    No, use XL-12 or Dex/Merc.

    No, Mercon-V will destroy the transfer case.

    Use one of the following:

    Ditto. The Mercon I(Mercon/Dexron III) was replaced by Mercon V, but later they decided the Mercon V was bad for transfer cases. So they created the XL-12 stuff just for TC's, which is rumored to be virtually the same as Mercon I.

    So keep your Mercon V for the trans or PS only. Buy the easy to find Dexron III, which all still mention Mercon on the labels, for the transfer case. The Mercon V is too slick for the TC, it creates more heat and burns them up.

    As covered extensively on other thread(s), Ford has "obsoleted" the XL-12 "Transfer Case Fluid" (per Varsity Ford in Ann Arbor, MI) and now specifies Mercon LV for our transfer cases. Just don't put it in the transmission . . . .

    It is interesting. Again the manufacturers cross applications with the same fluids, and expect no problems with customers figuring out what they need. OEM doesn't mind mixing fluid usage among systems like power steering and transmission. But customers shouldn't be put in a tough position to keep up with the changes.

    Fluids change regularly these days, confusion in books and manuals, and service writers, it causes problems. I prefer to use one fluid for the intended(what is on the container) usage, if possible. It is possible to find and use only PS fluid for the PS system, thus I do not use ATF for PS.

    Transfer cases have become the same way now given the fluid changes over the last 15 years or so. It's time to stop using any ATF in a TC, and find specific transfer case fluid, to use in just TC's. Hopefully the Valvoline TC fluid will be a proper fluid for all TC's for a long time, and remain feasible. $5 a quart isn't bad for a TC fluid that you only need 2-3 quarts of at a time, or $8+ each if you have to buy single bottles.

    Yes, the top hole is the fill level, and the front drive shaft and axles etc, all turn at all times.
