You want brass synchro friendly fluid. I use MT90 but won’t be home for a few more days to take a picture of what I use

Definitely get GL4, I’ve used Redline MT90 in mine for the past 40k miles. Apparently there’s a Royal Purple gear oil that people really like in these R151’s too.

I have a 92 LJ78 with auto trans.
Does the transfer case have brass components in it like the manuel gear box does?
If not should I still use GL4 or is GL3 preferred?
Also, what weight or weight range is good for protection and for fuel economy (less drag)?
