Driven gear of reduction gearset
1st and 2nd planetary gearset:
The drive is transmitted from the transmission input shaft (1) to the sun gear (2nd set) (2).
The ring gear (2nd set) (3) is held by the 1st - 3rd gear clutch (4) and the 1st gear one-way clutch (5).
NOTE:In Select-Shift-Mode the ring gear (2nd set) is also held by the reverse gear brake (6) via the 1st - 3rd gear clutch (engine braking).
The planetary gears roll on the ring gear (2nd set) which is being held, thereby driving the planetary gear carrier (2nd set) and the ring gear (1st set) (7).
The planetary gear carrier (2nd set) is rigidly linked to the driven gear of the 1st and 2nd planetary gearset (8).
The 1st planetary gearset has no influence on the transmission.
Reduction planetary gearset:
The driven gear of the 1st and 2nd planetary gearset drives the drive gear for the reduction gearset (9), which is rigidly linked to the ring gear (10).
The sun gear (11) is held by the one-way clutch (12).
NOTE:In Select-Shift-Mode the sun gear is held by the reduction brake band (13) (engine braking).
The planetary gears roll on the sun gear, which is being held, and drive the planetary gear carrier (14), which is rigidly linked to the driven gear of the reduction gearset (15).
The driven gear of the reduction gearset drives the differential (16).

Planetary gear carrier (1st set)
1st and 2nd planetary gearset:
The drive is transmitted from the transmission input shaft (1) to the sun gear (2nd set) (2).
The ring gear (2nd set) (3) is initially held by the 1st - 3rd gear clutch (4) and the 1st gear one-way clutch (5).
As a result, the planetary gears roll on the ring gear (2nd set) which is being held, thereby driving the planetary gear carrier (2nd set) and the ring gear (1st set) (7).
The planetary gears (1st set) roll on the sun gear (1st set) (18) which is being held by the 2nd/4th/5th gear brake (17).
As a result, they drive the planetary gear carrier (1st set) (19), and therefore also the ring gear (2nd set) via the 1st - 3rd gear clutch.
The resulting relative movement is transmitted via the planetary gear carrier (2nd set) to the driven gear of the 1st and 2nd planetary gearset (8).

Planetary gear carrier (1st set)
1st and 2nd planetary gearset:
Drive is transmitted from the transmission input shaft (1) to the sun gear (2nd set) (2) and via the 3rd - 5th gear clutch (20) to the planetary gear carrier (1st set) (19). The planetary gear carrier (1st set) drives the ring gear (2nd set) (3) via the 1st - 3rd gear clutch (4).
As two components are being driven simultaneously in the 2nd planetary gearset, there is no resulting relative movement. The planetary gearsets rotate as complete units.
The planetary gear carrier (2nd set) and the ring gear (1st set) (7) are rigidly linked to the driven gear of the 1st and 2nd planetary gearset (8).
Reduction planetary gearset:
The driven gear of the 1st and 2nd planetary gearset drives the drive gear for the reduction gearset (9), which is rigidly linked to the ring gear (10).
The sun gear (11) is held by the reduction brake band (13) (engine braking).
The planetary gears roll on the sun gear, which is being held, and drive the planetary gear carrier (14), which is rigidly linked to the driven gear of the reduction gearset (15).
The driven gear of the reduction gearset drives the differential (16).

1st and 2nd planetary gearset:
Drive is transmitted from the transmission input shaft (1) via the 3rd - 5th gear clutch (20) to the planetary gear carrier (1st set) (19).
The planetary gears (1st set) roll on the sun gear (1st set) (18) which is being held by the 2nd/4th/5th gear brake (17).
As a result, the planetary gear carrier (2nd set) and the ring gear (1st set) (7) are driven.
This is rigidly linked to the driven gear of the 1st and 2nd planetary gearset (8).
The 2nd planetary gearset has no influence on the transmission.
