Restore Peak Transmission Performance in Your GM Truck or SUV
Is your 2008-2012 Chevrolet Colorado or GMC Canyon suffering from erratic shifting, getting stuck in gear, or displaying a check engine light with transmission codes? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating smooth gear changes, managing torque converter lockup, and ensuring overall drivetrain efficiency. When it fails, it can cripple your vehicle’s performance and reliability. This genuine quality GM T42 TCM, service number 24235340, is the definitive solution to restore your vehicle’s factory-perfect operation.
From the Diagnostic Bay
We had a 2010 Colorado come into the shop that was permanently stuck in 3rd gear—a classic ‘limp mode’ case. The customer was worried about a complete transmission rebuild. After a quick scan, we pulled a P0700 code, pointing to a general transmission fault. A deeper dive showed communication errors with the TCM. Instead of a costly mechanical repair, we installed one of these VIN-programmed T42 modules. In under 30 minutes, the truck was shifting perfectly through all gears, the check engine light was off, and the customer saved thousands. It’s a testament to how a targeted electronic component replacement can solve what seems like a catastrophic mechanical failure.
Signs You Need a 2008-2012 Colorado TCM
A failing TCM can manifest in various ways, often mimicking more severe mechanical issues. If you’re experiencing any of the following, your TCM is the likely culprit:
- ✔ Harsh, delayed, or unpredictable gear shifts that make driving uncomfortable.
- ✔ The vehicle refuses to shift out of a certain gear, commonly known as “limp mode.”
- ✔ An illuminated Check Engine Light or Transmission Warning Light on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- ✔ A noticeable decrease in fuel economy due to inefficient transmission operation.
- ✔ Complete failure to engage gears or move from a stop.

Simple Installation Process
For the 2008-2012 Chevrolet Colorado and GMC Canyon, the TCM is typically located in the right-hand rear of the engine compartment. The replacement process is straightforward: simply disconnect the vehicle’s battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect everything, and you’re ready to go. We recommend using a basic scan tool to clear any stored fault codes after installation to ensure a clean slate for the new module.
Frequently Asked Questions
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software, including shift strategies and communication protocols, onto the module. Without it, the TCM won’t be able to properly communicate with the engine computer and other vehicle systems, leading to continued shifting problems or a no-start condition. Our pre-programming service makes it a true plug-and-play solution.
Will this module fit vehicles other than the Colorado/Canyon?
Yes, the T42 hardware is used in a wide variety of GM vehicles like the Silverado, Tahoe, Impala, and more. However, the programming is vehicle-specific. This part will be programmed specifically for the VIN you provide at checkout, ensuring perfect function for your exact model.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, the installation is simple and takes less than 30 minutes. It involves disconnecting the battery, removing a few bolts, and swapping electrical connectors. The location on the 2008-2012 Colorado TCM is easily accessible in the engine bay.
Will this fix a P0700 diagnostic trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause that triggers a P0700, it’s essential to diagnose any other accompanying codes (like solenoid codes) to confirm the TCM is the primary point of failure.
Do I need to send my old module back?
No, there is absolutely no core charge or requirement to return your old part. You can dispose of it at your convenience.
