Hi,
I have a 2001 v10 4x4 and am going to change the transfer case fluid tomorrow, Is it ok if i use Mercon V? I did a search on this forum and got mixed results. From my understanding originally Ford said not to use mercon v in the transfer case but then discontinued mercon and told everyone that mercon v should be used? I would just go out and buy some full synthetic ATF but i have 2 quarts of mercon v already sitting in the garage and would like to save myself a fer dollars if i can!

 

I had a 2006 Ranger and replaced all fluids with Royal Purple.
Great results!
or...
buy some more "Mercury Mayhem" and have at it!
I honestly don't think that it matters.

 

Thanks for the reply. Thats what im thinking it cant matter that much,o well only one why to find out lol

 

The original transfer case fluid was Mercon, now it is Motorcraft Transfer Case Fluid XL-12, since they discontinued Mercon. Most people use Mercon V since it replaced Mercon
