is it auto or manual cos if its manual there will be a level plug on the side of the box so ya's need to slide underneath the car and looks up once ya found it undo it on level ground then stick ya finger in and see if it gets oily also you fill it up thorogh this hole and as for draining it there should be another plug on the bottom of the box. Also same with transfer box. manual box use ATF dexron 111 and for t box use ep80. hope that helps that is if its a manual box if its an auto then some one else will afta elp ya
