looks like the transmission pan. The 700R4 did not come with a drain plug but their is a retrofit kit. And yes, their needs to be fluid in that pan.

I'd guess that it's the convertor cover and there's no plug there and there's no "retro fit or should there be fluid in that pan/cover". If it's oil you've rear main seal issues likely OR you've a leak top-side rear of engine and it's finding it's way to the vicinity. The other possibility is a front pump seal leak at the transmission. Which is it on the floor? ATF or engine oil?

no plug, that is the torque converter cover, it has a hole in it to let any oil that leaks out of the front seal of the tranny to alert you of issues. there is normally no oil or any other fluid in there unless you have a problem
