Tune your 2017+ GM Transmission with HP Tuners

Ready to tune your GM vehicles’ transmission with HP Tuners? We are pleased to offer custom tuning support for the GM T87A TCM found in 2017+ GM vehicles with the 8-speed or 10-speed transmission as well as 2015-2019 GM vehicles with the 6-speed transmission.

Due to the complexity of this controller, all T87A TCMs must be upgraded via one of the upgrade options below to enable tuning in VCM Suite (BETA). Once upgraded, users can access important transmission parameters in our software within shift scheduling, shift pressures, shift timing, torque management, and more to improve drivability and power delivery. Plus, our solution provides this access directly via the OBDII port using an HP Tuners interface.

Upgrade Only Service

Our upgrade-only option will upgrade your T87A TCM to enable tuning. Simply send us your TCM and we’ll send it back to you fully upgraded for tuning. Make sure to include your VIN when checking out (always double-check your VIN for accuracy to avoid delays). This service takes 1-3 business days to complete (not including shipping times).

Note: Keep in mind that with this option, your TCM will be returned to you with the same programming. If you want the TCM to be pre-programmed to a different VIN, this is not the option for you. Please select “Upgrade & Program” instead.

Note: No need for an IMMO Relearn, Crank Relearn, or to perform the “Replace TCM” Function in VCM Scanner on the stock TCM.

Upgrade & Program Service

Our upgrade and program option allows you to send in your T87A TCM (new or spare) to be upgraded and pre-programmed for a specific VIN. Once upgraded and licensed, your TCM will be “plug and play” and can be tuned immediately—no need for the GM factory tool.

Simply select “Upgrade & Program” from the dropdown box above and ensure you include your VIN (please double-check your VIN for accuracy to avoid delays). This service takes 1-3 business days to complete (not including shipping times).

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. Please select the “Upgrade Only” option instead.

Note: No need for an IMMO Relearn, Crank Relearn, or to perform the “Replace TCM” Function in VCM Scanner on the stock TCM.

New Upgraded TCM Purchase

This option allows you to purchase a brand-new, already upgraded T87A TCM for your supported GM vehicle directly from HP Tuners. Your new TCM will already be upgraded for tuning and programmed to the VIN you add during checkout (please double-check your VIN for accuracy to avoid delays).

⚠️ Once you receive your new TCM, install it in your vehicle and follow the Replace T87A TCM Instructions. Then, license the controller and start tuning!

Everything you need to tune your T87A TCM vehicle with HP Tuners:

  1. Select one of the three options available above: Upgrade Only, Upgrade & Program, or New Upgraded TCM Purchase.
  2. Download the latest version of VCM Suite BETA for free here.
  3. Once upgraded, purchase (4) Universal Credits to license your T87A TCM/vehicle.
  4. Make sure you have an MPVI, MPVI2, MPVI2+, or MPVI3 interface.
    • Purchase a new MPVI3 here.
    • Upgrade your old device for MPVI3 here.

Note: Universal Credits for licensing are not included in the cost of any upgrade service or purchase. Credits must be purchased separately.

Note: We also support the T93 TCM found in 2020+ GM vehicles as well as some 2019+ GM vehicles (non-Global B) with the 8 and 10-speed transmissions. See our GM T93 TCM Services for more information.




  • The TCM you send in should already be programmed prior to the upgrade service. If you choose to send in a spare TCM, you are responsible for providing us with 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 upgrade 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 upgrade 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 upgrade, 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.

These steps only apply to the send-in upgrade services, NOT the new TCM purchase.

Step 1: Once you’ve confirmed your vehicle’s support, select the upgrade service that fits your needs best. If you select the Upgrade & Program option, please add your VIN to the box when adding to your cart.

  • If you’re new to HP Tuners, purchase a brand new MPVI3 here.
  • If you’re using an MPVI2+ or older generation interface, upgrade to the latest generation MPVI3 here.

Step 2: After placing your order with the necessary information, see the “Shipping” tab for a shipping form and address. Fill out and print this form to place in your shipping box. You will also receive an email immediately after placing your order with this shipping form and address.

Step 3: Remove the TCM from your vehicle and safely package it. Then, package your TCM safely with the shipping form.

Step 4: Write your order number on the outside of the shipping box.

Step 5: Ship your TCM to HP Tuners using any carrier you prefer. The shipping address can be found on this page and in the email discussed in Step 2. Shipping costs are the responsibility of the customer.

Step 6: HP Tuners will upgrade your TCM for tuning and diagnostics. Then, we’ll ship it back to you. The service takes 1-3 business days (not including shipping times).

Step 7: Once you receive your upgraded TCM, install it back into your vehicle. If you selected the “Upgrade & Program” option, please follow these instructions upon reinstallation. Then, license the upgraded T87A TCM by purchasing [4] Universal Credits (sold separately). Once licensed, start tuning with your MPVI3 interface and the latest version of VCM Suite BETA.

PRINT SHIPPING FORM

⚠️ NOTE: Any hardware ordered with this product will be shipped along with your upgraded ECM/PCM/TCM. To avoid any delays should you require other hardware soon, please order that hardware separately.

⚠️ NOTE: Customers are responsible for shipping costs when sending HP Tuners your ECM/PCM/TCM. The shipping charge at checkout only covers returning your control module after modification.

    • These ECM/PCM/TCM services are completed at the owner’s risk. HP Tuners will not be responsible for the vehicle, its powertrain, or electronics, nor how the control module is used, calibrated, and its functionality.
    • Due to the factory location of the TCM in the vehicle, all TCMs will exhibit signs of weathering and wear, which is completely normal.

Should you experience any issues with your TCM, please submit a ticket to our support team for assistance on how to proceed.
