Mike, Forget this guy. He sure doesn't sound like anybody I would want working on my stuff. He may be the tranny guy at a dealership but I'll bet he's nothing more than a glorified parts changer. Call John, at All Metro Transmission. He's the owner. On Clyde Park just north of 44th. Good guy. Knows his stuff. Tell him I recommeded him. I don't know if he will cut you a deal because of that but he will do you right.
Good Luck, Doug
