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.
