Is the latest the greatest?
Dexron VI is considered backwards compatible, based on current readings on the ATF. It’s the only licensed fluid GM has with it’s producers. Dexron III and prior are no longer licensed. Therefore, producers have consolidated the formulation of Dexron and Mercon to support “multi-vehicle” use. For me, that’s like combining two half empty whiskey bottles from Jack Daniels and Crown. I cannot find Dexron III specifically. 1) is there a source? At the time Billd wrote the sticky, I believe Dexron III was specifically available. Can we use Dexron VI, which is manufactured for tighter tolerances? Can we use the blended Dexron/Mercon? Can we update the sticky? |

Based on the stuff I have read I think Dexron IV and above are not backward compatible to the older formulations. I will be dealing with this issue very soon myself as I try to find Dexron III for my Classic fluid and filter change.
