Is Your Chevy Colorado Transmission Acting Up?
If you’re dealing with a 2008-2012 Chevy Colorado that’s shifting hard, getting stuck in gear, or throwing transmission codes like P0700, you know how frustrating it can be. A faulty Transmission Control Module (TCM) is one of the most common culprits. As the transmission’s brain, when it fails, it can make your reliable truck feel unpredictable and unsafe. You might experience sudden, harsh shifts, a delay when putting it in drive, or the dreaded ‘limp mode’ that leaves you stuck on the side of the road.
A Real-World Scenario from My Shop
Just last month, a 2011 Colorado was towed in. The owner, a local contractor, was losing work because his truck would randomly refuse to shift out of 2nd gear. His scanner showed a P0752 (Shift Solenoid A Stuck On) and the generic P0700 code. We checked the wiring and solenoids, which were fine. The issue was internal to the TCMโa classic failure I’ve seen hundreds of times. Instead of a costly trip to the dealer, we installed one of our VIN-programmed T42 modules. In under an hour, the codes were gone, the truck was shifting perfectly, and he was back on the job. This is the exact fix for that exact problem.

Frequently Asked Questions (FAQ)
- How do I know for sure my TCM is failing?
- Common signs include erratic shifting, getting stuck in one gear (limp mode), a lit check engine or transmission warning light, and codes like P0700. If you’re experiencing several of these symptoms, the TCM is the most likely cause.
- Is any additional programming really required?
- No. We handle all the programming based on the VIN you provide during checkout. This ensures the module communicates perfectly with your truck’s engine computer and other systems without needing a trip to the dealer.
- Where is the TCM on my 2010 Chevy Colorado?
- It is located in the engine bay, specifically in the right-hand rear area of the compartment. This placement makes it accessible for a quick replacement.
- Will this fix a P0700 transmission code?
- Yes. The P0700 code is a general fault code indicating the TCM has detected a problem. Replacing a faulty TCM with this programmed unit will resolve the underlying issue, allowing you to clear the P0700 and any related codes for good.
- What if I have a GMC Canyon or Hummer H3?
- This T42 TCM is also the correct fit for the 2008-2012 GMC Canyon and 2008-2010 Hummer H3, as they share the same platform and transmission systems. It is also located in the RH rear engine compartment on those models.
