Restore Flawless Shifting to Your Chevy Colorado
Is your 2008-2012 Chevy Colorado suffering from erratic shifting, getting stuck in gear, or throwing transmission codes? Don’t let a faulty Transmission Control Module (TCM) sideline your reliable truck. As a technician with over two decades of experience, I’ve seen countless GM trucks plagued by these exact issues. The culprit is almost always a failing TCM, the electronic brain that governs your automatic transmission’s every move. This replacement T42 TCM, part number 24235753, is the definitive, hassle-free solution to get your truck’s transmission operating like new again.
The biggest headache with replacing electronic modules is the need for dealership programming. We eliminate that completely. We pre-program this module to your truck’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives ready for a true plug-and-play installation, saving you time, towing fees, and the high cost of dealership service. This isn’t just a part; it’s a complete repair solution designed for both seasoned mechanics and first-time DIYers.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 GMC Canyon (the Colorado’s sibling) with a classic complaint: it was stuck in 3rd gear (limp mode) and had a P0700 code. They had already replaced two shift solenoids based on a forum suggestion, but the problem persisted. After a quick scan, I confirmed the P0700 but also saw communication loss codes with the TCM. In my shop, I’ve learned that intermittent power or communication faults in these T42 modules are common. Instead of chasing phantom solenoid issues, we installed a VIN-programmed TCM. The truck was shifting perfectly within an hour of its arrival. This simple swap saved the customer from a potential transmission rebuild and got them back on the road with confidence.
Is Your Colorado Exhibiting These Telltale Signs?
A failing TCM will give you clear warnings. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement. Ignoring these can lead to more severe transmission damage.
- âś” Harsh, jerky, or delayed gear shifts.
- âś” The truck refuses to shift out of a single gear (often called “limp mode”).
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Active Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- âś” A sudden drop in fuel economy.
- âś” The transmission seems to slip between gears or fails to engage properly from Park.
Quick & Easy TCM Installation Guide
Replacing the 2008-2012 Colorado TCM is a straightforward job you can do in your driveway in under 30 minutes. On these trucks, the module is conveniently located in the engine bay.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts and to help reset the system.
- Locate the TCM: Open the hood and find the TCM. On the 2008-2012 Colorado and Canyon, it’s typically mounted on the right-hand (passenger side) rear of the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical connectors, ensuring they click securely into place.
- Final Steps: Reconnect the negative battery terminal. Start the truck and allow it to idle for a few minutes. If you have a basic OBD2 scanner, it’s good practice to clear any stored codes. Take your truck for a test drive to confirm smooth shifting has been restored.

Frequently Asked Questions
Will I need to program this module at a dealership?
No. This is the biggest benefit we offer. We program the module to your vehicle’s VIN before shipping, so it arrives ready for immediate installation. It’s a true plug-and-play fix.
Will this 2008-2012 Colorado TCM fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the main engine computer. While a faulty TCM is a very common cause for this code, it’s essential to use a scanner that can read transmission-specific codes (e.g., P0753, P0758) to confirm the diagnosis. In many cases, replacing the TCM will resolve the root cause of the P0700.
