In a cooling circuit of a liquid-cooled internal combustion engine of a motor vehicle having a coolant pump, an electrical mixing valve, a radiator, a heater, an engine-oil heat exchanger, a transmission-oil cooler with a heat flux from the transmission oil to the ambient air, a transmission-oil heat exchanger providing for a heat flux between the transmission oil and the cooling water and being arranged in parallel flow circuit with the transmission-oil cooler, and an actuator for controlling the oil flow distribution, an electrical mixing valve is arranged between the transmission-oil cooler and the transmission-oil heat exchanger, such that the heat transfer in the transmission-oil heat exchanger can be controlled by the electrical mixing valve by controlling the coolant flow through the transmission oil heat exchanger and the radiator.
