Trans cooler

This is an external trans cooler and same principle is applied with a trans cooler thats integrated into the radiator. On our light cars a external trans cooler isnt needed, a integrated cooler will effectively keep up with cooling demands for the trans in these cars.

As op mentioned it came out of a newport, a big heavy car. An external trans cooler was more than likely used because of the cooling demands of the engine. A heavier vehicle requires a greater cooling capability for the engine. Instead of using a integrated trans cooler in the rad the used a external cooler to allow the rad to put all its cooling capability toward cooling the engine.


If they were for warming the fluid then they wouldnt be installed in the south, just as block heaters arent common in the south and popular in the north due to the use. If trans cooler was for warming the fluid than they wouldnt be installed in vehicles in the south and only the north.
