C Clutch Hydraulic Operation

Line pressure is supplied to the C clutch control valve and the C clutch latch valve. As SSC turns on, it moves the control valve allowing regulated line pressure to flow to the C clutch latch valve and then to the mechanical C clutch. When the regulated line pressure in the C clutch control circuit reaches approximately 689 kPa (100 psi), the mechanical C clutch is fully applied. The pressure in the C clutch control circuit moves the C clutch latch valve to the left which allows line pressure to hold the mechanical C clutch applied.
