Mercon V

[NYC4X4]

I have a '95 fsb 5.0 5 speed. In a bit of speed shopping at pep boys (too many things to do on a sunday...) I grabbed mercon V and used it in my transfer case fluid swap. Its' Penzoil mercon v and it says it can be used in all ford vehicles that require mercon or mercon v. YES I SEARCHED but I got a few conflicting answers so I figured I would post one definite question:

Is it ok to use Mercon V in a '95 transfer case?

What about the tranny - going to do that next (I have the mazda 5 speed)?

Thanks!

according to FMC, mercon V has replaced Mercon and is an acceptible substitute.

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.



PART NUMBER PART NAME

I use the synthetic version in my t-case. The temps get insane and well above the rating of dino tranny fluid. Plus, they only hold 2 qts.

Do you have any objection to my reposting that in the TSB thread?

Steve, no problem, go ahead. This is why we are here, to help each other out.

[imlikeojnow]

Man it is good to know that Mercon V can be used. It is getting harder to find just mercon or mercon 3 anymore. Thanks for the TSB.

Now will mixing this affect anything cause i have mercon in mine now?

[NYC4X4]

Thanks! I appreciate all the info. Now to swap the tranny fluid. Thats if I can find a funnel that looks like a crazy straw to get the fluid into the fill hole. Not exactly the easiest place to empty a quart bottle....

Thanks again. This board rules.

[imlikeojnow]

hahahah you got to get one of the funnels with the plastic flexible thing on the end of it at wally world for like 5 bucks or so

[matt4068]

so im probably mistaken but dont we have conflicting information ???

steve83's link states : " MERCON® V Automatic Transmission Fluid: Engineered and recommended by Ford Motor Company for use in automatic transmissions ONLY where MERCON® V is specified. "

and

92builtbronco's info states : "ACTION:
Beginning immediately all automatic transmission / transaxle applications requiring MERCON® can now be serviced using MERCON® V or MERCON® Automatic Transmission Fluid "



so am i just reading this backwards ... or wtf??? im already loosing it because taxes suck and are confusing.

[Handy_andy_cv64]

Find a parts store that sells fluids in quart or gallon jugs with a hand pump and hose. My coworker has a quart bottle with a pump and hose that we use for pumping ATF into manuals and xfer cases.

anyone?

[Steve83]

The TSB is a later publication, so go by it. IDK when they last updated that fluids page.

[sewiv]

Most Walmarts will also have long straight funnels that work fine for filling the transmission.

[GTRider245]

Or try a fluid pump

[adrianspeeder]

Only the NEW "reformulated" Mercon V is supposed to be used in the E4OD/4R100. Unfortunately there is no way to tell the new from the old other than the bar codes, and I have yet to see what Ford did to "reformulate" it for compatibility. It was rumored that people saw Ford taking back all the old Mercon V from stores and spot checking the bar codes to make sure only the new stuff was sold when that TSB came out.

The M5OD-R2 and BW1356 ain't gonna care, but I'd be worried about E4OD/4R100 owners.

Mercon V was originally made 4 years after the intro of the 4R70w because plain ole Mercon which doesn't have friction modifiers. The 4R70w needs friction modifiers, but the E4OD/4R100 is designed not to have friction modifiers in the fluid and there are many reported cases of the E4OD/4R100 dieing after the old Mercon V was mistakenly put in.

In conclusion, who the hell knows with Ford. I'd just like one hour to talk with a powertrain engineer there.

[92builtbronco]

Adrian, the powertrain engineers don't know which end is up half the time either.

[amraam840]

oooo, good read. I'm I saw this cause I just bought a case of Dexron III / Mercon and I gotta ask how that'll do. I got it to change the fluid but the stuff that's in there is still bright red and clear, but that's what the dipstick shows. I wonder what's lurking down there in the pan?

So how's the Dexron III / Mercon gonna do me? Should I return it?
