ATF which type

Looks like DIII/Merc is going away. Should I use Dexron VI/Mercon LV or Mercon V. I guess 6 and LV is newer than V? Also can I mix these with the DIII that is in there? I sent the wife to Walmart this morning to get some DIII and they don't have it.

Thanks

Perry

Mercon has been dead for years now, the proper fluid is Mercon V. Don't use any LV, ULV or SP rated fluid.

Perry, back in June of 2006, Ford issued the following TSB. Subsequent to that, Dex III/Merc did indeed disappear from the shelves. A short time later (maybe a year, I can't remember), it reappeared on the shelves, however it no longer carried the proper licensing on the bottle from Ford, because now only formulations meeting Ford specs for Mercon V is licensed.

This article supersedes TSB 01-15-7 to update the vehicle application chart.

ISSUE:
MERCON® Automatic Transmission Fluid is being replaced by MERCON® V as a service fluid.

ACTION:
Beginning immediately all automatic transmission / transaxle applications requiring MERCON® can now be serviced using MERCON® V or MERCON® Automatic Transmission Fluid or dual usage fluids labeled MERCON® / MERCON® V. After July 1, 2007, MERCON® Automatic Transmission Fluid will no longer be manufactured, therefore, availability of this fluid will only continue for however long it takes to deplete what remains in inventory.

SERVICE PROCEDURE

Service automatic transmissions requiring MERCON® with MERCON® V or MERCON® Automatic Transmission Fluid or dual usage fluids labeled MERCON® / MERCON® V

For proper fluid application on current and past model vehicles equipped with automatic transmissions / transaxles refer to the fluid usage chart. (Figure 1)

CAUTION: AUTOMATIC TRANSMISSIONS / TRANSAXLES THAT REQUIRE MERCON® V SHOULD STILL ONLY USE MERCON® V OR DUAL USAGE FLUID LABELED MERCON® / MERCON® V.

CAUTION: MERCON® SP, MOTORCRAFT PREMIUM AUTOMATIC TRANSMISSION FLUID AND MOTORCRAFT M5 ATFS ARE UNIQUE FLUIDS AND MUST BE USED IN APPLICATIONS RECOMMENDING THAT PARTICULAR FLUID. USE OF ANY OTHER FLUID MAY CAUSE REDUCED FUNCTIONALITY OR TRANSMISSION DAMAGE.

CAUTION: THE FUNCTIONAL CHARACTERISTICS OF FLUIDS FOR CVT TRANSMISSIONS ARE VERY DIFFERENT THAN THOSE OF OTHER AUTOMATIC TRANSMISSION FLUIDS (ATFS). USE OF A FLUID OTHER THAN MOTORCRAFT CONTINUOUSLY VARIABLE CHAIN TYPE TRANSMISSION FLUID OR ONE LABELED AS MEETING MERCON® C WILL CAUSE FUNCTIONALITY CONCERNS AND INTERNAL TRANSMISSION DAMAGE.

CAUTION: DO NOT USE AUTOMATIC TRANSMISSION FLUID SUPPLEMENTS, ADDITIVES, TREATMENTS OR CLEANING AGENTS.
