I have just purchased a 2000 F350 lariat 4x4 supercab long bed psd with an automatic transmission. The truck has 80k miles and I am doing all of the maintainance on the truck. I have seen mixed answers on this forum as to which transmission fluid to use. I have seen people say mercon V and I have also seen people say mercon sp. I have also seen different names for the automatic, e4od and 4r100.
Which fluid should I use?
What transmission would be in this truck?
Thanks for any answers
Please don't bring this topic up again!!!! If I didn't convine you by my replies in the other thread, fine, put lemonaide in there for all I care. Your manual clearly says ONLY TO USE MERCON, and THERE IS NO PROOF OF ANY REFORMULATION, fact not fiction. I'm not going through that thread again.
Good Day
Not trying to argue with you so please dont yell at me if you get upset with what I'm going to say. They stoped making mercon.. They released a bullitin from Ford saying they no longer produce it and everyone should use Mercon V and they enginered it to work with all Mercon required transmissions. (One thing to the starter of this thread DONT USE MERCON SP it wont be good trust me.)
A/T - Mercon V ATF Usage
TSB 06-14-4
07/24/06
MERCON ATF IS BEING REPLACED BY MERCON V
ATF AS A SERVICE FLUID.
This article supersedes TSB 01-15-7 to update the vehicle application chart.
ISSUE
MERCON(R) Automatic Transmission Fluid is being replaced by MERCON(R) V as a service fluid.
ACTION
Beginning immediately all automatic transmission / transaxle applications requiring MERCON(R) can now be serviced using MERCON(R) V or MERCON(R) Automatic Transmission Fluid or dual usage fluids labeled MERCON(R) / MERCON(R) V. After July 1, 2007, MERCON(R) 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(R) with MERCON(R) V or MERCON(R) Automatic Transmission Fluid or dual usage fluids labeled MERCON(R) / MERCON(R) V
CAUTION AUTOMATIC TRANSMISSIONS / TRANSAXLES THAT REQUIRE MERCON® V SHOULD STILL ONLY USE MERCON(R) V OR DUAL USAGE FLUID LABELED MERCON(R) / MERCON(R) V.
CAUTION MERCON(R) 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(R) C WILL CAUSE FUNCTIONALITY CONCERNS AND INTERNAL TRANSMISSION DAMAGE.
CAUTION DO NOT USE AUTOMATIC TRANSMISSION FLUID SUPPLEMENTS, ADDITIVES, TREATMENTS OR CLEANING AGENTS.
By the way if anyone need me to look up TSB's for there trucks I will be happy and willing to do so. I dont mind. I get it all through my school so I dont mind at all.
BS. NY Mustang!!!!
You need to do a search for the other thread on this subject. Here are the plain ans simple facts, not rumors but pure fact!!
Yes mercon/Dexron III ceased being made in June of 2007, once the supply is gone it's gone, so stock up!!! Just prior to this Ford released their TSB , which says it is now all of a sudden now okay to use Mercon V in the 4R100, even though your owners manual strictly says not to. You show me where they claim a reformulation!!!!! They don't and they never will because Mercon V is still Mercon V nothing at all has changed!! I contacted the oil companies that makes the stuff and they even admitted no change has been made to the formula of Mercon V. Does it say 'new and improved Mercon V" on the bottle? Nope!!! Just says "Mercon V" THERE WAS NO REFORMULATION!!! Many of us researched this, it was all over BITOG forum and proven over and over again. Do y'all really believe everything Ford tells you???? Think this is the first time they have sold out their customers for the allmighty $$$ ? They did the same thing with the CPS issue for years, charging $169 for a $25 part!!!! C'mon, what about the Gold maintenance FREE coolant that doesn't even meet min protection requirements right out of the jug!! But they saved thousands by going to one coolant for all their vehilcles. Listen I am here trying to educate folks, you don't have to listen to me, and I will not have hard feelings. You can put lemonade in your trans for all I care. But those that care about their trucks will dig a little deeper and only use what is best for their trucks.
Good day
I can't believe I went here again!!!
Castrol Mercon V automatic transmission fluid is certified for use in ford vehicles that require Mercon or Mercon V
Certified and approved by ford for all car and trucks that require mercon or mercon v is required
Do not use this atf in applications calling for Mercon SP or Type F
That what it says and I'm sticking with it I haven't had any problems with it so I'm still going to follow the tsb and use mercon v now instead of mercon. Hey if I have any problems then I can complain to ford but i havent so..
