A gearbox (1, 1a..1d) for an electric drivetrain (28, 28a..28e) is proposed, which comprises a gearbox input (2), a gearbox output (4), a number of gear wheels (5..8) and at least a first and a second form-fit clutch (9, 10) providing at least two switchable transmission ratios between the gearbox input (2) and the gearbox output (4) in different switching states (D1, D2) of the form-fit clutches (9, 10). In addition, a parking state (P) is provided, in which both the first transmission ratio and the second transmission ratio are engaged/activated between the gearbox input (2) and the gearbox output (4) at the same time and a transmission of a rotational movement between the gearbox input (2) and the gearbox output (4) is blocked. Moreover, an electric drivetrain (28, 28a..28e) with such a gearbox (1, 1a..1d) and a vehicle (34) with such an electric drivetrain (28, 28a..28e) are disclosed.
