Intermediate (2, 6) Clutch Hydraulic Circuits
When the intermediate (2, 6) clutch is applied in 2nd and 6th 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 supplies the intermediate (2, 6) clutch regulator valve with pressure through the DRIVE 2 and CB26FD/CB1234FD hydraulic circuits. The intermediate (2, 6) clutch regulator valve is controlled by SSC and directs regulated pressure to the intermediate (2, 6) clutch through the CB26 hydraulic circuit. The CB26 hydraulic circuit also supplies pressure to the opposite side of the CB26 clutch regulator valve for gradual intermediate (2, 6) clutch engagement. Regulated overdrive (4, 5, 6) clutch pressure is supplied to the intermediate (2, 6) clutch regulator valve in 6th gear to boost the SSC solenoid pressure.
When the intermediate (2, 6) clutch is released in 1st, 3rd, 4th and 5th gears, CB26FD/CB1234FD pressure is supplied to the intermediate (2, 6) clutch regulator valve. Solenoid pressure is not applied to the intermediate (2, 6) clutch regulator valve and the regulator valve blocks the CB26FD/CB1234FD circuit in this position.
