ GM 10-Speed transmissions!

Due to the complexity of this transmission and requirements, the T87A TCM for the GM 10-speed needs to be individually licensed for additional GM credits for tuning and therefore some increased costs.

Please also note, that due to increased security setups, ALL T87A TCMs need to be unlocked via the TCM Unlock Service before they can be tuned. That means that we have to send out your TCM to our GM tuning software provider (HP Tuners) to be unlocked. This unlocking service will require additional fees as well as shipping costs.

A spare TCM can be purchased, unlocked, and used in place of the stock one, but please contact us first regarding these TCMs and your vehicles special requirements. This is a one-time unlock that will not affect other operations of the TCM. The factory tools will still work for service and our tuning software will then work for tuning!

Estimated Unlocking/Programming for TCM Software (not including actual tuning time) will range from 1 – 3 business days (plus the time to ship the TCM) per TCM.

Please contact our shop for more information, as well as scheduling your custom tuning needs!
