Absolutely not. We handle all the programming before the module ships. Simply provide your 17-digit VIN during the checkout process, and the part will arrive ready for installation and operation.
Is this compatible with my GMC Sierra 2500?

Where is this module located on the truck?
The TCM is typically located on the driver’s side of the engine bay, mounted to the fan shroud for cooling. It’s a relatively accessible component for replacement.
