Transmisson fluid leak, can I get a schematic for the car's hydraulic system?

It had a transmission fluid leak last week; it seemed like a hose burst or seal broke, and it started leaking out and made a mess in the rear part of the engine bay. I was hoping there was some kind of schematic for the car's hydraulic system so I could see which lines are for transmission and where to look. The area is very hard to get to and see without taking the engine out. And I don't want to take the engine out.

I know it is not an oil pan leak as the mess is just under the head gasket of the engine. It's just at an angle where I can't see anything.
