Transfer Oil Pressure Control Device
The transfer control valve body is bolted the rear end of transmission case through transfer valve plate.
Hydraulic pressure used in the transfer valve body (line pressure and pilot pressure) are supplied from the transmission control valve body through the transmission case.
The transfer duty solenoid modulates the pilot pressure into the transfer duty pressure depending on the signals from transmission control module (TCM).
The transfer duty pressure in turn modulates the line pressure into the transfer clutch pressure before it is sent to the transfer control valve.
The transfer clutch pressure puts the transfer clutch into engagement depending on the driving conditions so that the optimum torque may be distributed to the rear wheels.
