LeSabre in Buffalo is on a distinguished road
Default Dexron-VI ATF

I searched and did not find anything about Dexron-VI ATF. Have people used this, and what was the experience? I'm thinking of doing a change soon on the LeSabre, and wondering if I should use the "latest and greatest" GM-spec ATF.

It'* ATF and your trans will still work just fine.

Just like it would with Coastal brand or any other generic store brand.

There was a guy on the LeSabre board that used it. Expensive stuff at $6 a bottle...

But it supposedly cools, lubricates, and keeps parts cleaner than earlier versions of ATF. Keep in mind the 4t60 (AKA 440-T4) used in the LeSabre T Type was designed with dextron-mercon II in mind which doesn't even exist anymore since technology in fluids has advanced.

Anyway, the guy that tried it said he felt much smoother shifts and quicker acceleration. Granted he changed out old fluid, but I don't think the "old" fluid was particularly bad.

Granted there is no way to actually proove seat of the pants results without a dyno.

Personally, I probably wouldn't spring the extra cost per bottle for it. I did buy one not too long ago just to see what it was like and it seemed to flow just a tiny bit thicker than Dex/Merc III but otherwise everything else seemed to be the same.

I guess my point is that it *might* help, but not enough to bother with in an ordinary trans on an ordinary driver car designed with the older stuff in mind anyway.

I'll switch when Dexron VI has "trickled down" to the Wal Mart SuperTech line
