Forward 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 forward clutch, the manual valve must be in the DRIVE, 3, 2 or 1 position to provide line pressure to the clutch A regulator valve through the DRIVE circuit.
For the forward clutch to apply, SSA provides regulated solenoid pressure from the SREG circuit to the clutch A regulator and latch valves through the VFS1 circuit to position the valves.
The clutch A regulator valve provides regulated line pressure to the CL A circuit to apply the forward clutch.
