Fluid change recommendations

[that_tj_tina]

Hey y'all!

This is my first post on this forum! I bought a 2000 Wrangler Sahara with a 4.0 manual transmission and 63k miles on it a few weeks ago and I'm looking to replace all the fluids but I'm having trouble finding which kinds to get. I did some research but it's really overwhelming for me right now. Any help would be greatly appreciated!

Here's what I have so far:

Coolant - Doing a coolant flush and putting in Valvoline Zerex G-05

Already did the oil

Front and rear differential
I have a Trac-Lok in the rear diff. What 80W-90 gear oil would be best? I know I need something with a limited slip additive because of the rear diff.

Transfer case
I'm pretty sure I have the NV3550.

Manual transmission fluid

Power steering fluid
Any suggestions on power steering fluid? I've read some posts about using ATF+4 for power steering for Chrysler cars made after 98'.

Brake fluid

Clutch fluid
Should I just use the same fluid that use for the brake fluid?

Any suggestions on what I've provided would be amazing!

Just to clarify, you have the NP231 transfer case, which takes any old ATF+4. Your transmission is the NV3550, for which Redline MTL is most recommended. I would not use that Pennzoil synchromesh.

As far as I know, Jeep used power steering fluid until 2002 before it switched to ATF+4, so I would use the former unless you completely flush. I think there is some debate about how well they mix.

Use any name-brand gear oil for the rear diff as long as long as it has friction modifier included, which they virtually all do. Just know that at 63k, your limited slip clutches are close to worn out if not gone entirely, so you essentially have an open diff.

Any old DOT3 brake fluid.

You shouldn't have to replace the clutch fluid, but DOT3 brakes fluid is fine. Personally I'd just change the master/slave cylinder if you are having any problems.

Use the Redline MTL for the transmission, it's the best option as far as I am concerned for your NV3550, and most will agree.

Your 2000 uses power steering fluid not ATF in the steering system. X2 to the recommendations for MTL in your transmission, not Pennzoil Synchromesh!

Most GL-5 gear lubes contain sufficient amounts of the friction modifier for you Tracloc. You can confirm if it does if on the back label it says something like 'Compatible with limited slip differentials' .

And another vote for the Redline in the trans. Well worth the extra coin!

Aren't there other options besides atf for the transfer case. I use atf4 in my 241. I was under the impression that 30 weight motor oil could be used as a substitute.

Also, atf and power steering fluid shouldn't be mixed, but couldn't the steering pump and box be flushed with atf to replace the power steering fluid.

Chain drive transfer cases like come in Wranglers use ATF, gear driven transfer cases use gear lubes... or motor oil in a pinch. 2002 and older Saginaw steering systems use power steering fluid, 2003 and newer Mercedes steering boxes use ATF.

I was under the impression that atf and power steering fluid, while not compatible, are interchangeable in steering systems and that Chrysler engineers respecified atf4 for steering for simplification as well as to increase demand for atf4 when it was first put on the market, am I wrong about that?

Yes.
