Abstract

An arrangement for warming the oil in a gearbox in a vehicle powered by a combustion engine. A first pipe system with a first flow device which makes possible circulation of oil from the combustion engine through a heat exchanger. A second pipe system with a second flow device makes possible circulation of oil from the gearbox through the heat exchanger. A control device controls the flow devices so that flow of oil through the heat exchanger is obtained in situations in which the oil in the gearbox is at a too low temperature with respect to a desired temperature. The motor oil in the combustion engine can thus be used for heating the oil in the gearbox during cold starts of the combustion engine.
