Wrangler TJ Fluid Capacities & Fluid Recommendations

I have a NV3550 5 speed manual is there any transmission fluid that you can pick up at your local Napa or do you have to go to the dealer to buy there fluids

For the NV3550 you can use 2.1 quarts of Mopar fluid (part #04874464AA) or Synchromax (meets Mopar MS-9224 specs)

The only other two products I found (other than the above two I linked to) that met MS-9224 are Pennzoil and Quaker State Synchromesh.

Stick with one of those. You may be able to find it at the auto part store, but whatever it is, it needs to meet Mopar MS-9224 specs.
 
Is there a stamping on the transfer case for which model I have for a 98 Sport, manual transmission

Transfer Case
231 - 1.1 quarts ATF+3 or ATF+4
241 - 2.1 quarts ATF+4
 
How important is the 0.1 quart of oil in the NV3550? I want to pour new fluid in, but I'm having some heartburn over paying 20 bucks for a quart of oil I only need a tenth.of a quart from.
 
Here is my question. What kind of oil does a 2002 Wrangler Sport take? This is my first Jeep and I am not sure and don't want to mess it up.

You can run 5W-30 or 10W-30, any brand of oil.

Synthetic isn’t necessary at all unless you live in a really cold climate region.

Looking to do a overhaul on fluids in my 02 Sahara. Dana 30 (open) Dana 44 (LS) 32RH and the coolant. Diff and coolant I’ve done before on my old 06 TJ. My question is what’s the best way to do a flush on the 32RH 3 speed auto transmission on the jeep? I will be buying a new filter and gaskets for it as well.

How to flush the automatic transmission on your Jeep Wrangler TJ

That's a how-to article on how to flush the transmission on a 32RH.
 
Here's a list of the different fluid capacities for various Wrangler TJ models.

Engine

2.5L 4 cyl - 4 quarts
2.4L 4 cyl - 5 quarts
4.0L 6 cyl - 6 quarts


Transmission
30RH 3 speed auto - ATF+4 (ATF+3 originally recommended; ATF+4 is replacement). See post #2 below for fluid amount.
32RH 3 speed auto- Approximately 4 quarts ATF+4 (ATF+3 originally recommended; ATF+4 is replacement) when drained via dropping the pan / Approximately 8 quarts dry fill. See post #2 below for FSM procedure.
42RLE 4 speed auto- Approximately 4 quarts ATF+4 when drained via dropping the pan / Approximately 8.8 quarts dry fill
AX-5 5 speed manual - 3.3 quarts 75W-90 GL3, 75W-90 GL4, or 10W30 (NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals)
AX-15 5 speed manual - 3.32 quarts 75W-90 GL3, 75W-90 GL4, or 10W30 (NOT GL5 or GL5 compatible as incorrectly stated in some of the manuals)
NV3550 5 speed manual - 2.1 quarts Mopar fluid part #04874464AA or Synchromax (meets Mopar MS-9224 specs)
NV1500 5 speed manual - 2.4 quarts Mopar part #04874464AA or Synchromax (meets Mopar MS-9224 specs)
NSG370 6 speed manual - 1.58 quarts Mopar part #04874464AA or Synchromax (meets Mopar MS-9224 specs)


Transfer Case
231 - 1.1 quarts ATF+3 or ATF+4
241 - 2.1 quarts ATF+4


Axles
Dana 30 - 1.25 quarts 80W-90 or 75W-140
Dana 35 - 1.75 quarts 80W-90 or 75W-140 *
Dana 44 - 2 quarts 80W-90 or 75W-140 *
Rubicon Dana 44 (FRONT) - 1.375 quarts 75W-140 synthetic
Rubicon Dana 44 (REAR) - 2 quarts 75W-140 synthetic **

*4 oz of friction modifier is required with Trac-Lok limited slip differential.
**Friction modifier is NOT required with Tru-Lok locker/limited slip differential (factory Rubicon locker).



Cooling System
2.5L - 9 quarts
2.4L - 10.1 quarts
4.0L - 10.5 quarts

I always recommend running OE Mopar coolant.


I'm going to assume the amounts for the Dana 44 are for the stock covers. I recently purchased G2 covers (
G2 Dana 44 Aluminum Cover - 40-2033AL)
for my 200 Jeep TJ Rubicon that has Dana 44s front and rear. Aside from being aluminum they are larger to hold more fluid as I understand and with the protection of the new covers, the added fluid keeps the gears cooler. I installed these yesterday and put about 2.5 quarts into each and the level hadn't reached the fill plug (normally when it drips out you're full) but I think 2.5 is plenty. Thoughts on whether I should add more until I reach the level of the fill or leave it at 2.5.

2.5 is plenty.
 
I see conflicting reports about the NP231 transfer case fluids - On extreme terrain, it shows a different transfer case fill level for the Manual Transmission vs. the Auto (Note: it calls out the transmissions separately, as well as the transfer case). That said, I thought the NP231 was common between the 2. It says for the manual transfer case, it requires 1.5 quarts instead of the 1.1 quarts.

Now, I'd err on the side that the information in the first post is more correct than extreme terrain's, but is there really a difference between the 2 transfer cases?

Taken directly from the factory service manual:

That states that the NV231 transfer case takes 1 liter of fluid on BOTH auto and manuals.

As mentioned in the original post of this thread, it requires 1.1 quart.

1 liter equals 1.05669 quarts.

The extra fluid won't hurt it at all, hence rounding it up to 1.1 quart.

I don't know why Extreme Terrain has incorrect info, but I do know that I wouldn't rely on them as a reputable source of information.

I agree - I've seen enough wrong info on Quadratec and other sources to know better, although similar to the GL-5 statement on the transmissions, the FSM isn't always right either. Just figured I'd double check to make sure I wasn't missing something (especially if I ever wanted to get a replacement transfer case).

Makes perfect sense! In the scenario of the transfer case, having a bit more fluid in there won't hurt anything anyways.

It's one thing to put a little more fluid in than let's say putting in an entire quart more!
