Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is the electronic brain of your automatic transmission. It uses data from various sensors on the engine and transmission to control shift solenoids, regulate fluid pressure, and ensure smooth, efficient gear changes for optimal performance and fuel economy.
Is this module difficult to install?
For the Pontiac G5, the TCM is typically located on the driver’s side strut tower, making it very accessible. Installation is straightforward for someone with basic mechanical skills and tools, often taking less than 30 minutes. Simply disconnect the battery, unplug and unbolt the old module, install the new one, and reconnect the battery.
Will I need to go to the dealer after installing this part?
No. The most significant benefit of this module is that it comes pre-programmed to your vehicle’s VIN. This means no additional programming or flashing is required. It is a true plug-and-play solution, saving you time and money.
How do I know for sure if my TCM is failing?
Common symptoms include harsh shifting, getting stuck in one gear (limp mode), and a check engine light with transmission-specific codes (like P0700). A professional diagnosis is always best, but these signs strongly point to a faulty TCM.
What happens if I don’t replace a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe and expensive mechanical damage to your transmission. Poor shifting can cause excessive wear on clutches and bands, and incorrect fluid pressure can lead to overheating, eventually resulting in a complete transmission failure.
Does this part fit other GM vehicles?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 GM vehicles, including models from Chevrolet, GMC, Buick, Saturn, and Cadillac. However, this specific listing is tailored for the 2007-2010 Pontiac G5 to ensure you receive the correct programming for your vehicle.
