200k mile 4l60
now my question is, is the Dexron 6 ok to use on my car with this many miles? Obviously the dex3 was phased out and I heard the dex6 is a syn blend but it's a tad thinner than dex3 but just lasts longer won't break down as fast yada yada... Would I have any issues using the dex 6?
Sorry if this has been answered a million times
