Kia Rio: Transaxle Control Module (TCM) Description
Transaxle Control Module (TCM) is the automatic transaxle's brain. The
module receives and processes signals from various sensors and implements a
wide range of transaxle 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 transaxle failure or malfunction, TCM stores the fault information
in memory so that the technician may reference the code and quickly repair the
transaxle.
