My 98 forester kept overheating and was told the headgasket needed to be replaced. I took it in to the dealership and they said it would be ready in two days. Got a call from the service manager who wanted to know if I had had any problems with the transmission. Any hesitation, jerking, loss of acceleration. I said no, it's always had a smooth ride. Well when they put everything bakc together, it would not shift to drive or any gear. It's automatic. The manager said he had never seen this before, and that the only thing he could see was a dent on the transmission fluid pan, and has taken the car to a transmission specialist. I am very upset because I don't understand how the transmission could be messed up when they weren't even working on it. They also seem to be implying that I will be responsible for the repair cost. How could this have happened, any ideas?
