“D”, “M2” positions 2nd 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 and one.
6.
2nd brake and 2nd coast brake operates.
7.
One-way clutch No. 1 operates. (Lock rotation of main sun gear.)
8.
Main planetary carrier revolves clockwise due to reaction force of front large planetary pinion gear.
9.
Counter drive gear rotates clockwise for main planetary carrier and one.
10. Counter driven gear rotates counterclockwise.
11. U/D front internal gear rotates counterclockwise for counter driven gear and one.
12. U/D front planetary pinion gear rotates itself counterclockwise.
13. U/D sun gear rotates clockwise.
14. U/D rear planetary pinion gear rotates itself counterclockwise.
15. B5 brake operate. (Lock rotation of U/D rear planetary carrier.)
16. U/D rear internal gear rotates counterclockwise.
17. U/D front planetary carrier and output shaft rotates counterclockwise for U/D rear internal gear and one.
18. Final gear clockwise.
●
During deceleration, driving force is connected to input shaft directly without one-way clutch. Therefore,
engine brake operates.
