Frequently Asked Questions
Do I need to get this module programmed by a dealer?
No. This is the biggest benefit of our product. We program the transmission control module to your car’s specific VIN before we ship it. It arrives ready for a plug-and-play installation.
Where is the TCM located on my 2007-2010 Pontiac G5?
On the Pontiac G5, the transmission control module is typically located on the driver’s side of the engine compartment, mounted to the strut tower.
Will this part fix a P0700 trouble code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. While this module often resolves the root cause, it’s always best to have the specific secondary codes read (e.g., P0750, P0753) to confirm the diagnosis. A faulty TCM is a very common reason for these codes.
Is this installation difficult for a DIY mechanic?
The installation is generally straightforward and can be completed in under 30 minutes with basic hand tools. Simply disconnect the battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect everything and you’re done.
Is this compatible with other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of GM vehicles from 2006-2014 that use a 4-speed automatic transmission like the 4L60E or 4L65E. However, this specific listing is tailored for a perfect fit and program for the 2007-2010 Pontiac G5.
