A Clutch Hydraulic Operation
Line pressure is supplied to the A clutch control valve and the A clutch latch valve. As SSA
turns on, it moves the control valve allowing regulated line pressure
to flow to the A clutch latch valve and then to the mechanical A clutch.
When the regulated line pressure in the A clutch control circuit
reaches approximately 698 kPa (100 psi), the mechanical A clutch is
fully applied. The pressure in the A clutch control circuit moves the A
clutch latch valve to the left which allows line pressure to hold the
mechanical A clutch applied.
