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 business day to complete (not including shipping times).

Contact us if you want different VIN on your TCM

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

Upgrade 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.

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