SSD supplies pressure to the solenoid multiplex valve through the VFS4 circuit.

The position of the solenoid multiplex valve allows pressure from the VFS4 circuit to be directed to the D1 and D2 latch and regulator valves through the CL DC circuit to position the valves for low/reverse clutch (D) application.

Clutch hydraulic circuits:

Line pressure is supplied by the pump to the D1 latch and regulator valves.

Regulated line pressure from the D1 regulator valve is supplied to the low/reverse clutch (D) to apply the clutch.
