Transaxle Cooling: Notes

WARNING: This page is about a different car, the 2012 Ford Edge. 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 (OTA) transmission fluid cooler
A non-repairable in-tank transmission fluid cooler
Front transmission fluid cooler tube assembly
Rear transmission fluid cooler tube assembly
Transmission mounted transmission fluid cooler outlet tube
Transmission mounted transmission fluid cooler inlet tube
Transmission fluid cooler bypass valve
Transmission fluid cooler - warmer

These vehicles are equipped with an OTA transmission fluid cooler and an in-tank transmission fluid cooler. The transmission fluid cooling system also consists of a transmission fluid cooler - warmer assembly which has a transmission cooler bypass valve mounted to the top of the transmission fluid cooler - warmer. Transmission fluid travels from the transaxle to the transmission fluid cooler - warmer. The transmission fluid cooler - warmer warms the transmission fluid to the transmission operating temperature using heated engine coolant. When the transmission fluid is at or above normal operating temperature, the transmission fluid cooler bypass valve opens allowing transmission fluid to travel from the transaxle through the in-tank transmission fluid cooler then through the OTA transmission fluid cooler then back to the transaxle. The transmission fluid cooler transfers heat from the transmission fluid to the outside air.
