Let Tick arrange the un-locking service of your GM T87A transmission control module. Include your VIN in the order notes, then wait for further instruction via email before shipping your tcm to HP!! You may also choose to purchase individual credits for your device at the same time, or order a new MPVI2 with sufficient credits as tuning these transmissions will require 4 credits in addition to the credits required to tune the ecm.
HP Tuners is proud to release limited tuning support for the T87A equipped 2017 GM 10-Speed and 8-Speed transmissions in the latest version of VCM Suite Beta. This release provides the first and only 10-Speed and 8-Speed transmission tuning solution for 2017 GM Vehicles. Due to added complexity, the T87A TCM for the GM 10-speed and 8-Speed requires individual licensing of 4 GM Credits (MPVI) or 4 Universal Credits (MPVI2) for tuning.
Please note, due to increased security, ALL T87A TCMs need to be unlocked via the GM Unlock service before they can be tuned. More information on this new process can be found below:
HP Tuners is proud to release a TCM Unlock service that enables tuning on 2017 T87A TCMs. The cost for the service is $200 and can be purchased through the Order Page near the bottom of the page.
Once ordered, please ship your TCM to the following address for unlock:
HP Tuners, LLC 701 Dartmouth Ln Buffalo Grove, IL 60089
If the information above is not provided with the TCM, it may delay the TCM Unlock process while the missing information is acquired.
NOTE: 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, a 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!
We will unlock TCMs as fast as we can, but please allow 1 – 2 business days (plus the time to ship the TCM) per TCM that you send in for the unlock process to finish. (i.e. 2 PCMs = 2-6 business days.)
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.
