Ok, so this is the second time i've taken off my driveshaft and of course some ATF fluid comes out of my tcase, i want to put it back in but im not sure if i was trying to open up a plug, i was trying to undo what appeared to be the plug on the top of the back of the tcase and i assume the drain plug is on the bottom. Anyone know what exact size socket that thing is? i tried a milion different ones and nothing worked, it didnt budge. So was i playing w/ the wrong plug or what?
