In an earlier post I mentiend that my transfer case started leaking shortly after filling it with the new blue Auto Trac II synthetic fluid.
Without entering speculation about systetic vs. nonsynthetic I decided that I will dump the new fluid and go back to conventional.
I have NVG-246, and I read that purportedly only NVG-246 requires Auto Trac fluid. NVG-243 is OK with ATF.
That makes me wonder what is the design difference between that mandates any special fluid in NVG-246?
Or will NVG-246 do just fine with ATF?
