Transmission Cooler: Description and Operation
AUTOMATIC TRANSMISSION OIL COOLERTop View Of Transmission Oil Cooling Circuit:
Automatic Transmission Oil Cooler Lines:
The automatic transmission oil is cooled when it passes through a cooler in the radiator lower tank.
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.
TRANSMISSION AUXILIARY COOLER
Transmission Auxiliary Cooler:
Auxiliary transmission coolers are mounted ahead of the radiator. They operate in conjunction with the main cooler located in the radiator lower tank. The transmission oil is routed through the main cooler in the radiator lower tank first, then the auxiliary cooler before returning to the transmission.
