Title: Multistage transmission

Abstract: A transmission having basic and reversing transmissions. The basic transmission has planetary gearsets, shafts and shift elements. A sun of gearset (P1) couples the drive shaft, which can couple shaft (6) and the suns of gearsets (P2, P3), and shaft (5) and the carrier and ring of gearsets (P2, P3) respectively. Carrier of gearset (P1) couples shaft (4), which couples the ring of gearset (P2). The ring of gearset (P1) couples shaft (3). Shafts (3, 4, 5) can couple the housing. The output shaft couples the carrier of gearset (P3). The reversing transmission has a minus planetary gearset with a sun which couples and is driven by the basic transmission output, and a carrier that can couple the housing via a locking element, and a ring that couples the reversing transmission output which can couple, via another locking element, the basic transmission output.
