The transmission with nine forward and one reverse gear includes four planetary gearsets, eight shafts and six shifting elements, the sun gear of gearset (P1) couples shaft (4) which can couple brake (04) to the housing. The input shaft can couple, via clutch (13), shaft (03) which is couples the carrier of gearset (P1) and the ring gear of gearset (P4) and can couple, via brake (03), the housing. The input shaft can couple, via clutch (16), shaft (6) which couples the ring gears of gearsets (P2, P3) and can couple, via clutch (17), shaft (7) which couples the sun gear of gearset (P2) and the ring gear of gearset (P1). Shaft (8) couples the carriers of gearsets (P2, P4). Shaft (5) couples the sun gears of gearsets (P3, P4) and can couple, via brake (05), the housing. The output shaft couples the carrier of gearset (P3).
