Ford used a Mercon ATF for these and now specs some kind of Ford XL-12 Transfer Case Fluid (whatever that is). I'm trying to get my winter prep done around here in lovely Chicago area, and realized I haven't changed the transfer case fluid in like 100k.

Anyone know if this been hashed out here, best Mercon ATF for Ford transfer cases?

I used Maxlife when I changed my transfer case. I don't know that any brand is going to be better than another for a transfer case, any Mercon fluid should work just fine.

I don't know what is best, but I used Valvoline Transfer Case fluid. I didn't even know that it existed until I was shopping online for XL-12 and gear oils. I ended up buying both the gear oil and transfer case fluid from Advance, and with the 25% discount that was offered at the time, it was all pretty fair priced.

I will be getting a VOA for the Valvoline next week and post it when I get the results. It says for use in Ford XL-12 and GM Auto Trak II applications.
