Intermediate Clutch (C) 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 intermediate clutch, the manual valve can be in the DRIVE, 3, 2 or 1 position to provide line pressure to the clutch C regulator valve through the DRIVE circuit. SSC provides regulated solenoid pressure from the SREG circuit to the clutch C regulator valve through the VFS3 circuit to position the valve to apply the intermediate clutch). As the intermediate clutch is applied, SSC increases pressure to the clutch C regulator valve. The clutch C regulator valve provides regulated line pressure to the CL C circuit to apply the intermediate clutch. In 6th gear, regulated solenoid pressure from the clutch E latch valve is supplied to the clutch C regulator valve through the VFS3E circuit. VFS3E opposes VFS3 pressure. This action effectively reduces the amount of VFS3 force acting on the regulator valve and results in a smooth shift into 6th gear.
