Yeah I'm sure you can use whatever you want
And I'm sure people have had success with that.

Hell, I saw some guy on YouTube putting gear oil in his transmission.

Whatever.

I am just trying to get as close as I can to what mother Ford recommends.

It makes me sleep better at night I reckon.

Did I ever tell you about my great great grandfather that smoked three packs of cigarettes a day I lived to be 100?

Yeah
I didn't think so.

Anyway thanks for all the help fellas.

It's appreciated

All good bud. Your ride! Your rules...

But you asked our help sooooooo?

Save your money on the full synthetic transfer case fluid.

Every single obs and supper duty that has been in my family from 95 on has had mercon 5 in the trans and tcase.... we probably have 1 million miles, if not more, combined ourselves. Thats all i had in whitey from the first year i owned her till the day i sold her. And im guessing Ryan didnt change much about her. Lol

my 12 had and now my 15 have LE 1150 trans fluid in the trans and t case and technically, its not even ford spec..

Combined, thats around 265k miles of personal experience plus we have probably millions of miles of guys running the same exact thing that is "not the correct stuff" without failure. So just because it says it dont use it doesn't mean it wont work..

Now we are switching everyone over to driven fluids.

What do you think about 7500 vs 1150?
