Oh and how could I forget this gem the mechanic told me: after he "fixed" the shutting off, he said that he disconnected some vacuum lines and that made it able to turn off with the key. As I was driving home I noticed that the car was not shifting as smoothly as it had before. So, I went back to him and told him about it. And he said:"oh the vacuum doesn't have anything to do with the transmission!" I thought REALLY??? OMG!!
