Changed the transmission fluid, transfer care, and rear differential fluid. I was going to do the front but the diff cover doesnt have a drain plug so I wasnt prepared to pull the cover off and reseal it. The fill plug also requires a large allen key that I dont have so I may get to that this Friday. The transmission fluid didn't look too bad. Had a slight tinge of brown to it but was mostly red still. The transfer case was pretty dirty and had a large amount of metal shaving on the drain plug. No big chunks so for now I'm good. The rear diff had some white milky fluid in it which I am assuming was water but once that drained out it had a nice purple color to it. AFT synthetic for the transmission, Master Pro Synthetic 75-90 for the transfer case, and Master Pro 80-90 for the diff's. I'll probably change out the diff fluid every 30,000 miles or after deep water crossing so I didn't bother using a synthetic.
