The Stovebolt Site Forums The Shop Area Driveline T5 Clutch?

I don't quite know what to make of this found last nite: from gmpartsdirect.com "any vehicle that uses Dexron lll for manual transmissions - should now use PN 88861800 Manual transmission & Transfer case fluid". I suppose it's specifically formulated for our T5 WC applications that require ATF? Type lll back comparable to Type ll, which is what we can't find.
