Np 231j transfer case question.
Alright this weekend the T-case and both differentials are getting new fluid. Question is what are you guys running in your T-case?. I'm sure bout what I'm gonna use in the front and rear, but I'm not clear on what the transfer case calls for??? Any suggestions or what the OEM calls for. Thanks:confused:

Calls for ATF in there. I once bought a rebuilt 231 and the re-builder insisted I use Delo 30W or Delo 15W-40 motor oil in his rebuilt case. That was required for his warranty.
I've now run it in 231's for years and it works great, runs quiet and does't tend to leak as much.

ATF is what the factory calls for

I used the extra atf that I had left over from the transmission fluid and filter change. That's how I planned so I bought extra Dexron III.
Btw, the views get exaggerated by other sources like google. Not the best way to explain it but the best I got... :D
