I returned the 80W-90 gear oil.
Went to W-mart.
I purchased Super Tech full synthetic 10W-30 oil for the transmission.
The 1 gal container reads "API service SN, SM, SL, ILSAC GF-5 and GF-4.
I believe that 80W-90 gear oil is GF-5.
The main difference that I have learned since my original post is that
Gear Oil (GF-5) is corrosive to brass or is unfriendly to yellow metal..the AX5 and AX15 trnasmission syncro gears are brass.
Manual transmission = 10w-30
For the transfer case I purchased Super Tech ATF
ATF label reads "suitable for use in vehicles requiring Dexron II, Dexron III and Mercon fluids."
Bought a Fluid Pump at Harbour Freight to make the fill job easy.

|hannahuffster||You actually can run about any lightweight oil in ether the trans or transfer case. The heavier (like gear oils) the oil the worse it is for both. I like ATF, but I also change mine 4-5 times a year because I am in a lot of mud and creek crossings almost every week...|

You want regular good ol' ATF in your transfer case. Don't go by what Chilton's says.
Additionally, Jeep has updated their fluid recommendations. Both the AX-5 and AX-15 now call for 10W-30 for the transmission. Regular dino oil will be fine.

Transfer case fluid
95 wrangler 2.5 manual transmission.
I am performing a drain and fill on the transmission and the transfer case tomorrow.
Im using 75W-90 (80W-90 actually) in both the transmission and the transfer case.
I have read numerous posts recommending ATF exclusively in the transfer case.
My Chilton manual reads: "Use the same viscosity oil as in the transmission".
But.. the next paragraph reads:
"Remove the fill plug, then fill the transfer case (both the NP-207 and the NP-231 use dexron II transmission fluid.")
Chiltons manual sort of contradicts its self.
Since my transmission requires 75W-90...thats what I plan on using in the transfer case.
If anyone has other recommendations, please let me know.
