Frequently Asked Questions
What is a Transmission Control Module (TCM)?
The TCM is the electronic brain of your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses that information to control gear shifts, torque converter lockup, and line pressure for smooth and efficient operation.
Is this part difficult to install?
For the Pontiac G6, the TCM is typically located on the LH strut tower, making it accessible. With basic hand tools, most DIY mechanics can complete the installation in under 30 minutes. Simply disconnect the battery, unplug the old module, install the new one, and reconnect the battery. We recommend using a scan tool to clear any stored codes after installation.
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, making the process simple and hassle-free.
How do I know this is the right part for my car?
This module, part number 24234274, is a direct fit for the 2006-2010 Pontiac G6. It is also interchangeable with other service numbers listed in the product details. Providing your VIN at checkout guarantees we program the correct Pontiac G6 transmission control module for your specific vehicle.
Will this fix my P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the underlying issue causing the P0700, it’s always wise to scan for more specific codes (like P0750, etc.) to confirm the diagnosis. A failing TCM is the most common cause.
