We started having transmission problems at 20,000 miles. It would shift hard at around 40 MPH.We took it in (not at purchasing dealership)about ten times before they finally changed the transmission. I argued with the transmission mechanic that it was not right.They tried something different each time it was brought in. They adjusted the linkage, changed the spark plugs, changed the radiator, new torque converter, etc before changing the transmission. By this time the warranty was off and they wanted me to pay for it. After lots of arguing the dealer helped cover the cost above what Ford payed.There was 30,000 miles on the vehicle by the time this was done. Been running good ever since.
