Restore Your Truck’s Drivability with a Plug-and-Play TCM
If your 2008-2012 Chevrolet Colorado is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most common cause. Over my 20+ years in the bay, I’ve seen countless trucks sidelined by what seems like a major transmission failure, when the real issue was this small electronic module. This replacement T42 TCM, part number 24235754, is the definitive, reliable fix. It arrives pre-programmed to your truck’s specific VIN, making it a true plug-and-play solution that eliminates the need for a costly trip to the dealership for programming.
As the brain of your 4L60E or similar 4-speed automatic transmission, the TCM governs every shift, manages torque converter lockup for fuel efficiency, and monitors the system for faults. When it fails, you get the frustrating symptoms that make your truck feel unpredictable and unsafe. This module restores that crucial communication, giving you back the smooth, reliable performance you depend on, whether you’re on a job site or just running errands. Don’t let a faulty module trick you into thinking you need a new transmission—fix the real problem with this dependable 2008-2012 Colorado TCM.
From the Diagnostic Bay: The “Bad Solenoid” That Wasn’t
A customer brought in a 2011 Colorado, stuck in 3rd gear (limp mode) with a P0753 (Shift Solenoid ‘A’ Electrical) code. He’d already replaced the solenoid inside the transmission pan, but the problem persisted. He was convinced the transmission was shot. I hooked up my professional scan tool and watched the live data. The computer was commanding the shift, but the solenoid wasn’t responding. Instead of tearing into the transmission again, I checked the TCM connector. After confirming the wiring was good, we knew the fault was internal to the module. The driver circuit inside his original TCM had burned out—a very common failure point. We installed one of our VIN-programmed modules, cleared the codes, and the truck was shifting perfectly in 20 minutes. He saved over a thousand dollars by correctly diagnosing the TCM instead of condemning the transmission.
Is Your Chevy Colorado Showing These Transmission Warning Signs?
- ✔️ Harsh, slamming shifts or delayed gear engagement.
- ✔️ Vehicle is stuck in “limp mode” and won’t shift out of 2nd or 3rd gear.
- ✔️ Check Engine Light or Transmission Warning Light is on.
- ✔️ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, P0753, P0758, or other solenoid-related faults.
- ✔️ Poor fuel economy and a feeling of sluggish performance.
- ✔️ Complete loss of communication with the transmission module (no gear indicator on the dash).
DIY Installation: Get Your Colorado Shifting Right in Under 30 Minutes
Replacing the 2008-2012 Colorado TCM is a straightforward job that most DIYers can handle with basic tools. No complex procedures or dealership visits are required.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts and to help reset the system.
- Locate the Module: On the 2008-2012 Colorado and its sibling, the GMC Canyon, the TCM is located in the engine compartment on the right-hand (passenger) side, toward the rear of the bay.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely plug in the electrical connectors until they click.
- Final Steps: Reconnect the battery terminal. Start the vehicle and allow it to idle for a few minutes. If you have a basic scan tool, use it to clear any stored codes. Take the truck for a test drive to confirm smooth shifting.

Frequently Asked Questions
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and calibrations onto the module before it ships. This ensures it communicates perfectly with your engine computer and other systems, just like the original part. It makes the installation plug-and-play and avoids expensive dealer programming fees.
Is this part difficult to install myself?
Not at all. For a 2008-2012 Colorado, it’s one of the easier electronic repairs. With basic hand tools, you can locate it in the engine bay and swap it out in under 30 minutes. Our step-by-step guide walks you through it.
Will this fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the main engine computer to turn on the check engine light. The actual problem is a more specific code stored in the TCM itself (like a solenoid or sensor code). If the root cause is a faulty TCM, then yes, replacing it will resolve the P0700 and the underlying codes.
Is there a core charge for my old part?
No, we do not require a core return. You can keep your old module, which saves you the time, hassle, and expense of shipping it back.
What kind of warranty is included?
This module is backed by our one-year warranty, giving you peace of mind that you’re installing a quality, reliable part that is built to last.
