1. Input shaft rotates clockwise.
S Forward clutch (C1) operates. (Connect input shaft to front sun gear)
2. Front sun gear rotates clockwise.
3. Planetary short pinion rotates itself counterclockwise.
4. Planetary long Pinion rotates itself clockwise.
5. Planetary carrier is going to rotate counterclockwise.

6. Ring gear rotates clockwise.
7. Counter drive gear rotates clockwise for ring gear and one.
8. Counter drive gear rotates counterclockwise
9. Differential gear drive pinion rotates counterclockwise for counter driven gear and one.
10. Differential gear rotates clockwise.
( Engine Brake)
1. Counter drive gear and Planetary ring gear rotates counterclockwise.
2. Planetary long pinion rotates itself counterclockwise.
3. Planetary short pinion rotates itself clockwise.
4. Planetary carrier revolves clockwise due to rotation itself counterclockwise of planetary long pinion, but driving
force loses due to free of 1 way clutch NO.2 (F2). Therefore Engine brake does not operate.

1. Input shaft rotates clockwise.
S Forward clutch (C1) operates. (Connect input shaft to front sun gear)
S Direct clutch (C2) operates. (Connect input shaft to planetary carrier)
2. Planetary short pinion and planetary long pinion can not rotate itself, and planetary gear unit rotates clockwise as
one.
3. Counter drive gear rotates clockwise for ring gear and one.
4. Counter drive gear rotates counterclockwise

5. Differential drive pinion rotates counterclockwise for counter driven gear and one.
6. Differential rotates clockwise.
( Engine Brake)
Driving force is connected to input shaft directory without 1 way clutch.
Therefore Engine Brake operates.
