Description and Operation - E Clutch

Overview

Ring gear No. 3 is mechanically connected to sun gear No. 4, and both are connected to the E clutch. When the E clutch is applied, torque from the input shaft is transmitted to ring gear No. 3 and sun gear No. 4.

E Clutch Hydraulic Apply 5-6 Shift

Line pressure is supplied to the E clutch control valve. LPC pressure is supplied to the boost control valve. LPC pressure positions the boost control valve at the right end of the valve bore. When SSE is energized, it moves the E clutch regulator valve, allowing regulated line pressure to flow to the E mechanical clutch.

E Clutch Hydraulic Apply 2-3, 4-5 and 9-10 Shifts

Line pressure is supplied to the E clutch control valve. LPC pressure is supplied to the boost control valve. LPC pressure is low, and the boost control valve remains in its default position at the left end of the valve bore. When SSE is energized, it moves the D clutch control valve, allowing regulated line pressure to flow to the E mechanical clutch.
