Mercron Syn vs. Mercron V
Hi:
I really confused about which will be my best option to change the oil of my 4R100 trans.
I've been reading about avoid use of Mercron V in my 99 5.4L SOHC Navigator, but my questions are:
1.- Can i use Mobil 1 Synthetic ATF?
Mobil 1 Synthetic ATF
2.-Is the synthetic ATF mercron V? or not necesarly
3.- Which will be the nest ATF for my tranny?
Thanks for any advice, i'm really confuse.

Mercon V is now what is reccomended for the 4R100. the formula has changed from when Mercon V first came out.
but any fluid that is rated for Mercon or Mercon V is alright to use in your transmission.

I´ve reading nightmares stories about the use of Mercron V in the 4R100.
So, Is the new "edition" of Mercron V safe for 4R100? or I use ATF Synt for go to the safe way?
Thanks for the advices.

ANY FLUID THAT IS EITHER MERCON OR MERCON V IS SAFE FOR USE IN YOUR TRANSMISSION.
Ford changed MERCON V from it's original specs to make it compatible with the 4R100 and all other transmissions that used to use MERCON.
I like Mobil 1 synthetic ATF for the 4R100.

You also cannot buy Mercon/DexronIII fluid any longer its not sold. Ford and GM stopped licenses a year ago. Most companies still sell this new "multi vehicle ATF" which is supposed to be the same but with no quality control from GM or Ford who knows if the fluid is a quality fluid.

I just got a 2004 Ford F150 4.6L with automatic tranny. I read the owners manual and it said to ONLY use Mercon V for the transmission fluid and that it COULD NOT be mixed with regular Mercon.
It said to use regular Mercon for power steering fluid.
I need to change out my transmission fluid and filter...any recommendations on fluid that I can pick up locally?

So this must have been a change after 2004 when my owners manual came out?
Anyone know exactly what transmission I have? The owners manual seems almost worthless aside from a few thing in my opinion.

All 4.6L F150s have the 4R70W trans, which required MERCON V before this change.

For those that use the Dealer for service, he keeps up with all the changes, for those of us
who do our own service, it's up to us to keep up to date on all the changes & as Mark has said, Mercon-V tranny fluid has been reformulated, so that it can also be used in previous Mercon call outs, like transmissions & power steering systems.
Scroll up to the top of the page & click on "Full Text" TSB's & enter your year, there you'll find a whole bunch of full text TSB's on your F-150, among them the change in tranny fluid specs & a whole bunch of other interesting things, some pertaining to other models as well.

Okay. So I read the service bulletin in "full text" at the top of this page. Very interesting, it has all the recalls and good stuff from my model year. I still have one question though. The page said that Regular Mercon is no longer being made so now Dual purpose Mercon OR Mercon V can be used as power steering fluid.
I have a quart of Valvoline Dexron III/Mercon Automatic Transmission Fluid. This fluid should be suitable for adding power steering fluid to my truck right?
It still sounds like Mercon V is the only fluid that should be used for the transmission itself though. If anyone can tell me if what I have is safe for the power steering, that would be great.
