HP Tuners Releases Tuning Support for the T87A-Equipped 2017 GM 8-Speed and Allison A1000

Print

The 2017 GM full-sized trucks offer an 8-speed Allison transmission that have been found in earlier models, but are now equipped with updated software that makes tuning a challenge. Up until this point it was nearly impossible to do so, but luckily for those who own one of these vehicles, HP Tuners is quick to offer a solution!

Official Release:

HP Tuners is Proud to Release Limited Tuning Support for the T87A-Equipped 2017 GM 8-Speed and Allison A1000 in VCM Suite 3.5 Beta

This release provides the first and only 8-Speed/Allison transmission tuning solution for 2017 GM Vehicles. We’ve worked tirelessly to provide a solution for customers who have a critical need to tune these transmissions. Due to added complexity, the T87A TCM needs to be individually licensed for 4 GM credits for tuning.1

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

When you send in the TCM, you MUST include the following:

1. Customer Name
2. Customer Address
3. Customer Contact Information (E-mail/Phone)
4. TCM Unlock Service Order #
5. Vehicle Identification Number
6. Preferred shipping method2
PROCHARGER650X300

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 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!

We will unlock TCMs as fast as we can, but please allow 1 – 3 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. If need to purchase one of our tuning interfaces, the GM Pro VCM Suite is $649, it comes with the interface, VCM Suite, 8 GM Credits and can also be ordered here: Order Page

Please email Sales or Support if you have any further questions.

1(HP Tuners reserves the right to change this at any time.)

2Default shipping added with the unlock fee on our website is UPS ground.

Expedited shipping options include:

1. Including a prepaid return shipping label with TCM (This is the fastest way). (IMPORTANT: Shipping label must have a Tracking #. Prepaid packaging with postage stamps will not be accepted)
2. Paying for Overnight or 2nd day. Email Sales and Shipping with your address for a quote.
