Yes
If it is a A/T Powerglide, you can use Dexron or a synthetic such as Mobil 1 ATF. You may not be able to find Dexron, but you can use Dexron II or Dexron III.
Dexron III
Dexron-III
Dexron iii
You must use-- DEXRON III Trans. fluid
Better or not, really isn't the question. Dexron-II has been replaced by Dexron-III. Any transmission that used Dexron-II can now use Dexron-III. Fluids labeled Dexron-III/Mercon are also acceptable.
If it is an automatic transmission, Dexron III or Mercon are both acceptable.
All GM cars use Dexron transmission fluid. It may say Dexron III or Dexron VI. You can put either in your car. It used to be Dexron II, but they stopped making it so you just use whatever Dexron currently is on stores shelves. It's fairly common. Dexron III ATF (Automatic Transmission Fluid).
Honda originally specified Dexron II for that transmission. Dexron II no longer exists, as it was later superceded by Dexron III. So, use Dexron III. You will frequently see bottles of ATF that say "Dexron III/Mercon" or "Dex/Merc" for short. That's the stuff to use.
Use Dexron III the same stuff you would use in your automatic transmission.
Dexron, whichever is current. It used to be Dexron II-E then Dexron III, now it's Dexron VI. Just ask for Chevy automatic transmission fluid at your local auto parts store and you'll get the right stuff.
Dexron III can be used and you can also use the newest Dexron VI which is backward compatible and provides more protection than Dexron III.
