Frequently Asked Questions
Do I need to take my truck to a dealer after installation?
Absolutely not. Because we program the module to your vehicle’s VIN before shipping, it is a true plug-and-play part. Simply install it, connect your battery, and you’re ready to go. This process completely bypasses the need for dealership tools or programming fees.
Is this part difficult to install on my Colorado?
Installation is very straightforward for a DIY-er with basic tools. On the 2008-2012 Colorado and Canyon, the TCM is located in the right-hand rear of the engine compartment. The process typically takes less than 30 minutes. Just disconnect the battery, unplug the electrical connectors, unbolt the old module, and install the new one.
What does a transmission control module actually do?
The TCM is the ‘brain’ of your automatic transmission. It uses data from various sensors on the engine and transmission to control everything from when the gears shift and how firmly they engage to managing the torque converter. When it fails, the transmission loses its instructions, leading to poor performance.
Will this fit other vehicles besides the Colorado?
Yes, this T42 TCM is compatible with a wide range of 2006-2014 General Motors vehicles equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E. While this listing is focused on the 2008-2012 Colorado transmission control module, it also fits many Silverado, Tahoe, Yukon, and Express models. Please verify the part number for your specific application.
What happens if I don’t replace a bad TCM?
Continuing to drive with a faulty TCM can lead to more severe and expensive damage. Poor shifting can cause premature wear on clutches and bands inside the transmission, and incorrect line pressure can lead to overheating. A relatively simple electronic fix can prevent a complete transmission failure down the road.
