Operating Principles Of Each Range

Since the forward and reverse brakes are released, driving force of input shaft is not transmitted to output shaft.

• Since the forward and reverse brakes are released, as those in the N range, driving force of input shaft is not transmitted to output shaft.
• Parking pawl that is linked with select lever parking gear meshes with and fastens output shaft mechanically.

• Fastens the front brake.
• The front brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
• The 1st one-way clutch regulates reverse rotation of the rear sun gear.
• The 3rd one-way clutch regulates reverse rotation of the front sun gear.

• Since the middle sun gear rotates forward during deceleration, the forward one-way clutch runs idle and engine brake is not activated.

* POWER FLOW 

Input shaft ==> Front internal gear ==> Front carrier ==> Rear internal gear ==> Rear carrier ==> Middle internal gear ==> Middle carrier ==> Output shaft

• Fasten the front brake.
• The front brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
• The 3rd one-way clutch regulates reverse rotation of the front sun gear.

The direct clutch is coupled and the rear carrier and the rear sun gear are connected.

• Fastens the front brake.
• The 3rd one-way clutch regulates reverse rotation of the front sun gear.

• The high & low reverse clutch is coupled and the middle and rear sun gears are connected.

* POWER FLOW 

Input shaft ==> Front internal gear ==> Front carrier ==> Rear internal gear ==> Rear carrier ==> Rear carrier ==> Middle internal gear ==> Middle carrier ==> Output shaft

• The front brake is released and sun gear turns freely forward.
• The input clutch is coupled and the front and middle internal gears are connected.

• Driving force is conveyed to the front internal gear, the middle internal gear, and the rear carrier and the three planetary gears rotate forward as a unit.

Input shaft ==> Front internal gear ==> Front carrier ==> Rear internal gear ==> Rear carrier ==> Middle internal carrier ==> Middle carrier ==> Output shaft

• The front brake fastens the front sun gear.
• The direct clutch is released and the rear carrier and rear sun gear are disconnected.

• The front brake fastens the front sun gear.
• The high & low reverse clutch is coupled and the middle and rear sun gears are connected.
• The reverse brake fastens the rear carrier.
