Dexron-III/Mercon (D/M) does NOT meet the Mercon V (M-V) or Dexron-VI (D-VI) rating and should NEVER be used in a transmission that requires M-V or D-VI. However, M-V and D-VI both exceed the D/M spec and can be used in a transmission that calls for D/M Transmission Fluid. Despite this, there is really no point in using M-V or D-VI in a transmission designed to use D/M because those transmissions do not get any added benefit from them despite M-V and D-VI being roughly double to triple the price of conventional D/M.
Yes . . . All dextron iii applications can use mercon v
Yes . . . All dextron iii applications can use mercon v
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.
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 /mercon
Mercon/Dexron III
Mobil 1 ATF formulated for Mercon/Dexron III is good, but anything that is certified as "Mercon/Dexron III" compatible should be ok.
Mercon, or Dex/Merc, or Mercon V. MOST fluids marked Dexron/Dexron III are also Mercon certified.
You want to use MERCON V transmission fluid. Do not use MERCON/DEXRON III as this older version is not formulated to operate correctly in your transmission. The bottle must clearly specify MERCON V which has superceded the older MERCON/DEXRON III formulation.
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 Dexron-II has been replaced by Dexron-III.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.
Use any good quality MERCON V Fluid. The old specification specified MERCON / DEXRON III However, a TSB issued a few years ago specified that MERCON V fluids superscede, and will replace MERCON / DEXRON III.
