Ravigneaux gear set
The small ring gear is driven via the transmission input shaft. The long planetary gears drive the short planetary gears, which roll in the stalled large ring gear. An increased torque and reduced rpm occur as a result and this is transmitted to the dual planet carrier.

Single rear planetary gear system
The ring gear (9) rotates at the same speed due to the mechanical connection to the dual planet carrier. The planetary gears (51) roll over the stalled sun gear (11) and transmit the rotary motion to the planet carrier (10).

Single front planetary gear system
The ring gear (12) has a mechanical connection to the planet carrier (10) and rotates at the same speed. The planetary gears (52) roll on the stalled sun gear (14) and transfer the increased torque and reduced rotational speed to the transmission output shaft via the planet carrier (13). The transmission output shaft thus rotates with reduced transmission input speed in the direction of rotation of the engine.
