First place to start in any situation like this: catch breath and let frustration clear out! Had to do that twice today. ;D
You can't do much worse than to crawl under the car and take a look. Maybe let it idle for 30 seconds or so while looking to see if that forces any more fluid. Hopefully it's the pan, as any other way sounds like another transmission pull. Fingers are crossed for ya!
The day you stop learning about this car is the day you're no longer an enthusiast.
