Transfer Case fluid

[Texas Gringo]

I have a 92 & 93 YJ. Both have 5 speed I6 diive trains. Do they use the same transfer case fliids and if so what do I use?

They should both have the NP 321 transfer case from the factory. You should only use ATF.

How about Mobil 1 Synthetic?

Synthetic ATF should be fine. I use conventional because it's cheaper.

Ditto on the Automatic Trans Fluid. Synthetic is IMO a better choice, albeit more expensive but it should also last longer before it breaks down. I belive the NP231 should take 3.2 pints.
