A transmission heat exchange system comprises a transmission heat exchanger 103, a first valve 106 and a second valve 107 each having at least a first coolant input in which is a temperature responsive component that controls the valves 106, 107 from open to closed states. A pump 104 pumps coolant from the heat exchanger 103 to the first valve 106 and second valve 107. The valves 106, 107 in the closed state allow a bleed rate of coolant to flow from the heat exchanger 103 and in the open state they allow coolant to flow at flow rates which are greater than the bleed rate. The temperature responsive components are partially immersed within the coolant in the first coolant inputs and may comprise a material, e.g. wax, which changes volume with the temperature of coolant within the first coolant inputs. The heat exchange system may be in a vehicle and may be part of an engine heat exchange system 101 comprising a radiator 109, an engine thermostat 122 and a cabin heater 121. |
