1999 Park Avenue with 9000 miles. Little old lady had it. It vibrates in seat, floor, etc. but not steering wheel at any speed over 55. New rotors, new tires that have been balanced twice, been aligned. GM mechanic at dealership is stumped. Anyone have a clue? Can the transmission cause a car to vibrate at 55 mph and above if there's a problem with it?
