The operation of the transaxle is controlled by the powertrain control module. Many input sensors provide information to the PCM. The PCM then controls the actuators which affect transaxle operation.

The PCM controls the operation of the transaxle through wiring to the solenoid valve body assembly mounted on the main control assembly. An electrical connector from the solenoid valve body assembly fastens to the top of the transaxle case, where it connects to PCM wiring. The solenoid valve body assembly is serviced as one part when any new components are installed.
