Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that acts as the brain for your automatic transmission. It receives data from various sensors on the engine and vehicle, and uses that information to control when the transmission shifts gears, how firm the shifts are, and when the torque converter locks up for better fuel economy.
Is this TCM difficult to install?
For most 2006-2011 Impala models, the TCM is located in the engine compartment, often near the air cleaner housing, making it accessible. Installation typically takes less than 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.
Do I need to go to the dealer for programming after installation?
No. The main benefit of this part is that we program it to your vehicle’s VIN before we ship it. This means it is ready to install right out of the box, saving you the time, cost, and hassle of a dealership visit for programming.
How do I know for sure if my TCM is failing?
Common signs include erratic shifting, the vehicle going into limp mode, and specific transmission-related diagnostic codes (like P0700). While other issues can cause similar symptoms, a faulty TCM is a very common cause for these problems on GM vehicles of this era.
What happens if I don’t provide my VIN when I order?
Providing your VIN is essential for the programming process. Without it, we cannot program the module to match your vehicle’s specific configuration, and the part will not function correctly. Please be sure to enter your VIN accurately during checkout to ensure a smooth, plug-and-play installation.
