Transmission Fluid Heat Exchanger
A transmission fluid heat exchanger is located on the bottom edge of the radiator. Transmission fluid inlet and outlet hose fittings are located on the driver's side of the transmission. The heat exchanger provides two functions:
- After initial start up, the transmission fluid is warmed up by the engine coolant as it passes through the heat exchanger. The heat exchanger is controlled by an integral thermostat which regulates the transmission fluid flow into the radiator exchanger. In this state the heat exchanger acts as a transmission oil heater.
- During operation at higher temperatures, the hot transmission fluid loses heat to the engine coolant when it passes through the heat exchanger and into the core of the radiator. See Fig 1 and Fig 2 .
