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.

Inspection
Remove the starter motor.
Refer to: Starter Motor (303-06A Starting System - 3.0L EcoBoost, Removal and Installation).
Check the wear patterns on the starter motor drive gear
and the flywheel or flexplate ring gear. If the wear pattern is normal,
then install the starter motor...
