摘要：
A multi speed transmission comprising planetary gearsets (P1, P2, P3, P4), shafts and shift elements. The sun gear of gearset (P1) couples shaft (4) which can couple housing (G) via brake (04) and the carrier of set (P1) couples shaft (3) which can couple housing (G), via brake (03), and drive shaft (1) via clutch (13), and shaft (6) via clutch (36). Shaft (6) couples the ring gear of gearset (P2) and the sun gears of gearsets (P3, P4). Shaft (1) couples the sun gear of gearset (P2) and is operatively connected to the carrier of gearset (P3). Shaft (7) couples the ring gear of set (P1) and the carrier of gearset (P2). The ring gear of gearset (P4) couples shaft (5) which can couple housing (G) via brake (05) and output shaft (2) operatively couples the carrier of gearset (P4) and the ring gear of gearset (P3).
