What are some common oil leaks to look out for on these cars? I'm loosing transmission oil somewhere. I degreased and pressure washed down under already. On the back side of the oil pan, there appears to be some type of splash guard w/ 2 plastic mesh squares. (sorry for poor terminology.) Anyway, what's underneath that piece of metal w/ 2 plastic mesh squares?

What you are describing with the mesh squares is the bottom of the automatic transmission's bell housing. Directly above this is where the torque converter is located.
The usual trans fluid leaks would include:
→trans cooler lines, right where they connect to the side of the transmission
→rear output shaft seal, usually the bushing wears and then the seal will leak, so you want to replace the bushing if the seal is leaking
→front torque converter seal, this would be a rare failure.
→sump pan, usually due to loose or missing hardware
As for the engine, normally they are very minor on the non turbo engine:
→valve cover gasket
→dip stick tube o-ring at the block
→camshaft oil seal
→crankshaft front oil seal
→crankshaft rear oil seal (a rare event)
→sump pan, normally due to loose or missing hardware
→head gaskets can also leak (a very rare event)
Any blockage in the PCV system can cause excess crankcase pressure which may lead to oil leaks and seal failures.

Thanks. I took the part of the bell housing off and found this:

I assume I need to replace the oil pan seal, right?

Hard to tell just from those photos if it really is the sump pan gasket, but odds are you can just tighten up the bolts. I've never seen one that "had" to be changed except where the pan bolts were over tightened and that distorted the bolt holes so that the pan was no longer flat.
