Dex VI is basically just synthetic Dex III. If you don't know what's in there now, I would just be adding in Valvoline MaxLife ATF. It is compatible with either and meets the Dex VI spec. You can get it much cheaper at Walmart than you can from the auto parts store.The guy at Autozone told me dex 6 n they only had full synthetic..the trans is Rebuilt n the guy before me put some fluid in but i dint know what cause he passed n never drove it yet...i hope i didnt screw it up ??i only put 1 gal so far cause im trying to figure out how mych he had
Edit: apparently the Forum doesn't like the amazon links right now... you can search for Valvoline Dextron VI or "Maxlife ATF" and find them pretty quick
Does that vehicle have shift adaption strategy functional in the computer?I only run DexIII, I ran the DexVI for about 10-15 miles once, but my 4L85E did not like it, I removed a cooler line and flushed 4 gallons of DexIII through it and it went back to its normal old clunky self. With the Dex VI in it, it was shift flaring and felt like it was going to slip itself to death in a short period of time.
Perhaps a moderator will move this thread out of ENGINES and into "Transmissions".

Wondering if the thinner Dex VI would have changed the shift adaption if you'd left it in there for a few more miles.
ATF Is backwards compatible so putting Dex 6 in is not a problem.The guy at Autozone told me dex 6 n they only had full synthetic..the trans is Rebuilt n the guy before me put some fluid in but i dint know what cause he passed n never drove it yet...i hope i didnt screw it up ??i only put 1 gal so far cause im trying to figure out how mych he had
