“M1” position 1st gear
1.
Input shaft rotates clockwise.
2.
Forward clutch operates. (Connect input shaft to main rear internal gear.)
3.
Main rear internal gear rotates clockwise.
4.
Main rear planetary pinion gear rotates itself clockwise.
5.
Main front large planetary pinion gear rotates itself clockwise for rear planetary pinion gear and one.
6.
Main front small planetary pinion gear rotates itself counterclockwise.
7.
Main front internal gear is going to rotates counterclockwise.
8.
1st and reverse brake operates. (Lock rotation of main front internal gear.)
9.
Main planetary carrier revolves clockwise due to reaction force of front small planetary pinion gear.
10. Counter drive gear rotates clockwise for main planetary carrier and one.
11. Counter driven gear rotates counterclockwise.
12. U/D front internal gear rotates counterclockwise for counter driven gear and one.
13. U/D front planetary pinion gear rotates itself counterclockwise.
14. U/D sun gear rotates clockwise.
15. U/D rear planetary pinion gear rotates itself counterclockwise.
16. B5 brake operate. (Lock rotation of U/D rear planetary carrier.)
17. U/D rear internal gear rotates counterclockwise.
18. U/D front planetary carrier and output shaft rotates counterclockwise for U/D rear internal gear and one.
19. Final gear clockwise.
●
During deceleration, driving force is connected to input shaft directly without one-way clutch. Therefore,
engine brake operates.
