Description And Operation: Description: Notes
Transmission Control Module (TCM) is the automatic transmission's brain. The module receives and processes signals from various sensors and implements a wide range of transmission controls to ensure optimal driving conditions for the driver.
TCM is programmed for optimal response to any on-road situation. In the event of a transmission failure or malfunction, TCM stores the fault information in memory so that the technician may reference the code and quickly repair the transmission.
Component location: Mounted with the ECM on the top right side of the engine compartment.
