Rear sun gear drives rear planetary carrier and combined front internal gear. Front internal
gear now rotates around front sun gear accompanying front planetary carrier.
As front planetary carrier transfers the power to rear internal gear through forward clutch and
forward one-way clutch, this rotation of rear internal gear increases the speed of rear plane-
tary carrier compared with that of the 1st speed.
