it goes back in the same drain hole it came out .
there is a special trans pump we use to fill them.
but I understand you far away from dealer
what you can try , is to buy a fluid transfer pump and get some hoses to fit the drain hole with some seals & gasket to make the connection
and pump fluid back in it .
Let me know if you need anything else on it , just reply back here & we can continue.
if you are good , Please Kindly rate me.
Hope I was helpful to you
