Re: GM Auto Track II
That fluid is specifically for the AutoTrak series of Tcases. Those cases are "On Demand" boxes built by New Venture (NV), basically a standard 4x4 box with a big clutch that kicks the front output on and off. They're completely and totally different than the TCase thats in the Ty's and Sy's (BW 4472 which has a viscous coupling instead).
So, unless you're running a NV 136, NV 236, or NV 246 this probably won't help you. If it does, I'd be REALLY suprised, since the VC is a sealed unit.
BTW, Mopar has a very similar product. It was recommended by Rockland for use in my NV146 tcase when I put it in. Supposed to work better. Both the Mopar and GM products are expensive. (I bought the stuff 2+ years ago, and it was $11 and $14 a quart then). Maybe it's come down some.
