Hi, i have a 1989 S-10 Blazer, 4.3L. Automatic. This may sound like a stupid question, but do i use Dexron III in the tranny? I know the owners manual calls for Dexron II, but isnt that the same thing as III? Isnt Dexron III just an updated version? Let me know.. i just wanted to make sure.. thanks

Yes Im about 99 % sure you are right. Use dexron III. I did a trans service on a friends old 3.1 liter lumina, the owners manual said dexron II also.

dextron III is an updated dextron II. as far as i know (not much) they added more lubricants and a little better heat resistance to the mix. i cant find dextron II any more in the parts store and when i ask around (even dealer) dextron III is the same.
