atf transfer case

2001 f250 stock automatic transmission


going to put Mobil 1 Synthetic ATF a multi-vehicle formula or Schaeffer Manufacturing Co. 0204SAT-006S All-Trans Supreme in stock transmission......good idea or bad idea?


On the transfer case what should I use......I have read about 5 thousand postings on several forums(I may have missed the one I should have read) some of them are very old


What is the current say so on using ATF in transfer case( IE one of the above) I think everyone is saying now use XL-12 from ford? Did something change in mobil 1 synthetic around the time xl 12 came out? I have been reading about people using mobil 1 syn in their transfer case for a decade now with evidently no problems so is it chemically different now?

I always use the cheap Walmart brand ATF in my transfer cases, never had an issue. You can use the more expensive stuff if you want to, but it is a waste of money in my opinion, transfer cases aren't that picky.

Im remembering reading right on the bottle of mobil 1 ATF"not to be used in transfer cases"

my transfer case requires a mercon V compatible fluid and Mobil 1 is not mercon V compatible.

The motorcraft transfer case fluid is not that expensive. Plus, you only need 2 quarts.

You can use Mercon, Mercon V, atf +4, or the expensive transfer case fluid, it really makes no difference the main thing is that you change it when you should.

YES on the mobil 1 synth in your transmission. Leave the Schaeffer snake oil out. Won't do a thing, complete waste of money.

Get the Ford stuff for the transfer case. You only need 2 qrts. do NOT USE MERCON V IN THE TRANSFER CASE.
