    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.

    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.

    Thank you. Like I said, I don't want to mess up the anything on this. I might have more questions since I am a novice.

    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.

    That's a how-to article on how to flush the transmission on a 32RH.

    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:

    Screen Shot 2018-05-14 at 11.54.43 AM.png

    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!
