Has anyone ran 5w30 Mobil 1 in there transfer case instead of trans fluid I run it in my Duramax transfer case no prob.
Yep my 09 caliber with 343K km on it used Mopar ATf+4/5 and it's been changed only once it that time.I just get the Motorcraft specific "Transfer Case Fluid" from the dealer... XL-12 I think it is.. It's only 2 qts so no big deal on cost compared to the cost of the TC.. I've changed the fluid in it at around 60k miles, so might have to start thinking about another change here soon. (just about to roll over 100k)
My old 86 Mustang GT with the 5.0 and 5 speed used ATF in the manual trans.. So there you go..
Good luck! Mitch
