Bad info. Here is the FAW from Valvoline:

Does Valvoline make a synthetic ATF?
Yes. Valvoline makes several synthetic ATF's. MaxLife Dexron/Mercon ATF, Mercon V ATF, ATF +4 and Dexron VI are all synthetic.
Also, they changed around June of 2010 according to the posts that starting showing up here. IF you want to older stuff go to an Autozone and look at the back of the shelf. The newer stuff should be fine and it is backwards compatible.
My newer GM transmission shifts nice with it, but I also added a bottle of Lubegard too. I did have some quirky shifting behavior over the winter when it got colder, but it was only a small range of temperatures and I then added the Lubegard.
So Maxlife should be safe for an older transmission?
I was looking at the back of the Pennzoil HM Tran fluid bottle, and it states as a HM ATF, it will condition the seals and help remove varnish and build up....this sounds like a bad thing to me....wouldn't it be better to keep the varnish in place?
The back of the maxlife makes no claims too remove varnish.
