I've seen many words change in meaning over my lifetime (ie, cool, bad, factoid, organic, gay, chemical, ect.). Perhaps if we use words that are not ambiguous, we wouldn't have this problem. The word "synthetic" is now ambiguous at best. If we want to know about base stocks, perhaps we should all communicate with terms like "PAO", "Gas-to-liquid", "severely hydrocracked", POE, ect.

I just happened to have my tranny flushed and filled in my '09 Malibu at the local transmission specialist shop. Highly regarded ... even dealers sub out work to them. Their 55 gallon drum is labeled SHELL DEXRON VI SYNTHETIC.

Right but even amongst basestock manufacturers, some may be better than others.
As this is a price point lube, the question is what has given? Its not a huge seller, has little shelf space, so likely doesn't have economies of scale on its side.
So what has given?
Or can we truly say that no name price point manufactured dex vi is the absolute same quality and performance across its lifecycle as a fluid from pennzoil or valvoline, for example?
Formulators and Blenders are given a set of GroupIII, 3 cSt, 6 cSt, and 8 cSt oils that are to be used with the Dexron VI PI package.
Looking at the formulation cards, there is little difference among the characteristics of the four major suppliers of GroupIII base oils.
This is good information, do you have any other information pertaining to ATF+4 like this?
Some of the members are having a hard time believing that all ATF+4 is the same if it's on the licensed list. From what i have seen they only have 1 PI package on the licensed list and there is very little difference in the base oils just like with DexronVI.

I believe the same goes for the ATF+4. Until specific ATF's becomes obsolete the way ATF+2 - ATF+3 or DexIII/Merc have become. Then this could all change!

ATF+4 approved products all use the same DI and the same VI which are both listed in the specification, base stocks are also restricted, so there is essentially no difference in performance between any of the listed approved products.
I only have one vehicle that callas for the Dex VI...actually, it called for Dex III, but I got enough recommendations on here to go to Dev VI that I did. It is a 2002 Chevy Trailblazer that had never had a transmission service (it was my parents'). I dropped the pan and replaced the filter and the 4-5 quarts that came out with Super Tech Dex VI. That was a year ago. Everything has shifted great since. This past weekend, I used a fluid extractor and replaced about 3 quarts--again with ST Dex VI. It was pretty dark, so it looks like it has been cleaning. Nevertheless, everything is shifting well. I plan to do another 3 quart exchange this summer.

At some point, you'll probably have done enough of a fluid swap that you can forget it for 100k miles or so. DEX VI holds it's vis incredibly well, and the oxidation resistance is outstanding. It can approach being a lifetime fill for some applications.

Cool--thanks! After I changed it out last year with 5 quarts and let it circulate it looked pretty red. However, after running for about 10 months, it came out pretty dark. At first I was surprised, but then I realized that the new additives added in were probably doing their job and cleaning/holding things in suspension. I think I'll keep draining/filling every 6 months or so until it comes out looking decent. Hopefully that only means a couple of more times. Unless of course Dex VI tends to get dark right away ANYWAY. I know sometimes you can't really tell much by the look of ATF.
