Is Your Yukon’s Transmission Acting Unpredictable?
There’s nothing more frustrating than a vehicle you can’t rely on. If your GMC Yukon is suffering from harsh shifting, getting stuck in gear, or throwing transmission-related check engine lights, you’ve lost the confidence you need in your family’s primary vehicle. A faulty Transmission Control Module (TCM) is often the culprit, disrupting communication and causing erratic behavior. This VIN-programmed T42 TCM is the definitive, hassle-free solution to restore your truck’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing TCM can manifest in several ways, turning your dependable SUV into a source of stress. If you’re experiencing any of the following, it’s a clear sign you need a replacement:
- Abrupt, harsh, or delayed gear shifts
- The vehicle enters “limp mode,” often stuck in 2nd or 3rd gear
- Check Engine Light is on with diagnostic trouble codes (DTCs) like P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift properly, leading to poor acceleration and fuel economy
- Complete loss of communication with the transmission
This module is the direct solution to these problems. As a critical component, a new, properly programmed 2007-2009 GMC Yukon transmission control module doesn’t just fix the symptoms—it restores the core logic that makes your transmission operate smoothly and efficiently.

Expert Insight: Why VIN Programming is Non-Negotiable
On modern GM vehicles like your Yukon, the TCM is part of a complex network of computers that constantly communicate. VIN programming isn’t just a convenience; it’s essential. It loads your vehicle’s exact software, including any factory updates, and calibrates the module for your specific transmission and engine combination. Installing a non-programmed or incorrectly programmed module can lead to persistent shifting problems or even damage to your transmission. Our process ensures this 2007-2009 GMC Yukon transmission control module integrates perfectly from the moment you plug it in.
Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we use your vehicle’s unique 17-digit VIN to load the latest GM-certified software directly onto the module before we ship it. This ensures it works perfectly with your Yukon’s specific systems right out of the box, with no additional programming required.
Is this a difficult part to install myself?
For most DIYers, this is a straightforward job. The TCM on a 2007-2009 Yukon is typically located in the engine bay, next to the battery. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, swapping it with the new one, and reconnecting everything. The entire process usually takes less than 30 minutes.
Will this fix my P0700 check engine light code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s important to have the specific transmission codes (e.g., P0751, P0756) read to confirm the diagnosis. In a vast majority of cases where the TCM is faulty, this part is the correct fix.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module without the hassle of returning it, making the repair process simpler and faster.
