Wierd problem with my Grand Prix 2000 SE 3.1. After a highway cruise (not short city drives), my transmission starts to shift very rough and revs louder. If I shut the engine off and restart, its okay for a while. Ive had it checked out by dealer - all that ended up happening was they changed fluid and filter for a lot of money - ie. they are stumped or lazy. It still does the same thing. Would a tranny shop be a better choice ? Any advice is really appreciated.
