Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles like your Colorado, the TCM doesn’t just control the transmission—it communicates constantly with the Engine Control Module (ECM), Anti-lock Brake System (ABS), and other vehicle systems. A generic, non-programmed module can’t speak this unique language, leading to persistent codes, poor performance, or even complete incompatibility. Our VIN-specific programming ensures that your new TCM is a perfect digital match for your truck, guaranteeing seamless integration and optimal function from the moment you plug it in. This is the key to a successful, headache-free repair.
Don’t let a faulty TCM sideline your truck.

Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that acts as the brain for your automatic transmission. It collects data from various sensors in the engine and transmission to control shift timing, gear selection, and torque converter lockup, ensuring smooth and efficient operation.
Is this part difficult to install?
For the 2008-2012 Colorado and Canyon, the TCM is typically located in the right-hand rear of the engine compartment. With basic hand tools, installation usually takes under 30 minutes. Since this module is pre-programmed to your VIN, there is no complex software setup required, making it a very DIY-friendly repair.
Will this module 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 underlying issue causing the P0700, it’s always wise to have the specific transmission codes read with a quality scanner to confirm the diagnosis. This part is designed to fix internal TCM failures that trigger these codes.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module without any additional charges or hassle.
How do I provide my vehicle’s VIN for programming?
Typically, you will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. It is crucial to provide the correct VIN to ensure the module is programmed perfectly for your specific vehicle configuration.
Does this fit other GM vehicles besides the Colorado?
Yes, this T42 TCM is compatible with a wide range of GM vehicles from 2006-2014, including the GMC Canyon, Hummer H3, and various Silverado, Tahoe, and Express models. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
