Transmission Cooler: Description and Operation

Transmission Oil Cooler 
The transmission oil cooler is a heat exchanger. It is located inside the right side end tank of the radiator. The transmission fluid temperature is regulated
by the temperature of the engine coolant in the radiator.

The transmission oil pump, pumps the fluid through the transmission oil cooler line to the transmission oil cooler. The fluid then flows through the cooler
where the engine coolant absorbs heat from the fluid. The fluid is then pumped through the;transmission oil cooler return line, to the transmission.
