Legacy Wagon 4WD F4-2.5L DOHC (1996)
1. The line pressure regulated to a proper pressure corresponding to the driving condition is further regulated to a constant pilot pressure by the
transfer pilot valve.
2. The pilot pressure is regulated to the transfer duty pressure by the duty solenoid c whose duty ratio is controlled by the Transmission Control
Module (TCM) corresponding to the driving condition. (The transfer duty pressure varies with the degree of duty control.)
3. The transfer duty pressure is applied to the transfer control valve.
4. The line pressure is led also to the transfer control valve where the pressure is regulated to the transfer clutch pressure by the transfer duty
pressure. (The transfer clutch pressure varies with the transfer duty pressure.)
5. The transfer clutch pressure is applied to the transfer clutch and causes the clutch to be engaged. In this way, the transfer clutch pressure is varied
so that optimum rear torque distribution can be achieved which corresponds to the vehicle driving conditions.
