I am getting really frustrated with the GM dealer around here. They can't diagnose my idle problem I have been having for three years and now I bring it in for this problem and the transmission technician stalls my car 3x trying to get it to go. So he asks me if its a stock clutch and I say no. He responds with, "Its a clutch problem." I asked him what it could be and got the same response. Then later tells me my clutch (Stage 1 Exedy, I believe, from Turbo Tech) is not meant to be used in stock cars and that is why I have problems. My opinion on the matter is he was just annoyed that he couldn't drive the car and started blaming it on the part because it was not GM. Now, yes, he is a transmission tech so I am sure he is very good at working with car but when he can't drive the car, hears the clutch isn't stock, and immediately blames my problem on that without being able to even give some kind of direction to me what kind of "clutch problem" it is, to me it seems like he just is looking for the easiest scape goat. I don't why pretty much every person at this dealership treats me like I am dumb. Too bad they are the only GM dealer in town.
