Ax-15 trans oil

I personally use MT-90 in my 1999 cherokee Ax-15 trans. No issues and nice shifting all gears after 30 second warm up. Syncros will appreciate it also since they are brass. (hint)

Don't bulk about the price. If you own a ferrari you pay ferrari prices.

It's not an issue of paying for good fluid, I have an issue with the price of RP products when there UOA's and VOA's don't look any better than fluids half the price.

My '99 Sport with 138k miles on it now has synthetic 10w-30. I wouldn't be surprised if what was drained was original! It shifts much smoother, and is quieter now. Everything else has what's listed above.

What went wrong?
My Cherokee is a 1994 with 250k miles on it.
All I been using is Ams-oil 75-90 GL5 SD fluids.
The jeep runs very quiet and smooth.
Are you sure the manufacture changed the book?
I called Jeep and they said go by the original owners Manuel for my jeep.

No jeep tech I know agrees it better to change to GL 3 or 4 for my cherokee.
All I can say if you guys are correct........... my jeep's drive train should of failed yrs ago imo.
I will pass on this, and using motor oil in a transmition.
Peace.

Nothing went wrong. All GL-5 oils are designed to resist high heat but all
do not do it the same way. Those with high sulfur content end up being
dangerous for yellow metal. Some people have bad experiences with those,
and Tim's post #2 in this thread is trying to help Jeepers avoid that problem.

The Amsoil GL-5 you are fortunate to have chosen is Synthetic, safe for
yellow metals, and GL-4 compatible.

But, if you still think any GL-5 is just fine, why not put a high sulfur one in
your favorite Jeep's AX-15 and check back here in a year or so ?

I agree with your answer! On syn lubes having less sulfur.

I have had some time off this week I made a few phone calls and you are correct about using syn lubes. I guess we should look in a tad further on the Chrysler so called "recall" on this situation. I have not found any legit one so far, but thanks for your post.
btw,,,,,,,I called Chrysler Jeep on the so called "service notice" on my jeep and they had 0 on it as far as changes.

Bottom line is go with what the manufacture states in the owners manuel.

Stated where?
Here ? Redline publishing? etc.....?
Look I called the Chrysler Corp and they told me to go by my MANUAL.
I would think after 250 k miles I would of been proven incorrect following the manual vs a bunch of shade tree publication that says Chrysler printed faulty Manuel's You think?

I just want to know why its so great/nessesary to use other lesser lubes vs the manufacture fluids recommended ?
If you like living on the edge ok I understand. Go for it!
But cheap jeep drivers like me want to use what keeps my XJ on the road as cheap as possible.

Hey if castor oil/ peanut butter is better for this tranny i say Cool,
But I have told you guys in the past " when I shift this jeep its like smooth honey!" I guess I will never know why GL 5 does so good in my Jeep!



Peace

Page 191 of my 1998 Owners Manual says to use a GL-3 oil in the manual transmission.
Section 1 of API document 1560 8th edition dated April 2013 lists several designations, including GL-3, that are no longer in use. The doc doesn't give clear direction that a GL-5 is a direct substitute. You have to interpret the application basedd on gear type. The wording seems to be really geared to axles - which do not contain synchronizers.
I have not been able to find a GL-3 spec oil to buy. Therefore, thus far, I'm leaving my existing GL-3 oil in the trans.
I'm tempted by the Penzoil Synchromesh description that says it is compatible for use with yellow metals (brass, bronze, etc) which would cover synchronizers....but I haven't pulled the trigger yet because I can't find a cross reference from the Chrysler spec they reference back to the AX-15 boxes (which were made by AisinWarner, not New Process Gear like most of the other Chrysler manual transmissions).
Just my 2 cents...

As for errors made by Chrysler in the Jeep owner's manual, yes, they exist. (see pictures)

In my 97 Cherokee Owner's Manual, it says on page 164 to fill a Jeep manual transmission
with SAE 75W-90 GL-5 lubricant. I wrote the correction by hand.

However, you turn to page 191 and the recommended lubricant is SAE 75W-90 (API GL-3).

In the third picture, the Factory Service Manual for 1997 says fill either the AX-5 or the AX-15
with 75W-90 API Grade GL-3.

I looked here as well for those corrections made on your book.
All my book states is GL 5."all pages"

I guess you better use gl 3. But I would question why your book has 2 different grades.

My Manual is consistant on the GL 5 grade. I said earlier, even the Jeep rep at the Chrysler said GL 5 is for my Jeep Cherokee.
Its weird man, and confusing that the 1997 manual guys wrote in a change !
peace.

GL-5 does fine in 94beachxj's Jeep probably because he has a Peugeot
BA-10 manual transmission, NOT an Aisin AX-5 or AX-15. See his thread
on 6-29-2014: http://www.jeepforum.com/forum/f22/m...parts-2528802/

The discussions on this thread pertain to the Aisin AX-15 transmission (see
the thread title) and the harm that some GL-5 oils do to the brass synchros.
The experience that 94beachxj had with his 94 that he likes to go on
and on about is simply off-topic.

Read it

"Chrysler now recommends that 10w-30 motor oil be used in Cherokee manual transmissions"

I did! So I responded to this notion.


Regardless what type of tranny I have ,,,,,, the point I made was to use what your owners manual states.

You think motor oils help transmitions vs the reccomended fluids?

And thats Off topic?????????????????????????

I saw this thread and wanted to try to stop a cherokee owner from making a BAD mistake!
Shoot me dude !
You really think reg motor oil will solve the problem?

Come on man we all want the best for our Jeeps.
Chill Mr off topic!

btw I see many post in here like this one that suggest using motor oil or GL 3 or 4 oils in MY JEEP!
If wanting to use my experiences to stop and help another jeeper is "off topic" well I guess I do not belong here.
I mean if its ok to tell a fellow cherokee owner to NOT follow manufactures advise.......then yes I am a fool and should be ignored.
peace.
