Thanks for the pictures and info. Yes I know what you mean about hydrolics. The tank above the rear end is separate on mine so now I have to fill that as well. I have 3 drain plugs; one for the rear end which does just about everything, one for the 2/4 wheel shift and one for the shuttle shift. I pre-filled the first 2 compartments then closed them and filled the normal way through the dipstick. I now have waited overnight and will check this morning again to see if I have to add more which I'm sure I will. I hope with brand new oil and putting things back together carefully and tight that the occasional "clunk" disappears.
