rear and low planetary pinions respectively. With the
torque is transmitted through the torque converter as
rear planetary ring gear held stationary by the applied
described in a, above. The forward and first clutches are
first clutch, the rear carrier will rotate i n a clockwise
applied. The firs clutch application anchors the rear
direction. Since the rear carrier hub is splined to the low
planetary ring gear against rotation. The forward clutch
carrier ring gear, it will also rotate clockwise. Since two
application locks the turbine shaft and transmission main
members of the low planetary system are driving
shaft together so that they rotate as a unit. The rear sun
members (rotating at differing speeds), the third member
gear and low sun gear are splined to the main shaft and
(carrier) becomes the output member. This, in turn,
rotate with it and, in turn, they rotate the
drives the output shaft at a speed reduction of 1. 89: 1.
