  Sensors and solenoid valves Function
Input Park/neutral position (PNP) switch Detects select lever position and sends a signal to TCM.
Throttle position sensor [accelerator pedal position (APP) sensor] Detects accelerator pedal position and requested throttle opening and sends a signal to TCM.
Engine speed signal Receives signal from ECM and controls lock-up control solenoid valve.
A/T fluid temperature sensor Detects transmission fluid temperature and sends a signal to TCM.
Revolution sensor Detects output shaft rpm and sends a signal to TCM.
Vehicle speed sensor Used as an auxiliary vehicle speed sensor. Sends a signal which is used if revolution sensor (installed on transmission) malfunctions.
Overdrive control switch Sends a signal to the TCM which prohibits a shift to D4 (overdrive) position.
ASCD control unit Sends the cruise signal and D4 (overdrive) cancellation signal from ASCD control unit to TCM.

Output Shift solenoid valve A/B Selects shifting point suited to driving conditions in relation to a signal sent from TCM.
Line pressure solenoid valve Regulates line pressure suited to driving conditions in relation to a signal sent from TCM.
Torque converter clutch solenoid valve Regulates lock-up pressure suited to driving conditions in relation to a signal sent from TCM.
Overrun clutch solenoid valve Controls an "engine brake" effect suited to driving conditions in relation to a signal sent from TCM.
O/D OFF indicator lamp Shows TCM faults, when A/T control components malfunction.
CAN communication Control units are connected to two communication lines (CAN H and CAN L) allowing a high rate of information transmission.
