Edge AWD V6-3.5L (2009)
Transmission Cooler: Description and Operation
Transaxle Cooling
The transmission fluid cooling system consists of the following:
-
Oil-To-Air (OTA) transmission fluid cooler
-
Transmission fluid cooler tube assembly
-
Transmission fluid cooler thermal bypass valve (part of the transmission fluid cooler tube assembly)
-
Transmission fluid cooler outlet tube
-
Transmission fluid cooler return tube
This vehicle is equipped with an external transmission fluid cooler. The transmission fluid cooler is mounted in front of the engine radiator. The
transmission fluid cooling system also consists of a transmission fluid cooler thermal bypass valve which is mounted on the transaxle main control cover.
When the transmission fluid is below normal operating temperature, transmission fluid travels from the transaxle to the transmission fluid cooler thermal
bypass valve then back to the transaxle. When the transmission fluid is at or above normal operating temperature, the transmission fluid cooler thermal
bypass valve opens, allowing transmission fluid to travel from the transaxle through the transmission fluid cooler then back to the transaxle. The
transmission fluid cooler transfers heat from the transmission fluid to the outside air.
