water dripping on the garage floorfloor under trans 3.2 eng.

What is your question?

I notice water dripping on the floor after parking the car.I raised it up and looked to see where it was coming from and I see the water leaking out some sort of a funny looking small ( black) plug.with a small hole in it like a drain.Its above the exhaust and transmission (heat heat shield.). Is this the a c condensate drain???? I hope so.I just had the radiator replaced and trans,fluid checked and topped off because of cooling lines leaking at the radiator the mechanic told me there are no other leaks under the car.Its all dry.
