Is Your GMC Canyon Experiencing Transmission Troubles?
If your 2008-2012 GMC Canyon is suffering from harsh shifting, delayed gear engagement, or has suddenly entered a frustrating ‘limp mode,’ a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it starts to fail, it can cause a host of drivability issues, from poor fuel economy to a complete inability to shift gears, often accompanied by a check engine light and transmission-related diagnostic trouble codes (DTCs).
From the Diagnostic Bay
We recently had a 2011 GMC Canyon towed in that was stuck in 3rd gear. The owner was worried about a catastrophic transmission failure. After a quick scan, we pulled a P0700 code (Transmission Control System Malfunction) along with several solenoid circuit codes. Instead of quoting a costly internal transmission repair, we identified the root cause: a faulty TCM. We installed one of our VIN-programmed T42 modules, cleared the codes, and had the truck shifting perfectly on the test drive. The customer was back on the road in under an hour, avoiding an expensive and unnecessary trip to the dealership.
The Plug-and-Play Solution for Your Transmission
Don’t let a faulty module sideline your truck. This OEM-quality T42 Transmission Control Module, service number 24235732, is the definitive solution. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates flawlessly with your Canyon’s powertrain control module (PCM) and other systems right out of the box. No additional flashing or expensive programming tools are required. It’s a true plug-and-play fix that restores the smooth, reliable performance you expect from your vehicle.
Signs You Need a New 2008-2012 Canyon TCM
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your drive.
- ✔ Your truck is stuck in one gear (often called ‘limp mode’) and will not upshift or downshift.
- ✔ The check engine light or transmission warning light is illuminated on your dashboard.
- ✔ Diagnostic scans reveal codes like P0700, P0750, or other solenoid-specific faults.
- ✔ A noticeable decrease in fuel efficiency or signs of the transmission overheating.
- ✔ Complete loss of communication with the transmission module, leading to a no-start or no-shift condition.

Frequently Asked Questions
What does a Transmission Control Module do on my GMC Canyon?
The TCM acts as the computer for your automatic transmission. It processes data from various sensors (like vehicle speed and engine load) to control shift solenoids, regulate fluid pressure, and manage the torque converter, ensuring smooth and efficient gear changes.
Do I need to program this module after installation?
No. This module comes pre-programmed to your vehicle’s specific VIN. This makes the installation process simple and straightforward, as it is ready to be installed right out of the box without needing a trip to the dealership for expensive programming.
Is installing this 2008-2012 Canyon TCM a difficult job?
For most individuals with basic mechanical skills, this is a very manageable repair. The module is located in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It typically takes less than 30 minutes.
Will this part fix a P0700 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 of a P0700 code (especially when paired with other solenoid or communication codes), you should always ensure other potential issues like wiring or solenoids have been checked. In many cases, a faulty TCM is the primary issue.
Where is the TCM located on my 2008-2012 GMC Canyon?
On the 2008-2012 GMC Canyon and its counterpart, the Chevrolet Colorado, the Transmission Control Module is typically found in the engine compartment, on the right-hand (passenger) side, towards the rear.
