I should have just enough Redline C+ ATF for the AW4 but that leaves me short for servicing my NP 231. I've read many threads where they say you must use the same fluid between the transmission and transfer case. Is this actually true? I ask because I'm having a difficult time tracking down Redline C+ ATF, but there is plenty of availability of the Redline D4 ATF. Apparently they have pretty similar properties, do you think that this would be a safe substitution? Is there any communication of fluids between trans and transfer case? Thanks for your time!
