METHOD OF MANAGING THE OIL TEMPERATURE OF A TRANSMISSION OF A MOTOR VEHICLE

The invention relates to a method of managing the oil temperature of a transmission of a motor vehicle, the transmission comprising a lubrication circuit (2) and an oil cooling circuit (3), the oil temperature management circuit comprising a liquid/liquid heat exchanger (30) mounted on the lubrication circuit (2), the lubrication circuit (2) comprises a pump (21) for circulating the oil in the lubrication circuit and a temperature sensor (23) characterized in that, before a starting stage of the vehicle, if the temperature of the oil is lower than a first value, the pump (21) of the lubrication circuit is activated so as to circulate the oil in the liquid/liquid exchanger (30).
