First, does a NP208 have a vent tube? I thought for sure my manual said there is one but while I was under there I couldn't find one... nevermind, with a more elaborate search I found "Mr Red"s post about where it is. According to him it's on the top near where the halves meet. I wonder why I missed it. Anyway... What does water contaminated ATF look like in a transfer case? I know in a transmission it turns chocolate brown but I don't know what it'd look like in a transfer case (where there is no clutches mixing it up and heating it up). I turned my truck into a deep-sea submersible today and I crawled under there and cracked open the drain plug and the ATF was still as red as it's supposed to be. I don't want to go through the hassle of changing it if it's not necessary (since the fluid was changed within the last six months).
