Is your 2007-2013 GMC Sierra 1500’s transmission letting you down? Unpredictable shifting, getting stuck in gear, or a persistent check engine light can sideline your truck and disrupt your day. This pre-programmed T42 Transmission Control Module (TCM) is the definitive, hassle-free solution to restore the crisp, reliable shifting and dependable performance you need. By programming this module to your vehicle’s specific VIN before it ships, we eliminate the need for an expensive trip to the dealership for programming. It arrives ready for a plug-and-play installation, getting you back on the road fast.
Common Symptoms & Your Solution
A failing TCM can cause a cascade of problems that are often misdiagnosed. If you’re experiencing any of the following, this module is your solution:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a noticeable delay when shifting.
- Stuck in “Limp Mode”: The vehicle refuses to shift past 2nd or 3rd gear as a protective measure.
- Warning Lights: A steady Check Engine Light or Transmission Warning Light on your dash.
- Diagnostic Trouble Codes (DTCs): Specifically codes like P0700, which indicates a general transmission fault, or various solenoid-related codes (e.g., P0750-P0758).
- Poor Performance: A sudden drop in fuel economy, failure to upshift or downshift, or a feeling of slipping out of gear.
Installing this expertly prepared 2007-2013 Sierra 1500 Transmission Control Module directly addresses the root cause of these electronic failures, restoring communication between your engine and transmission for flawless operation.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern GM vehicles, the TCM isn’t just a simple controller; it’s part of a complex network of modules that constantly communicate. Without precise VIN programming, a new TCM can’t properly ‘talk’ to the Engine Control Module (ECM) or Body Control Module (BCM). This mismatch can lead to persistent error codes, incorrect shift points, and even a no-start condition. Our mandatory VIN programming service ensures this module is a perfect digital match for your truck, guaranteeing all systems integrate seamlessly for optimal performance and reliability from the moment you install it.
Frequently Asked Questions
What does a Transmission Control Module do?
The TCM is the ‘brain’ of your automatic transmission. It uses data from various sensors to control shift solenoids, manage torque converter lockup, and regulate fluid pressure, ensuring smooth and efficient gear changes.
Is this module difficult to install?
Installation is straightforward for a DIYer with basic tools or any professional mechanic. The TCM is typically located in the engine bay (often next to the battery or under the air cleaner box) and can be replaced in under 30 minutes. Since it’s pre-programmed, no special electronic tools are needed.
How do I know for sure my TCM is the problem?
While the symptoms listed above are strong indicators, a proper diagnosis with a professional scan tool is the best way to confirm. Look for codes like P0700 or specific solenoid circuit faults. An erratic speedometer or gear indicator can also point to a failing TCM.
Will this part fit vehicles other than the 2007-2013 Sierra 1500?
Yes. This T42 TCM is compatible with a wide range of 2006-2014 GM vehicles, including the Silverado, Tahoe, Yukon, Express, Impala, and many more. Please check the detailed fitment list on this page to confirm compatibility with your specific model.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot ship the module without programming it, as an unprogrammed unit will not function in your vehicle. This critical step ensures you receive a fully functional, plug-and-play part.
Do I need to return my old part?
No, there is no core charge for this module. You can keep or dispose of your old part at your convenience, making the replacement process simple and hassle-free.
