The invention concerns a gearbox comprising an input shaft (8) and an output shaft (20); a first epicyclic gear (10) that is connected to the input shaft (8); a second epicyclic gear (12) that is connected to the first epicyclic gear (10); a first electrical machine (14) that is connected to the first epicyclic gear (10); a second electrical machine (16) that is connected to the second epicyclic gear (12); a first gear pair (60) that is arranged between the first epicyclic gear (10) and the output shaft (20); and a second gear pair (66) that is arranged between the second epicyclic gear (12) and the output shaft (20). A side shaft (18) is arranged between the relevant first and second epicyclic gear (10, 12) and the output shaft (20); that the side shaft (18) is connected to the output shaft (20) through a final gear (21); and that the final gear (21) comprises a gear element (92), that is arranged at the side shaft (18) in a manner that allows it to be disengaged. The invention concerns also a vehicle (1) that comprises such a gearbox (2), and a method to control such a gearbox (2). The invention concerns also a computer program (P) to control a gearbox, and a computer program product comprising program code for an electronic control unit (48) or another computer (53) in order to implement the method according to the invention.
