If it was water pump, that would explain the grinding and the leak perhaps...though if it was starting to overheat coz of wp blown up, also, since I guess you have an auto, I don't know how heat might affect it...since it does have a cooler...which I guess would work less well if wp blew up.

Other grinding things? You maybe have a coffee grinder plugged into an inverter, which you rigged under your cupholder but just forgot about?

So you were thinking trans. coz of where you were sure sound was coming from...nothing in the drive itself?

i totally forgot about that coffee grinder!

my car is a 5 speed though. and i didn't thin about the wp but it only grinds while it is in gear and moving. i couldn't find the leak tonight but it looks like its coming from under the engine. and yes i was thinking of the trans because of where the sound was from but im thinking not now because it shifts seamlessly and quietly and since it only grinds while it is in gear moving and doesn't slip at all it could be the drive. still doesn't explain the magical coolant leak though, but they could be unrelated and i am just that lucky.
Stupid f**king plastic parts!
