Yes, I used to think that was a plus. That was until I found issues with backward compatibility for Dexron 6 for my trans. Actually, this reminds me to post something on this over on the ATF forum. I guess I just wonder how much true "testing" is done when claims of back-specked fluids. Maybe they conduct extensive tests, but I found the spec lacking for the latest Dexron. Just my experience with one vehicle, but it does make me wonder.
