I need to get my tranny a tune up, and I have no experience on tranny work. I have brought it inot Aamco for a diagnosis, and I liked the guys doing the work, but the place is a little shady. Any experience with the following: I am in Northern NJ, Morris County Lee Myles Aamco Randolph Transmissions Passaic County Transmissions Advanced Transmissions Denville Transmission Morristown Transmission Service Any info/advice on what/who to look for in a transmission shop will be greatly appreciated. Thanks!
