Abstract: A gearbox for an electric powertrain, said gearbox comprising a primary shaft, on which are arranged a first primary gear which is fixed in rotation with respect to the primary shaft, a second primary gear and a third primary gear and a secondary shaft, on which are arranged a first secondary gear that is meshing with the first primary gear and that is by default free to rotate around the secondary shaft, a second secondary gear meshing with the second primary gear and a third secondary gear meshing with the third primary gear. The gearbox further includes a first coupling member, which is arranged along the secondary shaft and which can be moved between an engaged position, in which it couples the first secondary gear in rotation with the secondary shaft and a neutral position.
