    I wonder if GM P/N 88861800 is conventional or synthetic?

    Looking through the Valavoline specs it seems that the Valvoline equivalent is intended for manual trans only. I know the GM fluid (GM 12345349) I used to put in my NV3500 didn't look or smell anything like ATF.

    Not sure if it's synthetic or conventional based, but I think the 88861800 is basically Dexron 3 in a different bottle with some other additives. If you check the contents on the back of the bottle in that Amazon listing the first thing on the list is "Automatic Transmission Fluid."

    I would assume so, I stick to GM fluids so I have no experience with it personally though.

    Dexron VI has a lower viscosity that Dexron III, and I assume that's why they didn't want it in transfer cases. None of the benefits of VI listed in that bulletin matter for a transfer case.
