522 D drive range second gear

In D range in second gear, both direct and forward clutches are engaged. At the same time the second gear band brake holds the double sun gear and reverse pinion carrier stationary.

Engine torque is transmitted through the locked overdrive gear set similarly to first gear. It is then conveyed through the applied forward clutch via intermediate shaft to the forward annular gear. With the double sun gear held by the applied second gear band brake, the clockwise rotation of the forward annular gear compels the pinion gears to rotate on their own axes and roll 'walk' around the stationary sun gear in a clockwise direction. Because the forward pinion gear pins are mounted on the pinion carrier, which is itself attached to the output shaft, the output shaft will be driven clockwise at a reduced speed ratio of approximately 1.46.
