Transmission fluid was leaking. Was told it was not covered under my warranty as the transmission cooler was damaged by stones. I asked for the part and detected that there were many stones embedded in he transmission cooler. This is a defect that Lincoln will not admit to. Potential hazard if you spring a leak while driving on the highway.
