planetary gear set.
Due to the first direct control system in a
planetary automatic transmission
with nine
gears, it has also been possible to significantly increase hydraulic efficiency within the transmission.
Another goal was to implement the nine
gears with a minimal number of
planetary gear sets and shift elements.
A
