60mph is about 1700 RPM's in 4th gear (O/D) for my truck. That is about as high as it should be since I have the highest rear end gear ratio Ford offers stock with the Expedition, 3.73's. Any lower gear ratio and you will run lower RPM's at the same speed.
Are you experiencing high RPM's? If so is your O/D off light flashing on the shifting stalk?
