Regardless of brand, DEXRON VI is superior to III, and it is synthetic only. There will be no difference in performance, however.

Cool so whats best to switch to DEXRON IV or stick with the III, i see the IV is a little more expensive is it worth the cost?

Weather or not it's worth it, is up to you.

GM changed to all DEXRON-VI in mid-2006. It is now used as replacement for ALL obsolete DEXRON-III.

Exactly the same as - when your car was built the API engine oil service designation was SL or SM - those are now superseded and engine oil on the shelves is service SN.

Then go with VI.

Not sure you can even buy III anymore.

I believe the dex3 name sort of went away. U can buy trans fluid that meets dex3 specs now. Label says so. I assume there is a market for "universal" trans fluid.

I've had great results with Mobil 1. I'd personally pick that.

 

[Submariner409]

There is a LOT of DEXRON-III on parts shelves around the world. As far as the "universal" transmission fluid thing goes, DEXRON-III and DEXRON-VI are 100% compatible and mixable frontwards and backwards.

If you mixed X quarts of -III and X quarts of -VI you would create your own "synthetic blend".

Dexron 4.5? :hide:

Just dropped the pan this weekend and swapped in 4 qts of the valvoline dex/merc, 2.5 qts of the maxlife, and some lubegard red. Made a smooth transmission shift and drop into gear even smoother.
