Valve Body: Description and Operation
System Pressure Control Valve
Valves are illustrated in their positions when the selector lever is set to neutral.
This valve opens when pressure reaches a certain level and the fluid is led back to the suction side of the pump. This valve functions as a variable
pressure limiting valve and works in relation to modulator pressure.
Throttle pressure controls system pressure via modulator pressure. The torque converter is fed with system pressure via a restriction. System pressure is
limited by a pressure relief valve in the pump housing.
