GENERAL

The electronic hydraulic control system for transmission and transfer consists of various sensors, switches, TCM and control valve containing solenoid valves. This system controls shifting, lock-up clutch operation, line pressure and automatic transmission operation including shift timing. This also controls transfer clutch operation. TCM judges vehicle driving status based on various types of input signals and controls a total of eight solenoids (front brake solenoid, forward brake solenoid, input clutch solenoid, high & low reverse clutch solenoid, direct clutch solenoid, lock-up solenoid, line pressure solenoid and transfer solenoid) by sending appropriate signals.
