I got an oil pressure warning light in my 2009 Honda Fit Sport and discovered that something had failed and emptied the contents of the oil pan onto the top of the transmission. I removed the air box and found oil pooled in spaces atop the transmission below the transmission shift solenoids; the whole bottom of the car is soaked.
I can find no obvious source of the leak and have no idea what oil sources could have failed in that area. Is there a high pressure line exiting the block or head that could cause this? I have no manuals and have been unable to source a diagram of the oil system in the car.
Can anyone help here?

 

When you click on the 2nd Gen page on this forum, the repair/shop manuals are stickied at the top of that page. You can source them there.

To start off with, have any repairs been done to the car recently? Has the oil/ oil filter been changed recently? Could the oil filter have come loose? Do you have any history on the car ie had the car for years vs just bought it? The answers to these questions could point you in some direction.

With the air box removed, it would seem that if the oil is pooling on top of the trans, that if you could safely re-start the car briefly you might find the source of the leak. That could be done after making sure there is sufficient oil in the engine first.

 

In complete agreement with @56chevydan
When it comes to finding leaks start at the highest seam/line/whatever that shows residue on your engine and work your way down. The engine's oil stays in the engine, so there's no high pressure line, but a clogged pcv valve could cause pressure to build up significantly.
