That’s correct. We handle all the programming before the part is shipped to you. Once you provide your vehicle’s VIN during checkout, we flash the module with the latest GM software for your specific vehicle. This makes the installation plug-and-play.
Where is the TCM located on my Tahoe?
On the 2007-2009 GMT900 platform trucks and SUVs like the Tahoe, the Transmission Control Module is typically located in the engine bay, next to the battery.
What tools are required for installation?
Installation is straightforward and typically requires only basic hand tools, such as a socket set to disconnect the battery and remove the module’s mounting bolts. The entire process usually takes less than 30 minutes.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe and costly transmission damage. Continued harsh shifting can cause excessive wear on internal components like clutches and bands, potentially leading to a complete transmission failure that requires a full rebuild or replacement.
