Simply install the part, disconnect the battery for 15 minutes to clear adaptive memory, and you’re ready to go.
Where is the TCM located on my 2007-2008 Avalanche?
On the 2007-2008 Chevrolet Avalanche 1500, the T42 Transmission Control Module is typically located in the engine compartment, next to the battery. Always confirm the location before beginning work.
How do I provide my VIN for programming?
You can enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy, as this is crucial for correct programming.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a failing TCM is a very common cause, this code can also be triggered by other transmission issues. Replacing a known faulty TCM is often the correct fix. We recommend having the vehicle scanned for all specific transmission codes (e.g., P0751, P0756) to confirm the diagnosis.

Does this part fit other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 GM trucks, vans, and SUVs that use the 4L60E, 4L65E, or 4L70E automatic transmissions. The key is our VIN-specific programming, which makes this 2007-2008 Avalanche 1500 programmed TCM a perfect fit for your specific application.
