Electronic Component Description

The TCM gathers the vehicle operating information from the various sensors and controls listed below. The various sensors and controls are both internal and external to the transmission. The TCM processes this information and controls the following solenoids:
- Transmission shift points through the shift solenoids
- Transmission shift feel through the force motor solenoid
- TCC apply and release timing through the TCC control solenoid
- The brake band apply through the PWM band apply solenoid

Electronic control of these transmission operating characteristics provides consistent and precise shift points and shift quality based on the operating conditions of both the engine and the transmission.
