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.
