ABSTRACT:
A planetary gear train for an automatic transmission comprises a basic planetary gearing, an output planetary gear set, and a change speed arrangement including clutches and brakes. One of a sun gear and a ring gear of the output planetary gear is constantly connected to an output member of the basic planetary gearing and the other is connectable via a clutch to a rotary element of the basic planetary gearing which is held stationary during operation with the first gear ratio or reverse. A pinion carrier of the output planetary gear set is constantly connected to an output shaft of the transmission.
