Intermediate (2, 6) Clutch Mechanical Operation

The intermediate clutch is a brake clutch that holds the rear sun and shell assembly. The intermediate clutch is applied in 2nd and 6th gear.

Hydraulic pressure from the regulator valve in the valve body pushes the intermediate clutch piston against the intermediate clutch pack to apply the clutch. The rear planetary sun gear is held stationary to the transmission case as a result of the clutch being applied.

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 Shift Solenoid C (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 controlled 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 Shift Solenoid C (SSC) solenoid pressure.
