Overdrive (4, 5, 6) Clutch Hydraulic Circuits
To apply the overdrive (4, 5, 6) clutch, the manual valve must be in the NEUTRAL, DRIVE, M, 2 or 1 position to provide line pressure to the overdrive (4, 5, 6) clutch regulator valve through the NDX hydraulic circuit.
SSE provides regulated pressure from the SF hydraulic circuit to the overdrive (4, 5, 6) clutch regulator and latch valves through the PC5 and PC5Z hydraulic circuits to position the valves to apply the overdrive (4, 5, 6) clutch. As the overdrive (4, 5, 6) clutch regulator valve moves, it opens the NDX hydraulic circuit to the C456 circuit to supply regulated line pressure to the overdrive (4, 5, 6) clutch cylinder. For controlled overdrive (4, 5, 6) clutch engagement, the overdrive (4, 5, 6) clutch latch valve directs the regulated line pressure from the C456 circuit to the opposite side of the overdrive (4, 5, 6) clutch regulator valve through the CB456FB circuit.
The overdrive (4, 5, 6) clutch is applied in 4th, 5th and 6th gear.
