Frequently Asked Questions
What does a transmission control module do on my GMC Canyon?
The TCM is a computer that receives data from various sensors on the engine and transmission. It uses this information to control exactly when the transmission shifts gears, when the torque converter locks up, and to monitor the overall health of the transmission, ensuring optimal performance and fuel efficiency.
Is this module difficult to install?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old module, unbolting it, and installing the new one in its place. On the 2008-2012 Canyon, it’s located on the right-hand rear side of the engine compartment. The entire process usually takes under 30 minutes.
What happens if I install a TCM that isn’t programmed to my VIN?
An un-programmed or incorrectly programmed TCM will likely not work at all, or it will cause severe shifting problems, incorrect speedometer readings, and persistent check engine lights. It will not be able to communicate properly with the Engine Control Module (ECM) and other vehicle systems. Our VIN programming service eliminates these issues entirely.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code, meaning the TCM has detected a problem and has requested the Check Engine Light to be turned on. While a faulty TCM can cause a P0700, this code is often accompanied by other, more specific codes. This module will fix the issue if the TCM itself is the source of the failure triggering the P0700 and other related codes.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module at your convenience, which simplifies the repair process for you.
