Just over 12,000 miles on my 2005 Mustang GT and encountered my first problem: A slight lag when shifting into Drive. I took it to the shop and they kept it for NINE DAYS before fixing it. I kept saying, just give me a new transmission, but they kept breaking it down and rebuilding it until it was fixed. Not sure what the problem was, because the dealer said something about servos and a clutch plate and I just got lost. I have LOVED the car and it has been trouble free thus far but wondered if anyone else had encountered a similar problem on the automatic transmission. Or is this just a fluke (I hope!)
