    Look on the back of the t/case for a round plate with numbers on it. If its a 246 than you have to use GM auto-trak II. I believe all others use automatic tranny fluid.

    NP246, or if you have a Auto4wd button, you need to use GM's Autotrac2 fluid. Otherwise your best bet is synthetic manual transmission lube.
