transmission section output to the output drive
assembly by the output drive sun gear shaft.
The integral sun gear imparts torque to the
planetary pinions which are mounted in a sta-
tionary carrier. In turn, the pinions transmit
torque to the ring gear. The ring gear, splined
to the output shaft, transmits torque to the
output shaft.
