Hey everybody! I'm new to this forum and I wanted to say hello! I just purchased a 95 xj with a 3 inch rough country lift sitting on 31's. So far I love it, best 1500 I've ever spent. Now it does have some issues and I couldn't think of a better place to get help than here. So my first question is..... I am leaking transmission fluid and I'm wondering where exactly I need to add more? I looked all over my engine bay and I can't find it...... its a manual transmission, and it leaks oil and transmission fluid. I've topped off the oil but now I need help with the tranny! Thanks ya'll!

 

This question is more suited for OEM tech, unless you don't have the original transmission.

Going to need to know which engine you have. Manuals behind the 2.5L and 4.0L are slightly different.

A good writeup on how to service the AX-15, found behind 4.0Ls since about 1989, is here: http://www.jeepforum.com/forum/f12/b...change-865520/

I do not advocate using engine oil in these transmissions. Find something like Pennzoil Synchromesh to top it off, or better yet, drain whatever sludge is in there and change the whole thing. If you weren't leaking Redline MT-90 is the best oil for these. Do NOT use regular 75w90 gear oil.

Where's the transmission leaking from? You sure it's coming from there?

 

My bad..... the mods can move it! I have a 4.0 engine, ill look at that! thanks man. yes im pretty sure its out of the transmission, i also have one out of my transfer case. This jeep is a project for me. Its my first car ive paid cash for, and id like to learn how to fix most of all of it myself, thank you for your help and the link!

 

actually its my transfer case thats leaking..... im learning.

 

so im reading more, and it seems like both the transmission and transfer case use dex III is that correct? should i add that and then add a little of that syncro mesh?

 

I don't know what you use in a manual, but Not dex merc! That's for automatics!

 

No, Dex/Merc is only for the AW4 automatic transmission. The synchromesh stuff is not an additive, it is a branding of oil.

The NP231 and NP242 transfer cases will run on any ATF you can find at the parts store.

 

Just checked my service manual. Use sae 75- 90 gl5 gear oil in manual trans. (or 80-90)

 

Ok ok, sorry guys im really really slow. Any ATF for my transfer case..... since i already bought some dex-merc would that work for the transfer case?

secondly, I should add penzoil syncromesh to my transmission to top it off? i really just dont want to ruin anything.

 

As long as it is marked GL 5

 

GL5 for the transmission, not for the transfer case correct?

(again im sorry im so slow, this is a new area of hobby for me)

 

Right. I'm sure if it's marked GL 5 its ok.
Maybe others are too.
Don't know about Synchromesh.

 

awesome, thanks bro! im sure ill get this thing figured out. I will make sure its GL5, on the site it says its GLS, im sure its the same. and ill add the dex merc ATF to my transfer case.

 

Do NOT put GL-5 in your AX-15! It is corrosive to brass and will destroy your synchronizers.

Feel free to top it off with the Synchromesh. It's designed for your gearbox.

Dex/Merc is a very common ATF and will work fine in your transfer case.

 

OK that s plain enough for me! I will do exactly that! Thank you for the help
