Is Your Colorado Shifting Erratically or Stuck in Limp Mode?
Dealing with transmission problems in your 2008-2012 Chevy Colorado can be incredibly frustrating. Whether you’re experiencing harsh, delayed shifts, the truck refusing to shift out of a certain gear, or a persistent check engine light, a faulty Transmission Control Module (TCM) is often the culprit. Ignoring these symptoms can lead to more significant transmission damage and leave you stranded. This VIN-programmed T42 TCM is the definitive solution to get your truck’s transmission operating smoothly and reliably again.
Common Symptoms & Your Solution
If your truck is showing any of these signs, it’s time to replace your TCM. This module is the direct fix for:
- Harsh, jerky, or erratic shifting between gears
- The vehicle being stuck in “limp mode” (usually 2nd or 3rd gear)
- Transmission or Check Engine warning lights on the dash
- Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes
- Failure to upshift or downshift properly
- Poor fuel economy and potential transmission overheating
By installing our expertly programmed 2008-2012 Colorado transmission control module, you directly address the root cause of these electronic failures, restoring factory performance without a trip to the dealership.

Frequently Asked Questions
Will this TCM need to be programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s exact VIN before shipping it to you. This makes the installation plug-and-play, saving you hundreds of dollars and a trip to the dealership.
Where is the TCM located on a 2008-2012 Colorado?
On the Chevrolet Colorado and GMC Canyon from this era, the Transmission Control Module is typically located in the engine compartment on the right-hand (passenger) side, towards the rear of the compartment.
Is this part difficult to install myself?
For someone with basic mechanical skills, this is a straightforward job. It usually involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and then reversing the process. The entire job typically takes less than 30 minutes.
How do I know for sure that my TCM is the problem?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and specific diagnostic codes like P0700 (Transmission Control System Malfunction). If you are experiencing these electronic symptoms, the TCM is the most likely cause. A faulty TCM often causes issues that seem like a major mechanical failure.
What happens if I don’t replace a failing TCM?
Continuing to drive with a bad TCM can cause poor fuel economy, unsafe driving conditions (like delayed or no shifting), and can eventually lead to permanent mechanical damage to your transmission due to incorrect fluid pressures and shift commands.
Does this 2008-2012 Colorado transmission control module come with a warranty?
Yes, this part is covered by our one-year replacement warranty, giving you confidence in your repair.
