The 8-gear transmission comprises an input shaft (AN), an output shaft (AB), four planetary gearsets (RS 1 , RS 2 , RS 3 , RS 4 ), eight rotary shafts ( 1, 2, 3, 4, 5, 6, 7, 8 ), and five shifting elements (A, B, C, D, E). A carrier (ST 4 ) of the fourth gearset (RS 4 ) and the input shaft (AN) are connected to each other as the first shaft ( 1 ). A ring gear (HO 2 ) of the second gearset (RS 2 ) and a carrier (ST 3 ) of the third gearset (RS 3 ), and the output shaft (AB) are connected as a second shaft ( 2 ). A sun gear (SO 1 ) of the first gearset (RS 1 ) and a sun gear (SO 4 ) of the fourth gearset (RS 4 ) are connected as the third shaft ( 3 ). A ring gear (HO 1 ) of the first gearset (RS 1 ) forms the fourth shaft ( 4 ). A sun gear (SO 3 ) of the third gearset (RS 3 ) forms the fifth shaft ( 5 ). A carrier (ST 1 ) of the first gearset (RS 1 ) and a ring gear (HO 3 ) of the third gearset (RS 3 ) are connected to each other as the sixth shaft ( 6 ). A sun gear (SO 2 ) of the second gearset (RS 2 ) and a ring gear (HO 4 ) of the fourth gearset (RS 4 ) are connected to each other as the seventh shaft ( 7 ). A carrier (ST 2 ) of the second gearset (RS 2 ) forms the eighth shaft ( 8 ). The first shifting element (A) is arranged within the power flow between the third shaft ( 3 ) and a housing (GG) of the transmission, the second shifting element (B) is arranged within the power flow between the fourth shaft ( 4 ) and the housing (GG), the third shifting element (C) is arranged within the power flow between the first and fifth shaft ( 1, 5 ), the fourth shifting element (D) is arranged within the power flow between the fifth and eighth shaft ( 5, 8 ), and the fifth shifting element (E) is arranged within the power flow between the fifth and the seventh shaft ( 5, 7 ).
