Direct (3, 5, R) Clutch Hydraulic Circuits

WARNING: This page is about a different car, the 2013 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

When the direct (3, 5, R) clutch is applied in REVERSE, LINE pressure from the pump is directed to the multiplex manual valve by the manual valve through the REV hydraulic circuit. The multiplex manual valve supplies the direct (3, 5, R) clutch regulator valve with pressure through the REV SUPPLY and C35R SUPPLY hydraulic circuits. To apply the direct (3, 5, R) clutch, SSB applies varying solenoid pressure to the C35R clutch regulator and boost valves. As the C35R regulator valve moves, it supplies the direct (3, 5, R) clutch and C35R boost valve with regulated line pressure through the C35R circuit. The C35R boost valve directs the regulated line pressure to the opposite side of the C35R clutch regulator valve through the C35R FDBK circuit for controlled direct (3, 5, R) clutch engagement.

When the direct (3, 5, R) clutch is applied in 3rd and 5th gears, LINE pressure from the pump is directed to the multiplex shift valve by the manual valve through the DRIVE 1 hydraulic circuit. The multiplex shift valve directs the pressure to the direct (3, 5, R) clutch regulator valve through the DRIVE 2/C35R SUPPLY circuits. To apply the direct (3, 5, R) clutch, SSB applies varying solenoid pressure to the C35R clutch regulator and boost valves. As the C35R regulator valve moves, it supplies the direct (3, 5, R) clutch and C35R boost valve with regulated line pressure through the C35R circuit. The C35R boost valve directs the regulated line pressure to the opposite side of the C35R clutch regulator valve through the C35R FDBK circuit for gradual direct (3, 5, R) clutch engagement.
