The transmission has four planetary gear sets and shafts and shift elements. Sun gear of the planetary gearset (P1) couples shaft (5) which couples ring gear of gearset (P3) and is connectable, via clutch (58), to shaft (8), which couples carrier of gearset (P2) and is connectable, via clutch (89), to shaft (9), which couples sun gears of gearsets (P3, P4). Carrier of gearset (P1) couples drive shaft (1), which is connectable, via clutch (16), to shaft (6), which couples ring gear of gearset (P2). Sun gear of gearset (P2) couples shaft (3), which couples carrier of gearset (P3) and is connectable to the housing via brake (03). Ring gear of gearset (P4) couples shaft (4) which is connectable to the housing via brake (04). Output shaft (2) couples carrier of gearset (P4) and is connectable, via clutch (27), to shaft (7) which couples ring gear of gearset (P1).
