GM and other Dex VI licensees compatibility listing is conflicting/contradictory/incomplete.Dexron VI is backwards compatible with any/every GM transmission ever made.
Superior to any previous fluid recommended by GM at that time in every way that matters.
GM says Dex VI is backward-compatible with SOME previous versions of Dexron, in SOME applications. It's NOT backwards-compatible with the early Hydromatic/Dynaslow that used engine oil, or transmissions that were specified for Type A, or Type A Suffix A; and early versions of Dexron. But again, info is contradictory/incomplete/subject to interpretation.
Non-GM vehicles that used Dexron may/may not be suitable for Dex VI.

Mobil™ DEXRON-VI ATF
Mobil™ DEXRON-VI ATF is a high-performance, synthetic blend automatic transmission fluid formulation designed to meet the stringent service fill requirements of GM’s DEXRON-VI specification.
(My emphasis) Mobil is claiming total backwards-compatibility with all Dexron formulas. That covers back to Model Year 1967. Prior to that, it was some version of Type A, and before that...motor oil.Mobil DEXRON-VI ATF is a high performance, synthetic blend formulation that meets or exceeds the stringent requirements of GM's DEXRON-VI specification and provides warranty protection for 2006 and newer GM vehicles. It also provides improved performance in older GM vehicles, wherever DEXRON is specified.
Another source saying Dex VI is only compatible with other Dexron applications.

I would be willing to put Dex VI into any Dexron application. I don't because I still have a heap of Dex-Merc (Dexron III-compatible) fluid; and nothing I own is new enough to require Dex VI.
