Low/Reverse Clutch Hydraulic Circuits
WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
To apply the low/reverse clutch, the manual valve can be in any position. Line pressure is supplied to the D1 regulator and latch valves through the PUMP circuit. SSD provides regulated solenoid pressure from the SREG circuit to the solenoid multiplex valve through the VFS4 circuit where it is directed to the D1 regulator and latch valves through the CL DC circuit to position the valves. The clutch D1 regulator valve provide regulated line pressure from the PUMP circuit to the CL D1 circuit to apply the low/reverse clutch.
