Simple T-case question - fluid change

Cacher123 · **Posted:** Sat Nov 10, 2007 8:18 pm

Ok, before everyone says to "search", I did and got like 1800 plus hits!
Gonna change out my Transfer Case fluid - just my Transfer Case.

All I'd like to know is:

1. How much fluid just my Transfer Case holds (not my transmission or my front and/or rear differentials)?

2. What kind/weight of fluid?

3. Does it need any additional additives?

4. Do I need to know anything tricky about this before I put a wrench to it to prevent the inevitable loud exclamation of "Oh crap!!!" :shock:

which usually occurs when I work on something simple?

I'm gonna try to tackle this one myself this tues.

it takes the same fluid as your transmission and takes between 1.4-1.6 litres depends if you have the nv231 or the nv242.

ATF+4, no special additives to it

There should be one drain plug and one fiill plug.

here is good info on how much of what kind of fluid our vehicle takes:

Hope this helps!

1.I believe mine took right at 3 quarts but its kinda hard to remember.

2.ATF+4 Fluid(walmart has mopar for cheap-$5 quart)

3. No

4. It can be kinda hard to get oil back into the tcase. I picked up a lower unit pump(made for boat engines) at walmart for $7 or so. Worked great!

I just did mine last week and it took just under 2 quarts. I used the AMS OIl ATF+4. No need for additives like previously said and the little pump Jeepster showed is pretty much what I got. It makes it so much easier when fillling your TC and Diffs back up with fluid. I would highly recommend you get one if you don't already.

1. 2 qts will fill it w/ a little left over.
2. ATF+4 type transmission fluid. Of course I suggest a full synthetic like Amsoil. :wink:

3. No additives needed
4. make sure you have the right size tool for the job so it doesn't slip and bust your knuckles. you can imagine why I say this or look at my scarred knuckles. A pump is a huge help when filling though I have used a funnel w/ hose adapted to it and careful pouring.

Good luck!

Also the general wisdom is to remove the fill plug first. If you pull the drain plug and later find the fill plug is seized in place, or strip it, it's a headache.

That's exactly the kind of thing that would happen to me! :shock:

I know for a '02 with Command-Trac(231) the fill and drain plugs are 3/8" allen wrench/socket.

Ahh, I cant remember what it took but I know it was a big Allen socket.

Why not just loosen but not remove the fill plug, then remove the drain plug. This way, the fluid doesn't pour out fast immediately. Then go back and remove the fill plug the rest of the way.

Kinda like, when you have a can of HiC and you open a hole with the can opener and try to pour it out. It comes out real slow, but once you open a hole on the opposite side of the can lid, it pours fast.

Come on now, you all had to have experienced a can of Hi C as a kid....... :lol:

Well maybe showing my age......... :lol:

Oh man I remember helping my dad do oil changes and opening those with the ol' church-key opener. Wow, another trip down memory lane...

ATF+4? NOT 80/90?

Nope. T-case uses ATF+4. The stinky stuff. I found this hose with an on/off valve that fits right onto an Amsoil bottle.

Gotcha. Thanks.
