F Clutch Hydraulic Operation

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