My gf had her transmission flushed by a privately owned shop and they put dextron fluid in instead of SPIII. Her car never had problems before and began to have transmission problems 3 months later. We are battling with the owner now who admits he put in the wrong fluid, but said it wouldn't matter. We've had it taken apart by a national company (but which we now know he is friends with the local workers) who tell us that the metal bushings are going out and the problem has nothing to do with him putting in the wrong fluid. Please let me know your input on the situation. Thanks!
