I have a 02 f250 auto, I had my tranny serviced. The flushed the system and changed it to merconV. They said this was better and would be ok.My dipstick says use mercon. Am I going to have trouble using the merconV?

Thanks
Dennis

 

If they flushed it, no. There was a lot of controversy over this a while back but it seems that there was no probs according FOMOCO who owns the rights to mercon.

 

well, ford does not rate Mercon V as safe. there are some parts of the transmission, i believe the clutches or something that cannot hold up to Mercon V. im kinda "in the dark" on this except for knowing that it's not recommended for use. i have heard some people using it and doing fine with it. it all comes down to how fat your wallet is, if you have money to spare for a new transmission.

 

there was some early controversy... lemme look into it

 

Yeah, you'll be just fine. no dramatic differences worthy of noting. just continue to USE the MV now.

 

As of July or Aug of 06 the formulation of merconV was changed and is no longer detrimintal to our clutches

 

man, what a . thats news to me.

 

I may be new, but I guarantee you it is here, only, lol.

 

hmm, now how did this newbie double-post this with a post in between. im useless.

 

A posting fiend should know these things.

 

There was a TSB on it I read on the "other" forum you still have to do a full flush to use it though

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.

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.
