B Clutch Hydraulic Operation
Pump output pressure is supplied to the B (4, 6, R) clutch control valve. As SSB turns on, it moves the control valve allowing regulated pump output pressure to flow to the B (4, 6, R) clutch latch valve and than to the mechanical B (4, 6, R) clutch. When the regulated pump output pressure in the B (4, 6, R) clutch control circuit reaches approximately 100 psi, the mechanical B (4, 6, R) clutch is fully applied. The pressure in the B (4, 6, R) clutch control circuit moves the B (4, 6, R) clutch latch valve to the left which allows pump output pressure to hold the mechanical B (4, 6, R) clutch applied.
