one is for gm and mercon is ford now days they make a dexron mercon mix acceptable to both Dexron III and Mercon V have different specs. You should not use Dexron III in place of Mercon V.
Yes... Dexron 6 is the latest trans fluid and can be used in any application that calls for Dexron III
The major difference between SP iii and Dexron iii is the lubrication modifier. SP iii contains more lubrication qualities than Dexron iii. You can interchange the two but run a slight chance of premature wear using Dexron iii where SP iii is indicated.
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 Dexron-II has been replaced by Dexron-III.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.
Dexron III/Mercon automotive transmission fluid (ATF) is generally recommended as a replacement fluid for automatic transmissions meeting original equipment manufacturers (O.E.M.) performance requirements for current General Motors, Ford, other domestic and imported passenger cars, vans and light trucks where DEXRON II, DEXRON II-E, DEXRON III, AND Ford/MERCON fluids are specified.Dexron VI is a partial synthetic which properties exceed dexron III by 100% in every area. Dexron VI can not be interchanged or repalced with DEXRON II, DEXRON II-E, DEXRON III, DEXRON-III/MERCON.
Dexron III is itself an hydraulic fluid. The issue is, not all hydraulic fluids are equal in quality. General Motors recommends replacing the discontinued Dexron III with Dexron VI
dexron 3 replaces dexron 2, so you could mix them but the dexron 3 is better
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.
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 Dexron II no longer exists, as it was later superceded by Dexron III.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.
yes
dexron III or dexron IV can be used
Dexron III. You can Dexron, Dexron II, Dexron IIE, Dexron III, and Dexron V as suitable substitutes depending on availability. Lower numbers indicate a shorter lifespan of the fluid before you need to change it. Do no use Dexron IV (aka Manual Transmission Fluid) as this is likely to cause problems.
