Abstract: An arrangement for cooling oil in a gearbox of a vehicle which is powered by a combustion engine. An oil cooler is fitted in the vehicle close to the gearbox. An oil system circulates oil between the gearbox and the oil cooler. An oil circuit contains a circulating coolant to cool the oil in the oil cooler.
