Is Your Pontiac G6 Shifting Erratically or Stuck in Limp Mode?
If you’re dealing with frustrating transmission issues in your 2006-2010 Pontiac G6, a faulty Transmission Control Module (TCM) is the most common culprit. Over my 20 years in the shop, I’ve seen hundreds of these T42 modules fail. The symptoms are always the same: the car suddenly refuses to shift, the check engine light pops on, and you’re left with a vehicle that feels unpredictable and unsafe. This isn’t just an inconvenience; it’s a critical failure that needs a reliable solution.
From the Shop Floor: A Real-World G6 Scenario
“A customer’s 2009 G6 came in last week with these exact symptomsโit was stuck in 3rd gear (limp mode) and throwing a P0700 code. The owner had already replaced a shift solenoid with no luck. We diagnosed the TCM and found internal circuit board damage from years of heat cycles under the hood. We installed one of our VIN-programmed modules, cleared the codes, and the car drove out of the bay shifting as smoothly as it did from the factory. This is a fix I’ve performed countless times, and it works every time.”
Symptoms of a Failing Pontiac G6 TCM
A bad transmission module can manifest in several ways. If you’re experiencing any of the following, it’s time to inspect your TCM:
- โ Harsh, slamming shifts or delayed gear engagement.
- โ Vehicle is stuck in one gear (often called “limp mode”).
- โ Check Engine Light or Transmission Warning Light is illuminated.
- โ Diagnostic Trouble Codes (DTCs) like P0700, P0753, P0758, or other solenoid-related faults.
- โ Complete loss of communication with the transmission module.
- โ Poor fuel economy and a feeling of sluggish performance.

Expert Pro Tip: Check Your Connectors
Before you install the new module, take a moment to inspect the vehicle’s harness connectors. Look for any signs of green or white corrosion on the pins, or any bent or damaged pins. A poor connection can mimic the symptoms of a failed TCM. Use a small amount of electrical contact cleaner and a soft brush to clean the terminals for a perfect connection.
