• 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.
• Our upgrade-only option will upgrade your TCM to enable tuning. Send us your TCM and we'll send it back to you fully upgraded for tuning. Please include VIN. This service takes 1-3 business days to complete (not including shipping times).
