Even Dexron VI is getting pretty old in the design life. 2005! Its more shear stable during its life than III, and basically, I see no reason not to use it in your VD. I had VD with 350Hp driving them up to 4400rpm input. I changed VD fluids every other year, and these things just are not critical. The oil pump is not picky, the pistons are primitive, and it is just not a high tech, picky assembly. There are folks driving over 800Hp into these with only minor changes.
