I'm rating AAMCO highly based on personality. I've only used them once, but if you know anything about transmissions, which most of us don't (and most car people don't for that matter), you know you're really in a black box. What I mean is that if they say, you want to come by and we can show you what's going on? It would be like going to NASA to look at one of their engines laid out in pieces, you wouldn't know what you're looking at. So it breaks down to their personality; I found both Mike and his partner to be nice guys, they fixed whatever was going on with the transmission, they were personable, and the car has been reacting pretty well. It took about a week for the car to be fixed, and I didn't compare pricing, it seemed a bit high but I have no way to judge it. Overall 5 stays for the guys at AAMCO.
