How often has the transmission been changed prior to the failure? I have a 2007 Expedition and recommended fluid changes are at 20k miles.
I purchased it new and at 75,000 miles - I had the Ford dealer changed the fluid and filter (not a flush). The vehicle is used for passenger use (no towing) and often driven at moderate speeds for some distance (vs. stop-and-go driving). The owner’s manual states the change interval is 150,000 miles.
