Ford Ecosport: Transmission Cooling - 6-Speed Automatic Transmission – 6F35 / Description and Operation - Transmission Cooling - Overview
This
vehicle is equipped with an external transmission fluid cooler. The
transmission fluid cooler is an oil-to-air fluid cooler which is mounted
in front of the radiator. The cooling system also consists of a thermal
bypass valve which is mounted on the transmission. When the
transmission fluid is below normal operating temperature, transmission
fluid travels from the transmission to the thermal bypass valve and back
to the transmission. When the transmission fluid is at or above normal
operating temperature, the thermal bypass valve opens allowing
transmission fluid to travel from the transmission through the cooler
and back to the transmission. The transmission fluid cooler transfers
heat from the transmission fluid to the ambient air.
