Dexron VI is backwards compatible to Dexron III. You can also find several brands of Dexron III/Mercon universal transmission fluid. I use it with good success in my Dex III applications. My last use was O’Reilly Automotive branded fluid. ---

I believe Dex VI is a full synthetic but I can’t believe Dex III is not available everywhere. ---

Dex III is very common, look again. ---

You won’t find a Dex III anymore - only Dex VI or the Dex/Merc multipurpose. Use the Dex VI if your original spec was Dex III. ---

I had the tranny fluid replaced with Dexron III last week in my GMC truck ---
