I am a 5.0L newbie. I started finishing putting together my brothers mustangbecause he abandoned it. On the automatic tranny, on the passenger side there is a hole about 1/2" or 3/8" , it is locatedfront on top of the lip of the auto tranny fluid pan. Is that the tranny fluid filler hole? Does it have a plug or is there a dipstick that goes down there?

Yes, that is the location for the dipstick tube.
