Pressure Regulation

WARNING: This page is about a different variant/trim than selected.

VFS Clutch Control Solenoid D 

Drive\reverse solenoid signal (25) fluid pressure is ramped up by the VFS clutch control solenoid D duty cycle and is routed to the clutch regulator valve.

Clutch Regulator Valve 

Increased pressure drive\reverse solenoid signal (25) fluid is routed thru orifice #40 to the clutch regulator valve and opposes valve spring force, allowing pressurized feed limit (23) fluid into the drive\reverse regulator (19) fluid circuit.
