A power shift transmission has an input shaft, a first output shaft coaxial to the input shaft, a planetary transmission with a planet carrier, which is connected to the input shaft, and at least three shift elements. To minimize drag from open shift elements and to optimize shift times of a connectable synchromesh transmission, the planetary transmission has at least two stepped planetary sets, which may be mounted on a common planet carrier. Each stepped planetary set meshes on input and output sides with at least one sun gear. The first output shaft is connected to an output side sun associated with one stepped planetary set by a first shift element, the first output shaft is connected to an output side sun associated with another stepped planetary set by a second shift element, and input side sun gears are blocked relative to the transmission housing by a third shift element.
