iím not looking to skimp on fluid quality but not unlike motor oil grades, Dex VI is Dex VI... and then itís just opinions and experience after that.
For sure, and I wish I could give a personal recommendation of the fluid, but have not used it as of yet. I know that Nathan puts it in all high mileage BMW's with the ZF and GM transmissions. In his videos about it he says the ZF fluid is too thin and with the wear on the trans component seals, valve bodies, etc the Valvoline stuff helps to maintain pressures better.

But again, no personal, actual experience with it. I think in my wife's truck I'll use the Valvoline and see how it goes as the X35d also uses the ZF 6hp26.
