•Forward clutch
• Forward one-way
clutch
• Brake band 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 planetary carrier compared with
that of the 1st speed.

•
High clutch
• Forward clutch
• Forward one-way
clutch Input power is transmitted to front planetary carrier through high clutch. And front planetary carrier is con-
nected 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.

•High clutch
• Brake band
• 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
4 position, there is no one-way clutch in the power transaxle line and engine brake
can be obtained when decelerating.

Reverse clutch
• Low & 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 transaxle line, engine brake can be obtained
when decelerating.
