Today I went to the parts store to get an ATF filter & 6 qts of Dexron. The counter guy gave me the filter, & went to get the ATF, but apologized that they only had 2 qts left in the store. They were Dexron 6. But I told him since my car is a 05, Dexron3/Mercon was fine. He said his computer said to use the Dexron 6, but I said that started with 06. I said read the ATF jug, & ignore the computer. I then showed him 3 different brands of Dex/Merc which all said good up to 05. So is Dex 6 preferable in a 05 to Dex/Merc? Or is the Dex/Merc just fine? GARY

You will find that Dex VI is a full synthetic as opposed to Dex III which is not. Many here will tell you to use the Dex VI. I used Dex III last time I changed fluid and all is good. I am a little agaist putting a full sythietic in as I think it might cause leak or other issues in which it was not intended to be used. That is why I still use conventional engine oil, not synthetic. It's your choice. Both will work. Good luck choosing. Just never do a flush.
