Frequently Asked Questions
What does this T42 Transmission Control Module do?
The TCM acts as the brain for your automatic transmission. It receives data from various sensors on the vehicle and uses that information to control gear shifts, torque converter lockup, and line pressure for smooth and efficient operation.
Is this part really ‘plug and play’ for my Pontiac G6?
Yes. During checkout, you will provide your vehicle’s VIN. We use that information to program the module specifically for your car. This ensures it communicates correctly with your vehicle’s systems upon installation, with no further programming needed.
How do I know for sure that my TCM is the problem?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and specific transmission-related error codes (like P0700). While other issues can cause similar symptoms, a faulty TCM is a very common cause for these problems in GM vehicles of this era.
Where is the TCM located on a 2006-2010 Pontiac G6?
On the Pontiac G6, the Transmission Control Module is typically located on the driver’s side of the engine compartment, mounted to the LH strut tower. Always disconnect the battery before beginning the replacement.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module at your convenience, making the repair process simpler and hassle-free.
