Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. This is the key benefit of our service. We pre-program the module to your vehicle’s exact VIN before shipping it. This makes the installation plug-and-play, saving you time and money.
Where is the TCM located on my 2007-2008 Yukon XL 1500?
On this specific model, the Transmission Control Module is typically located in the engine compartment, right next to the battery. Always disconnect the battery’s negative terminal before beginning the replacement.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause (like a failed internal driver), you should always have the specific transmission codes read to confirm the diagnosis. This part is designed to fix internal TCM failures that trigger such codes.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is very straightforward and typically takes less than 30 minutes. It involves disconnecting the battery, unplugging a few electrical connectors, and removing a few bolts. No special tools are required.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe and costly problems. Continued harsh shifting can cause premature wear on internal transmission components like clutches and bands, potentially leading to a complete transmission failure requiring a full rebuild or replacement.
