MP5 auto trans fill plug

Hey guys, so i drained my atf and removed the oil pan also changed the filter but now i can’t find the fill plug, i’m wondering if there’s even one i have a 2002 auto mp5 and i didn’t find one in the manual, someone knows anything about it?
 
I gently poured mine down the tube using the dipstick to wick it since I didn't have a funnel narrow enough. saved me a trip to the store just for adding half a qt.
