Transfer case oil
« on: September 24, 2017, 06:10:19 PM »
I want to change out my Transfer case oil and I have some extra Allison Synthetic Transmission fluid from changing out the fluid in my pickup, the manual says to use ATF4 fluid..... Does anyone happen to know if the Allison fluid meets ATF4 specs or is better than that ?  I would rather use up what I have on hand.

Thanks

I'm pretty sure theres no clutches in the transfer case, only gears and a chain so I think Allison Transynd would of worked since it's a full synthetic fluid, BUT I found 3 quarts of NAPA ATF+4 on the garage shelf that I had left over from changing the tranny fluid in the 05 LJ last year, so I used that, a little over 2 quarts went in.

Changed the rear ends fluids too with some Mobil Synthetic 75-90 I had, just 2 quarts went into each of those. Glad the pumpkins have a drain plug so I didn't have to remove the Jeep aluminum covers on there.

Speaking of the Jeep aluminum covers, they have a weird design, the fill plug is way up high almost at the top of the cover, not in the usual half way point that you would fill up too and let it dribble out.

Sort of looks like this...notice how high up the fill plug is...


So all the fluids are changed and ready for Rocktoberfest.

And the new skid plates are on too.

that's to allow for rotating the pumpkin to correct pinion angle in lifted Jeeps with double cardan shafts

 Isn't that small allen screw, just to the right of the Jeep emblem on the cover, a weep hole?   You take that out and fill till it comes out that hole, then button it all up.

That's exactly what I ended up doing.

I might have to steal that idea and put a weep hole in my Solid cover!  Beats using a zip tie as a dipstick!

You can put anything in the tcase :eek: Some people put in a lightweight oil. I was once told that the only reason ATF was specified, was for Jeeps that never get put in 4wd. So they won't gum up.
Well, not anything  :mad02:
