    I would asume that it takes gear lube but have seen lots of trucks that call for atf. /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/thinking.gif

    Cool,
    I was going to ask the same thing.So it takes 10w30? I guess i need to look at mine and change it, If behind a automatic it still takes motor oil right?

    neither, yes that is right I said neither, here is the break down on GM
    NP205- 90W gear oil
    NP208- ATF dextron III
    NP203- 20-30W motor oil

    Kinda funny huh? the parts dont lube correctly if you use 90W and if you use ATF they don't hold the lube (it is a hydro fluid not really an oil)
    afaik it is correct.

    thanx for the fix, that is why I threw in the "afaik" disclaimer. now I know farther. I was totally unaware of 205's using any sort of ATF, is it the slip yoke style or more of a point and shoot, random GM engineering game?

    It doesn't matter anyway. In the past on here we've figured GM did it for mileage. I don't know if it's exclusive to slip yoke models or not. My NP 205 is from 1979 so it uses gear lube.

    You could probably fill a 205 with beer or piss and it'd still work anyway, but I wouldn't recommend wasting beer or trying to put your wanker through the fill hole. /forums/images/graemlins/smile.gif

    it's gonna clog the oil throw and miss the nooks and creannies of the chain i believe. drain it and change it.
