Transmission cooler and oil cooler -- also overheating in general

George...

Here is how the shop manual describes the oil coolers:
"Engine Oil Cooler
The engine oil cooler is a heat exchanger. It is located inside the left side end tank of the radiator. The engine oil temperature is controlled by the temperature of the engine coolant that surrounds the oil cooler in the radiator.

The engine oil pump, pumps the oil through the engine oil cooler line to the oil cooler. The oil then flows through the cooler where the engine coolant absorbs heat from the oil. The oil is then pumped through the oil cooler return line, to the oil filter, to the engine block oil system."

You would have to remove the end tank to see the actual cooler. It sort of resembles a bellows with coolant on the outside and oil flowing through the inside.

Hope this helps.
