I had a friend preformed a diagnostic on my car for free but does not specialize in American care come up with a shift Soleniod problem and called ford to confirm the codes. They gave him a price on the part. I took it to a dealer and they came up with a finale code which is on of the codes that I got from my friend and said I need a new tranny. Who do I believe? Friend came up with;p0745: Cntrl Sol. A circuit malfunctionp0733: Gear 3 ratio Incorrectp0799: Cntrl Sol. C.
