1993 Chevy 2500 pickip
Back in 1993 your truck used Dexron III, so if you bought it today, you would look for DEX/MERC, but Dexron VI will work as it's backward compatible.
Dextron III or better. I don't even think they make Dextron III anymore so Dextron IV. Now this is for an automatic transmission.
