I have watch numerous videos and checking the forums (I am a new TJ owner) and I want to 1) change my transfer case fluids and change some leaky seals, 2) Change out my transmission fluid, 3) Change out my differential fluids and reseal. The transfer case is leaking at the rear output slinging fluid everywhere. The diffs are show signs of leakage and my transmission feels like it could use a refresh. The clutch seems good but shifting is sometimes not the smoothest. I think is could use some clean fluids all around. Is there a list on the forum I am missing for recommended fluids for these three areas? I want to do them right but I am a hard working American that has a budget at the end of the day. I may have to spread out the fluid changes over a little space of time but feel like they are all warranted. When I bought this Jeep it had basically set for 11-12 years mostly under a cover in a garage. So the fluids are old as far as age but not as far as miles driven (<3000). Just need some advice recommendations or pointed to the right "sticky" if I misses something. Input much appreciated!
