An Expert’s Note on VIN Programming
Why is VIN programming so important? Your Yukon isn’t just a generic SUV; it has specific options, gear ratios, and tire sizes that the TCM must know about. A generic, non-programmed module from a salvage yard or a big-box store can’t account for these variables, often leading to continued poor performance or even new error codes. Our process ensures the module is a perfect electronic match for your vehicle right out of the box, just as the factory intended.
Frequently Asked Questions
Do I need to take my Yukon to the dealer after installation?
No. Because this 2007-2009 Yukon transmission control module is pre-programmed to your specific VIN, no further dealership flashing or programming is required. It is designed for a direct, plug-and-play installation.
Where is the TCM located on my 2007-2009 Yukon?
On most 2007-2009 GMC Yukon, Tahoe, and similar GM trucks/SUVs, the T42 TCM is located in the engine compartment, typically mounted next to the battery. Always disconnect the battery before beginning the replacement.
How do I provide my VIN for programming?
After you place your order, you will be prompted to provide your vehicle’s 17-digit Vehicle Identification Number (VIN). Our technicians use this to load the correct factory software onto your module before shipping.
Will this fix a P0700 trouble code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. While a faulty TCM is a very common cause, this code can also be triggered by other issues. However, if you’re experiencing the shifting symptoms listed above along with a P0700, replacing the TCM is the most likely solution.
Is there a core charge for my old part?
No, there is no core charge required for this module. You can keep your old part without the hassle of returning it.
