System Operation

Transmission Cooling

The transmission fluid cooling system consists of the following:

- Oil-To-Air (OTA) transmission fluid multi cooler

- Transmission fluid cooler tube assembly

- Transmission fluid thermal bypass valve

- Transmission fluid cooler inlet tube

- Transmission fluid cooler return tube

These vehicles are equipped with an external transmission fluid cooler. The transmission fluid cooler is part of the A/C condenser and cannot be serviced separately. The cooler is mounted in front of the engine radiator. The transmission fluid cooling system also consists of a transmission fluid thermal bypass valve which is mounted on the transmission main control cover. When the Motorcraft(R) MERCON(R) LV Automatic Transmission Fluid is below normal operating temperature, Motorcraft(R) MERCON(R) LV Automatic Transmission Fluid travels from the transmission to the transmission fluid thermal bypass valve then back to the transmission. When the Motorcraft(R) MERCON(R) LV Automatic Transmission Fluid is at or above normal operating temperature, the transmission fluid thermal bypass valve opens allowing Motorcraft(R) MERCON(R) LV Automatic Transmission Fluid to travel from the transmission through the transmission fluid cooler then back to the transmission. The transmission fluid cooler transfers heat from the Motorcraft(R) MERCON(R) LV Automatic Transmission Fluid to the outside air.
