You are looking at an inspection hole on the transmission bell housing. The oil drain plug is just2 to 4 inches in front of that. Do you KNOW what you are doing?
Im pretty sure you are looking at the wrong thing. Ive never heard of that and a few of my friends who have worked for oil change outfits have never mentioned one.
