NP231 lubricant
I was wondering anybody can tell me what kind of fluid used in NP231
transfer case.
The dealer said ATF+4, Haynes and car parts shop said using Dexon3,Mercon
Auto transmission fluid.
I already changed the fluid using Dexon3,the noise from t-case is still
there. Should I use ATF+3 or 4?
It's a 92 cherokee Laredo, 4L Auto.
thanks

1993 NP231 states Dexron II, Mercon, Mopar ATF Plus (type 7176)
1.6Qts (till it dribbles out the top fill plug)
Dexron was dropped from the Chryseler/Jeep compatibilty list back in 1997.
Modern versions of those are acceptable.

ATF+4 is a pure synthetic for vehicles newer than 1999 and probably not
correct for your application. Jeeps says it's required for the latest
NP diff, but your diff was made way before ATF+4 existed.
Your noise may not be the fluid, it may be the link adjustment or
a stretching chain. However, it's cheap enough to try it again with
a ATF+3 fluid.
That's what I use, but then again I have the NP249

Interesting. Guess I'll go with +4 next time I drain the xfr case.
Although I don't like the bit it says about not being able to tell
water contamination by color anymore.
