BTW,isn't it funny that this new stuff is backwards compatible all the way to the Dexron III only 722.3 and 722.4 units.

If this stuff really had some "special" additive package for the newer clutch packs that Dex III would cause to burn up then it's likely the newer stuff would cause more slippage in a Dex III application like the 722.3 and 722.4 but I bet that is not the case.
