Transfer case fluid
Hello I was doing some pre winter maint. on my 96F350 w a 7.3 liter diesel and auto trans. this is a 4WD I went to check the transfer case fluid and was suprised to discover that it appears to be Automatic tranny fluid. I have changed the E4OD Transmissions fluid three time in 30,000 miles I have been using mobil one synthetic. My questions are: Does this transfer case use automatic tranny fluid instead of gear lube? The tranny is attatched directly to the transfer case do they "share" the same fluid? If so is it necessary to cahnge the fluid in the transfer case if I am changing the tranny fluid regularly? Thanks for any insight you can give.

Transfer case fluid
No worries mate... The transfer case takes ATF.. I was suprised to find it in my t/c also, & I have a 5 speed.. Thats what the specs call for & your Tranny & t/case are totally separate.. In other words one could be full & the other empty.. Enjoy your rig... Jake

it doesnt matter how much you use 4wd really, because there is always something moving in the t-case because there is an input from the transmission and an out put to the rear wheels that is constantly being used.
it holds less than 4 quarts.

Yeah, change it out whenever you change the trans fluid. It's a completly separate system and the two never mix.

If three to four quarts come out, you've got bigger troubles, cause somebody SOMEHOW (don't know how) over-filled your transfer case by one to two quarts.
Our Superduty transfer cases hold TWO U.S. quarts.

Kwik, you recently had yours out. What kind of sealing do the trans and t-case have between them?
