1st Gear (D Selected)
The gear selector lever and the manual selector valve spool are in the 'D' position. Engine torque is transmitted from
the torque converter to the planet gearset 3. The torque is applied to the input shaft gear via the application of clutch
'A'. The freewheel clutch locks the planet carrier of gearset 2 in the direction of rotation.
The larger diameter input shaft gear drives the planet gears of gearset 3, which rotate inside the locked ring gear 3.
This rotation is passed via the planet carrier of gearset 3 to the output shaft.
In 1st gear with braking effect when coasting, the brake clutch 'F' is also applied locking the ring gear 3 in both
directions.
