What are the main signs of a bad TCM in a GMC Canyon?
The most common symptoms include harsh or erratic shifting, the truck getting stuck in limp mode (usually 3rd gear), the check engine light coming on with transmission-related codes (like P0700), and poor fuel economy.
Where is the TCM located on a 2008-2012 GMC Canyon?
On the 2008-2012 GMC Canyon, the transmission control module is typically located in the engine compartment, on the right-hand (passenger) side, towards the rear.
Is this a difficult part to install myself?
For someone with basic mechanical skills and tools, this is a very manageable job. It typically involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire process often takes less than 30 minutes.
What could happen if I keep driving with a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe transmission damage. Poor shifting can cause excessive wear on internal components like clutches and bands, potentially leading to a much more expensive mechanical repair down the line.
