I need some insight. I'm curious whether or not speed shops are reputable sources to bring your car in to check whether or not a tranny rebuild is necessary. Do you guys know if this would be a good source? If yes, would they have the special tool that is required to work on the c60 transmission? Do you know anything in regards to pricing? I live in the pittsburgh area. Would there be any reputable shops and what would you all recommend?
