Lincoln Aviator: Transmission Cooling - 10-Speed Automatic Transmission – 10R80 MHT / Description and Operation - Transmission Cooling - Overview

Transmission Cooling

The transmission fluid cooling system consists of a heat exchanger mounted to the transmission. Transmission fluid cooler tubes connect the transmission to the heat exchanger. The heat exchanger has both transmission fluid and engine coolant flowing through it in separate chambers. When the transmission fluid is cooler than the engine coolant, the heat exchanger warms the transmission fluid. When the transmission fluid is warmer than the engine coolant, the heat exchanger cools the transmission fluid. A coolant control valve controls coolant flow to the transmission fluid cooler.
