I was driving my car, and I felt a bang like I hit something, but I never saw anything in the road either before the noise, or in the mirror after the noise. At the time I thought it must have been a piece of rubber from a tire. From the sound and vibration I thought it hit the drivers door and maybe left a dent. I drove another 150 miles, and when I stopped, there was no mark on the door, which was good news. However, after letting the car idle for 5 minutes, there was a large puddle of oil under the car, which turned out to be the transmission oil. I had the car towed to a shop (nothing like being 400 miles from home with tranny trouble right?). They put it on the rack and told me that there was a big dent in the bottom of the pan, and that the oil was coming from around the gasket. They couldn't tell me why it didn't start leaking till after I stopped, but that's the case. Shop bought a new pan, and replaced the filter, gasket, and oil. and 2 weeks later I drove the 400 miles back to the car and picked it up. I went 30 miles to a hotel and the car seemed to shift and transfer power fine, but when I came out in the morning, there was a big puddle of oil under the car. Had the shop come back and get the car the following Monday (did I mention how much fun it is to have a disabled car 400 miles from my garage and tools?). They called me 5 days later to tell me that this oil leak appears to be coming from higher up in the transmission (he suggested a leaking pump or line?). I don't have any pictures and they told me that the oil runs out very fast and the car would not be drivable. They said that this is not their kind of thing and they wouldn't attempt repairs on the new problem. As I am not too familiar with the working of the transmission on my Passat, I was hoping that someone could tell me if I am screwed, or if there is some place else that the oil could be coming from?
