NHTSA complaint #11754150

Owner complaint summary

While driving truck down highway with cruise set at 68mph . I was in a bit of incline( not towing) vehicle violently downshifted from 10th to 1st . Service powertrain wrench came up on dash . Vehicle was derated . I came to a stop and shut down key off restarted . Vehicle operated normally again. Took vehicle to ford dealership where they could not find any issue . They also installed a pcm update at that time. Since then the vehicle has a harsh 3-4,5,6 shift and flaring in 7,8,9&10. I am convinced and concerned that the transmission is hurt due to what happened. Ford quoted 13,000.00 to install a new transmission. The truck has never been abused. I don’t wish what is happening to me on anyone as a inexperienced driver in winter conditions would have caused a major accident.
