yep one at the top, if u have a big exhuast then u might have to remove some section IIRC, i think the plugs take a half inch braker bar, maybe its 3/8
anyway, with auto trans it gets a bit more complex as your best removing the sump, and changing the filter inside etc, if your not comfortable with it, id reccommend getting somone to do it for you, sorry for the quick replys im dead, any questions feel free to pm
also, when draining things like diff always crack the fill before the drain, because if you undo the drain and the filler bung is stuck then you have a headache.
