Operating Principles of Each Range
OPERATING PRINCIPLES OF EACH RANGE1. N range
Since the forward and reverse brakes are released, driving force of input shaft is not transmitted to output shaft.
2. P range
^ 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.
^ Since the middle sun gear rotates forward during deceleration, the forward one-way clutch runs idle and engine brake is not activated.
3. D, M2, M3, M4, M5 range 1st speed
^ 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.
POWER FLOW
Input shaft =>Front internal gear =>Front carrier =>Rear internal gear =>Rear carrier =>Middle internal gear =>Middle carrier =>Output shaft
4. D, M3, M4, M5 range ratio 2nd
^ Fasten the front brake.
^ The front brake and the forward one-way clutch regulate reverse rotation of the mid sun gear.
The direct clutch is coupled and the rear carrier and the rear sun gear 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 3rd one-way clutch regulates reverse rotation of the front sun gear.
5. D, M3, M4, M5 range 3rd speed
^ Fastens the front brake.
^ 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 3rd one-way clutch regulates reverse rotation of the front sun gear.
6. D, M4, M5 range 4th speed
^ 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.
POWER FLOW
Input shaft =>Front internal gear =>Front carrier =>Rear internal gear =>Rear carrier =>Middle internal carrier =>Middle carrier =>Output shaft
7. D, M5 range 5th speed
^ The front brake fastens the front sun gear.
POWER FLOW
Input shaft =>Front internal =>Front carrier =>Rear internal input shaft =>Middle internal =>Rear carrier =>Rear sun gear =>Middle sun carrier =>Middle carrier =>Output shaft
^ The direct clutch is released and the rear carrier and rear sun gear are disconnected.
8. R range
^ 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.
POWER FLOW
Input shaft =>Front internal =>Front carrier =>Rear internal =>Rear sun gear =>Middle sun gear =>Middle carrier =>Output shaft
