Our VIN-specific programming loads the latest GM software and calibrates the unit specifically for your vehicle’s factory setupโincluding its engine, axle ratio, and tire size. This is why our modules work perfectly right out of the box, preventing the performance issues and communication errors common with un-programmed parts.

Frequently Asked Questions
Do I need to program this module after I receive it?
No. This is the primary benefit of our service. The module arrives pre-programmed to the specific VIN you provide during checkout. It is ready for a plug-and-play installation with no further flashing or dealership visits required.
Where is the TCM located on my 2007-2009 GMC Yukon?
On most 2007-2009 GMC Yukon, Tahoe, and similar GM trucks/SUVs, the T42 TCM is conveniently located in the engine compartment, typically mounted next to the battery. Always disconnect the battery before beginning the replacement process.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the ECM to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, it’s important to have the vehicle scanned for more specific codes (like P0750, P0751, etc.) to confirm the TCM is the root cause. This part is designed to fix those specific internal TCM and solenoid circuit faults.
What tools are needed for installation?
Installation is typically very straightforward. You will generally only need basic hand tools, such as a socket set (commonly 10mm) to remove the mounting bolts and a flathead screwdriver to help release the wiring harness clips. The entire process often takes less than 30 minutes.
Is there a core charge for my old part?
No, there is no core charge associated with this 2007-2009 GMC Yukon Transmission Control Module. You can keep your old part, which simplifies the process and saves you the time and expense of return shipping.
