Re 1999 Toyota Avalon XLS 3.0 V6, OM calls for Dex 2/3 ATF. A couple years ago I replaced with Dex 6 when I could no longer find Dex 2/3. I have been happy with Dex 6 and so have others based on several posts on various Toyota forums. However, recently I have read a couple posts where people say Dex 6 is not right for my transmission. One person even contacted Toyota and claims Toyota said they do NOT recommend Dex 6 for my car. So what should I do? Ditch the Dex 6? If yes, what should I use? RP multi-spec, M1, etc? Thanks.
