摘要：
A transmission having four planetary gearsets, and shafts and shift elements. Sun gear of 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 (78) to shaft (7), which couples sun gears of gearsets (P3, P4). Carrier of gearset (P1) couples the drive shaft, which couples ring gear of gearset (P2). Sun gear of gearset (P2) couples shaft (9), which is connectable via clutch (39) to shaft (3), which couples carrier of gearset (P3) and is connectable to housing (G) via brake (03). Carrier and ring gear of gearset (P4) couple, respectively output shaft and shaft (4), which is connectable to housing (G) via brake (04). The output shaft is connectable via clutch (26) to shaft (6), which couples ring gear of gearset (P1).
