I have a86 cj7 with 4.2 engine and 5-speed trany. My question is what transfer case do I have and what lubricant? My Haynes manual lists three different tc's and gear oil called Jeep Lubricant No. 426xxx. What? :-? [addsig]

I think you want to use gear oil, like 75W-90, in a gear box like the D300 in CJ's.
In chain-driven transfer cases like the NP231J in YJ's, use automatic transmission fluid.[addsig]

Heres an update from Jasper engines And Transmissions web site about what fluid to use in Jeep T5 transmission.
"TO PREVENT HEAD SET BURN UP WE SUGGEST USING A MULTI-GRADE CE RATED EN
GINE OIL INSTEAD OF A.T.F. "
Just thought I'd spread the word !
