Is Your Pontiac G6 Shifting Erratically or Stuck in Gear?
If you’re dealing with the frustration of a Pontiac G6 that slams into gear, refuses to shift, or has the check engine light glaring at you, a failing Transmission Control Module (TCM) is the most likely culprit. Over my 20+ years in automotive diagnostics, I’ve seen this exact scenario countless times. The TCM is the brain of your automatic transmission, and when it fails, it can make your daily drive unpredictable and stressful.
A Technician’s Real-World Experience
“A customer’s 2008 Pontiac G6 came in last week with these exact symptoms: harsh 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode). The scanner showed a P0752 code for a stuck shift solenoid. After confirming the solenoid itself was fine, we identified the root cause: a faulty TCM. These modules, especially the T42 generation, are known to develop internal circuit failures over time, leading to incorrect commands being sent to the transmission. Replacing the module with a properly programmed unit resolved all the issues instantly.”
The Direct Solution: A VIN-Programmed G6 Transmission Control Module
Don’t let a faulty module sideline your car. This OEM-quality T42 TCM, part number 24235732, is the definitive fix for your 2006-2010 Pontiac G6. The most significant benefit is that we program it to your vehicle’s specific VIN before shipping. This means it arrives at your door ready for a true plug-and-play installation, saving you from a costly and time-consuming trip to the dealership for programming.
Key Symptoms This Part Corrects:
- โ Harsh, jerky, or delayed gear shifts.
- โ Vehicle stuck in a single gear (limp mode).
- โ Check Engine Light or Transmission Warning Light on the dash.
- โ Diagnostic Trouble Codes (DTCs) such as P0700, P0750-P0758, or other solenoid-related faults.
- โ Poor acceleration and decreased fuel economy.
- โ Complete loss of communication with the transmission.
Expert Pro Tip: Check the Harness First!
On the Pontiac G6, the TCM is located on the driver’s side strut tower. Before condemning the module, take 60 seconds to inspect the wiring harness leading to it. I’ve seen cases where the harness rubs against the strut tower or battery tray, causing wires to chafe and short out. This can mimic the exact symptoms of a failed TCM. A quick visual inspection can save you from a misdiagnosis.
Plug-and-Play Installation: No Dealer Visit Required
You can have your G6 back to shifting smoothly in under 30 minutes with basic hand tools. This G6 Transmission Control Module is designed for a straightforward DIY replacement.
- Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts and to help reset the system.
- Locate the TCM: Open the hood and find the module mounted to the driver’s side (LH) strut tower. It’s a silver box with two large electrical connectors.
- Disconnect and Remove: Carefully unclip the two wiring harness connectors. Then, remove the bolts or nuts holding the module to its bracket.
- Install the New Module: Mount your new, pre-programmed TCM in the same location and securely reconnect the two wiring harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. While the module is pre-programmed, it’s always a good practice to use a basic scan tool to clear any stored DTCs from the vehicle’s memory.
