just look at the picture that Gary (devioustsi) posted on wnydsm. You want to unscrew the drain plug at the bottom of the tranny. It’s a 19mm bolt. Just unscrew it and let the fluid drain out, put it back in and tighten it and get yourself a funnel with a hose on it and fill it the right way (in the fill hole). About 3-4 inches above the drain hole on the “side” of the transmisson.
