E Clutch Hydraulic Circuits

E Clutch Hydraulic Operation 5th-6th Shift

Line pressure is supplied to the E clutch control valve. LPC pressure is supplied to the gain control valve. LPC pressure positions the gain control valve to the right end of the valve bore. As SSE turns on, it moves the E clutch control valve allowing regulated line pressure to flow to the mechanical E clutch.

E Clutch Hydraulic Operation 2nd-3rd, 4th-5th, and 9th-10th Shifts

Line pressure is supplied to the E clutch control valve. LPC pressure is supplied to the gain control valve. The LPC pressure is low and the gain control valve stays in the default position at the left end of the valve bore. As SSE turns on, it moves the D clutch control valve allowing regulated line pressure to flow to the mechanical E clutch.
