Drive is transmitted from the torque converter (1) to the transmission input shaft (2) and via the 1st-3rd gear clutch (3) to the small sun gear (4).
The planet gear carrier (6) is held by the 1st gear one-way clutch (5).
NOTE:In selector lever position "1" the planet gear carrier is also held by the reverse gear brake (7) (engine braking).
The short planet gears (8) are driven by the small sun gear in the opposite direction of rotation to the output from the engine.
The short planet gears drive the long planet gears (9) in the same direction of rotation as the output from the engine.
The long planet gears drive the ring gear (10) in the same direction of rotation as the output from the engine.
The annulus is fixedly connected to the output wheel of the planetary gearset and drives the intermediate gear stage (11) in the opposite direction of rotation to the output from the engine.
The intermediate gear stage drives the differential assembly (12) in the same direction of rotation as the output from the engine.

Drive is transmitted from the torque converter (1) to the transmission input shaft (2) and via the 1st-3rd gear clutch (3) to the small sun gear (4).
The large sun gear (15) is held by the 2nd gear one-way clutch (14) and the 2nd-4th gear brake (13).
NOTE:In selector lever position "2" the large sun gear is also held by the 4th gear brake (16) (engine braking).
The short planet gears (8) are driven by the small sun gear in the opposite direction of rotation to the output from the engine.
The short planet gears drive the long planet gears (9) in the same direction of rotation as the output from the engine.
The long planet gears are supported by the large sun gear which is being held, and they drive the planet gear carrier (6) in the same direction of rotation as the output from the engine.
The long planet gears drive the ring gear (10) in the same direction of rotation as the output from the engine.
The annulus is fixedly connected to the output wheel of the planetary gearset and drives the intermediate gear stage (11) in the opposite direction of rotation to the output from the engine.
The intermediate gear stage drives the differential assembly (12) in the same direction of rotation as the output from the engine.

The drive is transmitted from the torque converter (1) on the one hand to the transmission input shaft (2) and via the 1st-3rd gear clutch (3) to the small sun gear (4), and on the other hand from the transmission input shaft via the 3rd/4th gear clutch (17) to the planet gear carrier (6).
As the drive is transmitted to two components simultaneously, there are no relative movements within the planetary gearset. The planetary gearset rotates as a complete unit.
NOTE:The 2nd-4th gear brake (13) remains engaged, but the large sun gear (15) can rotate in the same direction of rotation as the output from the engine by means of the 2nd gear one-way clutch (14), as a result of which the 2nd-4th gear brake has no influence on the transmission ratio.
The Annulus (10) is fixedly connected to the output wheel of the planetary gearset and drives the intermediate gear stage (11) in the opposite direction of rotation to the output from the engine.
The intermediate gear stage drives the differential assembly (12) in the same direction of rotation as the output from the engine.

Drive is transmitted from the torque converter (1) to the transmission input shaft (2) and via the 3rd/4th gear clutch (17) to the planet gear carrier (6).
The large sun gear (15) is held by the 4th gear brake (16), the 2nd gear one-way clutch (14) and the 2nd-4th gear brake (13).
NOTE:The short planet gears (8) and the small sun gear (4) co-rotate, but they have no influence on the transmission ratio.
The long planet gears (9) drive the annulus (10) in the same direction of rotation as the output from the engine.
The annulus is fixedly connected to the output wheel of the planetary gearset and drives the intermediate gear stage (11) in the opposite direction of rotation to the output from the engine.
The intermediate gear stage drives the differential assembly (12) in the same direction of rotation as the output from the engine.
