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.

WARNING:
Before working on or disconnecting any of the fuel tubes or fuel
system components, relieve the fuel system pressure to prevent
accidental spraying of fuel. Fuel in the fuel system remains under high
pressure, even when the engine is not running...
