Forward one-way clutch
Input power is transmitted to front planetary carrier through high clutch. And front plan-
etary carrier is connected to rear internal gear by operation of forward clutch and forward
one-way clutch.
This rear internal gear rotation and another input (the rear sun gear) accompany rear
planetary carrier to turn at the same speed.

Forward clutch (Does not affect
power transmission)
Input power is transmitted to front carrier through high clutch.
This front carrier turns around the sun gear which is fixed by brake band and makes front
internal gear (output) turn faster.
Engine brake
At D

Low and reverse brake
Front planetary carrier is stationary because of the operation of low and reverse brake.
Input power is transmitted to front sun gear through reverse clutch, which drives front
internal gear in the opposite direction.
Engine brake
As there is no one-way clutch in the power transmission line, engine brake can be
obtained when decelerating.
