you can get a hose from autozone or pepboys that screws ontop of the mtf bottle and it has a twist on\off valve. There is a hardened plastic tip at the end where you put it in the fill hole of the tranny and add the oil. Redline's bottle doesn't fit the one i have so i put a funnel at the end end just fill it from there. If you want some pics lemme know I can show you what it looks like.
