Is Your Pontiac G5 Shifting Erratically or Stuck in Gear?
If you’re experiencing frustrating and unpredictable transmission behavior in your 2007-2010 Pontiac G5, a failing Transmission Control Module (TCM) is the most likely culprit. This critical component acts as the brain of your automatic transmission, managing everything from gear changes to torque converter clutch engagement. When it starts to fail, it can cause a cascade of problems, including harsh shifting, delayed gear engagement, poor fuel economy, and the dreaded check engine light. Don’t let a faulty module sideline your vehicle. This OEM-quality T42 TCM is the definitive solution, pre-programmed to your vehicle’s VIN for a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2008 Pontiac G5 come into the shop that the owner was ready to give up on. It would slam into gear from a stop and sometimes refuse to shift past 2nd gear, making highway driving impossible. The dashboard was lit up with a check engine light and a transmission warning. A quick scan showed a P0700 (Transmission Control System Malfunction) and several solenoid circuit codes. Instead of chasing down individual solenoids, our experience pointed directly to the TCM. After installing one of our VIN-programmed T42 modules, the car shifted like it just rolled off the factory floor. All codes were cleared and stayed cleared. It’s a common issue on these platforms, and a correctly programmed module is the key to a lasting fix.
Symptoms of a Failing Pontiac G5 TCM
- ✔ Harsh Shifting: Experiencing abrupt, jerky, or slamming gear changes that make driving uncomfortable.
- ✔ Stuck in Limp Mode: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) as a protective measure.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): Codes like P0700, P0750, or other transmission-related faults are stored in the computer.
- ✔ Delayed Engagement: A noticeable pause when shifting from Park into Drive or Reverse.
- ✔ Poor Fuel Economy: Inefficient shifting patterns cause the engine to work harder, consuming more fuel.
- ✔ Complete Transmission Failure: In severe cases, the vehicle may not move at all.
