Expert Insight: The T42 TCM Advantage
The T42 TCM used in the Pontiac G5 and similar GM platforms is a solid unit, but over time, heat cycles and vibrations can cause internal solder joints and electronic components to fail. This leads to the intermittent and frustrating issues you’re likely seeing. Many shops will simply replace the part, but that’s only half the battleโit still needs to be programmed. Our process handles that critical step for you. By programming it with your car’s VIN beforehand, we ensure all the unique software parameters for your specific vehicle are loaded and ready. It’s the smartest, most efficient way to perform this repair.
Frequently Asked Questions
What does ‘VIN Programmed’ actually mean for me?
It means the module is ready for installation right out of the box. We use your vehicle’s unique 17-digit Vehicle Identification Number (VIN) to load the exact software and calibrations from GM. This makes the module a true plug-and-play part, eliminating the need for any additional, expensive programming tools or a visit to the dealership.
Is this part difficult to install on my Pontiac G5?
No, this is a very straightforward repair for a DIYer with basic tools. On the 2007-2010 Pontiac G5, the TCM is conveniently located on the LH (driver’s side) strut tower in the engine bay. The entire process typically takes less than 30 minutes. Just remember to disconnect the battery before you begin.
Will this fix my transmission error codes like P0700?
Yes. A P0700 code is a general fault code indicating the TCM has detected a problem. By replacing the faulty module with this correctly programmed unit, you are addressing the root cause of the code and other related transmission DTCs. After installation, you can clear the codes with a standard scan tool.
Do I need to send my old part back?
No core charge is required for this part. You can keep your old module, recycle it, or dispose of it at your convenience. This makes the process faster and hassle-free for you.
Is this compatible with other GM vehicles?
Absolutely. While this listing is for the 2007-2010 Pontiac G5 transmission control module, this T42 module is used across a wide range of GM vehicles, including the Chevrolet Cobalt, HHR, Saturn Ion, and many others. The key is our VIN programming, which customizes it for your specific make and model.
