I've read quit a few threads about leaky butt and side shaft seals and pan leaks, but I think this is different. I had to move the 2000 from one side of the garage to the other to make room for a new project. It was about 40 degrees at the time. When I got out of the car there was a puddle about 6 inches in diameter from where I started and a stream from there to where I backed up, about 30 feet, and then back to where I parked it. Put cardboard under and had another 4 inch puddle and then quit. So it seem to come out only when running. I have not raised it to look for obvious reasons, but if some one could point me in the right direction on what I might me be looking for would be great. Had the car for a year and never had any leaks. Thanks

 

You'll only find the leak by getting the car up on a lift. Not sure if this will help but I'd still suspect the output shaft seal. Its 106 on this picture. Theres a good summary of a DIY change in the archive. Mine was replaced under warranty but it's not a job I'd tackle
