2015 F250 4x4 transfer case

[Donald]

Ford lists "Motorcraft Transfer Case Fluid" for the transfer case, not ATF or gear oil. The Amsoil website lists the same ATF as their transmission takes.

Its only 2 QT so I can buy it at the dealer. But I would prefer to run an Amsoil synthetic fluid if possible.

Anyone know about Motorcraft Transfer Case Fluid?

 

[Donald]

Is the Motorcraft xfer case fluid synthetic?

Ford XL-12 TC Fluid

I think you can use almost any fluid in there, but avoid Mercon 5 if you have a 4Auto TC with clutches. I used redline D4.

I think Ford has discontinued the XL-12 in the last couple of years and now recommends Mercon LV.

Motorcraft transfer case fluid is basically the old Dex/Merc that was used in part time transfer cases for decades.

The Transfer Case Fluid is pretty much the old Dex3/Merc. It has been recently been made obsolete and replaced by Mercon LV.

Is Ford saying all Mercon and XL-12 cases are backspeced to LV? I think I'll continue using cheap Dex/Merc instead of Mercon LV.

 

[bdcardinal]

They are saying XL-12 Transfer Case Fluid has been replaced by Mercon LV. Read into it what you will, just repeating what the mother ship tells us.

"For use in all transfer cases"

Should be fine in my NP205.

If you can find Kendall VersaTrans LV, it would be a great alternative. My indy actually used it in place of Mercon SP & LV in my Ford work van transmissions, and they worked well on it.
