Restore Peak Performance to Your Pontiac G5’s Transmission
Are you experiencing frustrating and unpredictable shifting in your 2007-2010 Pontiac G5? Issues like harsh gear changes, getting stuck in limp mode, or an illuminated check engine light can point directly to a failing Transmission Control Module (TCM). This critical component is the brain of your automatic transmission, and when it malfunctions, it can disrupt your entire driving experience. This VIN-programmed T42 TCM is the definitive solution, engineered to restore the smooth, reliable performance your vehicle had when it was new.
Expert Pro Tip
Before you begin the installation, always disconnect the negative terminal of your vehicle’s battery. This not only ensures your safety but also helps reset the vehicle’s powertrain control module (PCM) and related systems. After installing the new TCM, reconnect the battery. This simple step can help clear adaptive memory and allow the vehicle’s systems to properly recognize the new module, ensuring a smoother initial drive cycle.
Is Your Pontiac G5 Exhibiting These TCM Failure Symptoms?
- ✔ Erratic and Harsh Shifting: Your car may bang into gear, hesitate between shifts, or feel generally unpredictable.
- ✔ Stuck in Gear / Limp Mode: The transmission may refuse to shift out of a single gear (often 2nd or 3rd) to prevent further damage.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): A scan tool reveals codes such as P0700 (Transmission Control System Malfunction), or specific solenoid codes like P0750, P0751, etc.
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter lockup caused by a faulty TCM can lead to a noticeable decrease in MPG.
- ✔ No Communication: In severe cases, a scan tool may be unable to communicate with the TCM at all, indicating a complete module failure.

Simple, Straightforward Installation
For the 2007-2010 Pontiac G5, the TCM is conveniently located at the driver’s side (LH) strut tower in the engine compartment, making access relatively simple. The replacement process can typically be completed in under 30 minutes with basic hand tools. Simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Once installed, reconnect the battery and use a basic OBD2 scanner to clear any stored fault codes. Best of all, there is no core charge—you can keep or dispose of your old part without any hassle.
What exactly does the Transmission Control Module do?
The TCM acts as the central computer for your automatic transmission. It collects data from various sensors (like vehicle speed, engine RPM, and throttle position) to determine the perfect moment to shift gears, control hydraulic pressure, and manage the torque converter lockup clutch for optimal performance and fuel efficiency.
Do I need to take my car to a dealer for programming after installation?
No. This module comes pre-programmed to your vehicle’s specific VIN. This plug-and-play solution saves you the time, cost, and hassle of a dealership visit, allowing you to complete the repair yourself.
Will this module fit other GM vehicles?
Yes, the T42 TCM hardware is used in a wide range of GM vehicles from 2006-2014, including models like the Chevrolet Cobalt, HHR, GMC Sierra, and Buick LaCrosse. However, the programming is vehicle-specific. This unit will be programmed precisely for your 2007-2010 Pontiac G5.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module will often resolve the root cause of the P0700, it’s always wise to scan for any other specific codes (e.g., solenoid or sensor codes) to confirm the TCM is the primary point of failure.
Is there a warranty included with this part?
Yes, this part comes with a one-year warranty, giving you peace of mind and assurance in the quality and reliability of your repair.
