Ford recommends that the transmission fluid and filter be changed at 150,000 miles. They do NOT recommend fluid exchanges or flushes, because they can take debris from the pan and filter and pull it through the rest of the transmission, causing damage.
Agree, except 150,000 is way to long before changing oil and changing filter.
Transmission oil should be changed at 30,000 miles and the oil and filter at 60,000 miles at least according to FordTechMakuloco on YouTube which I agree with.
