While driving for a period of 30 minutes to a hour on cruise control then all of a sudden y cruise control sends up a error message n cuts out then my transmission drops from 7th gear to 6th gear and would get stuck and I cants shift it at all. I would have to pull over turn my of the car turn it back on just so the tranny would shift normal. Another 30 min or so it does it again n I have to repeat the process to reset my transmission.
