Transaxle Cooling: Notes

The transmission fluid cooling system consists of the following:

• OTA transmission fluid combo cooler
• Transmission fluid cooler tube assembly
• Transmission fluid cooler thermal bypass valve
• Transmission fluid cooler outlet tube
• Transmission fluid cooler inlet tube

This vehicle is equipped with an external transmission fluid cooler. The transmission fluid cooler is part of the A/C condenser and cannot be serviced separately. The transmission fluid cooler is mounted in front of the engine radiator. The cooling system also consists of a transmission fluid cooler thermal bypass valve which is mounted on the transmission's main control cover. When the transmission fluid is below normal operating temperature, transmission fluid travels from the transmission to the transmission's fluid cooler thermal bypass valve and then back to the transmission. 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 transmission through the transmission's fluid cooler and then back to the transmission. The transmission fluid cooler transfers heat from the transmission fluid to the outside air.
