Transmission Cooling - Overview

WARNING: This page is about a different car, the 2018 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.

The transmission fluid cooling system consists of the following:

Oil to air transmission fluid cooler
Transmission mounted transmission fluid cooler tube assembly
Transmission fluid thermal bypass valve
Transmission fluid cooler inlet tube
Transmission fluid cooler outlet tube

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 engine radiator. The cooling system also consists of a thermal bypass valve which is mounted on top of 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 outside air.
