A. Front Planetary Gear

B. Rear Planetary Gear

D - 1st Gear

1. The input shaft rotates clockwise.

The forward clutch (C1) operates. Connect the input shaft to the front sun gear.

2. The front sun gear rotates clockwise.
3. The planetary short pinion rotates itself counterclockwise.
4. The planetary long pinion rotates itself clockwise.
5. The planetary carrier is going to rotate counterclockwise.

The one-way clutch No. 2 (F2) operates. The lock revolves counterclockwise of the planetary carrier.

6. The ring gear rotates clockwise.
7. The counter drive gear rotates clockwise for ring gear and one.
8. The counter drive gear rotates counterclockwise.
9. The differential gear drive pinion rotates counterclockwise for the counter driven gear and one.
10. The differential gear rotates clockwise.

Engine Brake

1. The counter drive gear and planetary ring gear rotates counterclockwise.
2. The planetary long pinion rotates itself counterclockwise.
3. The planetary short pinion rotates itself clockwise.
4. The planetary carrier revolves clockwise due to rotation itself counterclockwise of the planetary long pinion, but driving force loses due to free of 1-way clutch No. 2 (F2). Therefore the engine brake does not operate.
