The multi-speed transmission has rotatable shafts, planetary gearsets (RS 1 , RS 2, RS 3, RS 4 ) and shifting elements (A, B, C, D, E). Carrier (ST 4 ) of gearset (RS 4 ) and the input shaft couple as shaft ( 1 ). Carriers (ST 2, ST 3 ) of respective gearsets (RS 2, RS 3 ) and the output shaft (AB) couple as shaft ( 2 ). Sun gears (SO 1, SO 4 ) of gearsets (RS 1, RS 4 ) couple as shaft ( 3 ). Carrier (ST 1 ) of gearset (RS 1 ) forms shaft ( 4 ). Sun gear (SO 3 ) forms shaft ( 5 ). Ring gears (HO 1, HO 3 ) of gearsets (RS 1, RS 3 ) couple as shaft ( 6 ). Sun and ring gears (SO 2, HO 4 ) respectively of gearsets (RS 2 , RS 4 ) couple as shaft ( 7 ). Carrier (ST 2 ) is shaft ( 8 ). In the flow of power, elements (A, B) are respectively between shafts ( 3, 4 ) and a transmission housing; element (C) is between shafts ( 1, 5 ); element (D) is between shafts ( 6, 8 ); and element (E) is between shafts ( 5, 7 ).
