HYDRAULIC CIRCUIT 7C
HYDRAULIC CIRCUIT
OUTLINE
The flow of the individual hydraulic circuits are identified as listed below.
(Numbers indicate individual circuits)
Line pressure source 7
Control element operation system line pressure.... 1,2,3,4,5,6,7,8,9,10,11,12
Auxiliary line pressure 13
Throttle system pressure 16,17,18,19
Governor system pressure 15
Torque converter system pressure 14
1. Line pressure
The line pressure is the hydraulic pressure of the oil emitted from the oil pump after adjustment
by the pressure regulator valve.
2. Throttle pressure
Derived from the line pressure, the throttle pressure is the hydraulic pressure generated by the throttle
valve which operates in conjunction with the intake manifold vacuum.
3. Governor pressure
Also derived from the line pressure, the governor pressure is the hydraulic pressure which varies
in conjuction with the vehicle's speed. It is controlled by the governor rotating together with the out-
put shaft.
