Claim 0:
1. A method for managing an oil temperature of a transmission of a motor vehicle, the transmission comprising:
a lubrication circuit, and
an oil temperature management circuit comprising:
a liquid/liquid heat exchanger mounted on the lubrication circuit,
the lubrication circuit comprising:
a pump for circulating oil in the lubrication circuit,
a vehicle start detection module connected to a user device that is actuated just prior to vehicle cold start, and
a temperature sensor;

wherein the method comprises, before a starting stage of the motor vehicle, determining an imminence of the vehicle start, determining whether the temperature of the oil is lower than a first value, and activating the pump of the lubrication circuit so as to circulate the oil in the liquid/liquid heat exchanger if the temperature of the oil is lower than the first value.
