In the 2012 Chevy Impala, you can find the TCM, which stands for transmission control module, located on top of the transmission. It's easily accessible from the engine bay under the hood, situated towards the front and passenger's side of the vehicle. To remove it, you would need to use an 8mm and 10mm sockets. The TCM plays a crucial role in managing how the car shifts gears by utilizing information from various sensors in the engine, such as the throttle position sensor, rotary speed sensor, and coolant temperature sensor. This unit is also responsible for sending OBD-II error codes to the car's main computer, which triggers the "check engine" light. If the TCM starts to malfunction, you may experience issues like rough shifting, being stuck in a gear, warning lights coming on, and a decrease in fuel efficiency. The average cost to replace the TCM in a Chevy Impala typically ranges from $550 to $600 for parts and labor.
