Transmission fluid everywhere

Bringing the car out for a wash earlier today the transmission dropped her fluid. Car was in park and I was turning her over when it happened. I have no idea what part of the transmission the fluid came from. I thought I had blown a line, but they are still intact. It looks like the fluid came out of the of the hole in the inspection cover. That area was covered in more fluid than usual. The outside of the transmission pan gasket was a little wet, but not drenched. I don't think it came from there. There was fluid on the bottom of the headers. I think that was from it splashing off the floor. I checked the transmission dip stick and it was dry. I am going to try and schedule an appointment for a shop to get under there. I probably need them to drop it and go through it to make sure its good to go. I have know idea when the last owner had it worked on. Anybody got an idea on what broke? I know the pictures aren't great, but it took me a while to get the fluid up. It ened up being a puddle the width of the car going from the front wheels to the rear wheels.
