Transmission Cooler: Description and Operation
LOCATION
The automatic transmission oil is cooled when it passes through a cooler in the radiator lower tank.
LEAKS
In case of a leak in the transmission oil cooler, engine coolant may become mixed with transmission fluid. Transmission fluid may also have
entered the engine cooling system. Both cooling system and transmission should be drained and inspected in the event cooler is leaking.
AUXILIARY COOLER
Oil-to-air (auxiliary) transmission coolers are mounted ahead of radiator. They operate in conjunction with main cooler located in radiator side
tank. The transmission oil is routed through main cooler in radiator side tank first. It is then routed through auxiliary cooler before returning to
transmission.
