did you read the beginning?

" I am basing most of my thread of my experiences with my 96 4.0 XJ. You always need to do your research into your own year models to get the right parts or tools."

lol I do apologize if it is not as thorough as your recent oil thread...

I did enjoy that read by the way

 

Nope I guess not lol.

Since I was a **** I'll pitch in!

AX-15: Requires an API GL-3 or GL-4 gear lube. Unfortunately no longer easy to find on the market as most current transmissions use other oils. A Chrysler FSM erroneously printed that GL-5 is an acceptable substitute. It is not: GL-5 is specifically designed for hypoid gears and includes extreme pressure additives that are corrosive to brass synchronizer rings in the AX-15. Unlike other standards, gear oil specifications are separate and not backwards-compatible. Additionally, as soon as warranty support ended on the AX-15 Chrysler stopped carrying any correct oil and superseded the part number with 10w30 (much like they stopped carrying Dex III/Merc for the AW4). The best oil for this transmission is a purpose-made lube like Pennzoil Synchromesh, Castrol Synchromesh, or on the fancy side Redline MT-90 and Royal Purple Synchromax. GL-5 gear oils that do not have sulphurous additives can also be used. These are typically synthetic and labelled "yellow metal safe"

Peugot BA5/10: same as AX-15

New Venture NV3550: Similar to the AX-15 but I don't think there are brass synchronizers. Same 5-speed used in TJs.

Chryser TF904/30RH/32RH: ATF+3 or ATF+4. Do not fill with Dexron fluids! D/M has friction modifiers that will cause clutch chatter in Chrysler transmissions and will lead to failure.

 

In addition to servicing/bleeding the brake fluid, I recommend inspecting the lines from the master cylinder/ABS pump out to the brake assemblies. Many XJs have been taken through deep water and mud or driven over salted winter roads. Many things will corrode and need attention. However, I've learned the lesson about waiting to change a rusted hard line. You don't need to go fast but you do need to stop. Use the search function/YouTube to find how-to help on bending and flaring brake lines. It is very simple and with practice/attention to detail you can replace all the hard lines yourself...SAVING A TON IN LABOR COSTS!!!

 

great suggestion.. ive taken my front wheels off my 96 to inspect some things.. but I havent really dug into the brakes yet.. thats on the list of "to-do's"

 

I work for NAPA and this is correct. The NAPA Gold filter 1085 is the same as Wix 51085. NAPA also makes a standard filter 31085 that is made by Affina (Wix) that has nearly the same amount of paper media but has different types of adhesives and chemically treated media. It is still a very good filter. The ProSelect 21085 is used by most shops. It is the cheapest of the Affina filters and has less paper media in it than the others. NAPA Platinum filter 41085 is a newer filter offered by Affina group that is engineered for synthetic oil. It is rated for 7500-10000 mile use, depending on conditions.

The author of this post notes that the 1515 filter can also be used. This is the standard Ford 1 quart filter, although it is also used in a number of Dodge engines. It has a different micron rating than the 1085. I recommend using the 1085 over this filter despite the 1515 being a longer, larger filter.

 

great napa info sir..

BUT... per wix's website.. the 51085 and the 51515 share the same micron rating at 21

the 51515 is identical except for a slightly lower burst pressure..

 

I just tried the Wix 51452 filter this oil change. Just a heavy duty version of the 51515

Someone actually read that thread!

 

ATF Fluid Change
I have been researching the proper ATF to use when doing an AW4 automatic transmission fluid change and ran across this old post. ATF fluid and recommendations have changed significantly since the XJ was manufactured and Dexron III was used as factory fill. The following from the original post should not be considered as factual: "The AW4 automatic transmission takes dexronIII/mercon transmission fluid. IT DOES NOT TAKE ATF +4"

My research shows that there are lots of opinions in many places that say ATF+4 can or cannot be used. However Chrysler published service bulletin 21-014-07 in October 2007 that specifically states that automatic transmission fluid type ATF+4, type MS9602, is recommended for Chrysler transmissions including 1989 – 2001 Cherokee. It is also approved for use in Wrangler, Comanche and Grand Cherokee. The service bulletin specifically states “AW-4 (Asian Warner) transmissions are now included in this Service Bulletin. ATF+4® is recommended for AW-4 (Asian Warner) transmissions”.

From SAE technical paper 982674 on Chrysler ATF+4 development: “The development process for the new ATF involved a significant level of bench testing and eventually vehicle tests to evaluate the durability and shift quality of the ATF. The bench tests included those that pertain to oxidation and shear stability, anti-wear, frictional properties and torque converter shudder. Vehicle tests were primarily extended durability in both internal vehicle fleets and at external taxi sites. The mileage accumulated in this phase of the development program exceeded two million miles, all with no fluid drains out to 100,000 miles.”

Dexron III is a lower performing ATF fluid that turned out not to be the best for anti-wear, thermal breakdown and long life. It is possible that changing to any new transmission fluid can dislodge crud built up in a high mileage, abused or near end of life transmission. This could lead to contaminates getting into close clearances in valves, bearings, seals and other components. Various transmission types can behave in a different way when new friction modifiers are present. Problems could occur from any transmission fluid change. The use of ATF+4 alone would not damage a transmission. Do your research and decide what makes sense for your application.

 

Unfortunately all that mumbo jumbo isn't what happens in the real world with older AW4 transmissions.
