Operating Principles Of Each Range

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

1. 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.
2. Parking pawl that is linked with select lever parking Gear meshes with and fastens output shaft mechanically.

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

Input shaft→Front internal Gear→Front carrier→Rear internal Gear→Rear carrier→Middle internal Gear→Middle carrier→Output shaft

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

1. Fastens the front brake.
2. The 3rd one-way clutch regulates reverse rotation of the front sun Gear.

3. 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

1. The front brake is released and sun Gear turns freely forward.
2. The input clutch is coupled and the front and middle internal Gears are connected.

3. 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.

* POWER FLOW 

Input shaft→Front internal Gear→Front carrier→Rear internal Gear→Rear carrier→Middle internal carrier→Middle carrier→Output shaft

1. The front brake fastens the front sun Gear.
2. The direct clutch is released and the rear carrier and rear sun Gear are disconnected.
