looks like the engine oil pan gasket needs to be replaced. by the color of the fluid I'm certain its motor oil.
trans fluid is unlikely to leak from there. a trans leak would be further back if input shaft seal, for example you'd see red fluid at the trans bell housing.

There are plenty of places to leak oil from so don't go ripping the pan off.
Check the oil level, confirm it is not over full.
Take the upper covers off by the fenders and with a mirror and flashlight examine the valve covers and feed tubes to the VVT on both sides.
After that you need to get it up on a lift and look with all the lower covers off and see where it originates from.
Take a peak here:
That feed tube seen behind the pulley is a likely candidate to leak while the engine is running. Inspect both sides..

The rear seal is the most likely candidate which is zero fun to replace.
I can't vouch for if it can be done in car and/if the 1st ans 2nd oil pan have to come off to replace it.
If it can be done with the pans in place, the least expensive repair is pulling the transmission.
If it is misdiagnosed, a big waste of time and money.
Have you had it on a lift to look up with NO splash guards in place?
These are not known for crankshaft leaks at the rear seal.
You best pull the starter and stick a boroscope in there to confirm. Well unless there is an inspection cover to be removed.

Remember, when you see oil in an area that doesn't necessarily mean that's where the leak is coming from...I've had leaks from valve cover gaskets that dripped down by the oil pan.

IMO even if the motor is at 200k it doesnt warrant an engine swap. Oil leaks are relatively easy fix and far less expensive then say sourcing another motor and trans. Like others suggest, if you cant confirm where the leak is coming from, taking it to a mechanic would be your best bet.
