LESSON 3: POWERTRAIN

Transmission Electronic System

The TCM receives input signals from certain transmission-related sensors and switches. The TCM uses these

signals to control the following operations:

•

Shift timing

•

Line pressure (shift feel)

•

Torque converter clutch

To accomplish this, the TCM uses six pressure control solenoids and one shift solenoid to control transmission

operation. Five pressure regulators and one solenoid valve are used to control direct transmission fluid flow to

select internal clutches and control the fluid pressure at the clutch. A separate pressure regulator is used

exclusively for torque converter clutch control.

The following provides a brief description of each of the sensors and actuators used to control transmission

operation.
