The present invention concerns a method of thermal management of a transmission of an axle (4) of an electrical vehicle and a circuit used for the method. The circuit comprises a coolant pump (1), one or more on-board units, a three way valve (5) and the axle (4), which axle (4) comprises a transmission. Coolant of a cooling system of the vehicle is made to pass the on-board units to pick up heat losses. The on-board units may be power electronics (2), an electrical machine (3), a battery and/or an on-board charger.
