This would not have prevented the recent data breach (technical details withheld), but the following opt-out instructions can prevent future data breaches with other (FCA) third parties. Some level of prevention is within an FCA/Jeep customer's control. See the section on opt-out...

For normal driving, ZF's recommended interval is 93K mi (conversion rounded down from 93.2K mi). I consider this advice, from ZF, to be an extension of "the book". Please note that, from a warranty perspective, ZF is not part of Jeep or Stellantis. For normal driving, the owner's manual says...

Revised on 9/22/25: Hootbro has informed us, in post #233 below, that LIQUI MOLY claims that its TOP TEC ATF 1800 is compatible with BMW 83 22 2 289 720, which is the ATF used in BMW's ZF 8-speed automatic transmissions. Thanks for the catch! Here is the chain of (claimed) equivalence: - The...

First, I'm replying to my own 10-month-old thread because I think that this content belongs here. More than six years after driving my Gladiator home from the dealership, I finally set up an account on mopar.com. On mopar.com, Service Records is located under My Vehicle. There, you can add...

For severe duty, you started with an interval of 70K miles, tempered that with [not] 50K (I called it 60K), then continued the downward trend to 50K or maybe less. For severe duty, this rationalizes 40% to 50% of ZF's recommended service interval for normal driving (93K mi). This equals 42K mi...

MOPAR 8 & 9 Speed ATF (68218925AB) is an exact equivalent to ZF LifeguardFluid 9 (not the other way around). ZF is the licensor. I have read that Shell manufactures MOPAR 68218925AB. I am not a ZF, Stellantis, or Shell insider, but it is evident that the formula and the manufacturing process...

If I add your use case to the survey, someone we know might blow a gasket. I appreciate the info and I'll think about adding it. I imagine a world in which the best expert would address the glaring contradiction in "lifetime" ATF guidance. The contradiction is real.

You used the right word. The first sentence above is debunked, or contradicted, by the second sentence. Why did you leave out most of the second sentence? Here is a running list of service interval recommendations for the automatic transmission. The first step in removing the perception of...

Yes, but FCA doesn't acknowledge the rest of the same paragraph. It's like selective listening.

As already mentioned in my reply to ShadowsPapa, I added a disclaimer to my original reply for those of us with less experience. Thanks for the advice. I am not advising anyone to use a specific ATF. I list several brands of ATF for the automatic transmission in the table in section 1.10.1 of...

Yeah, those calcs needed some help. The expression has 15 characters: 1-(1-6.5/9.5)^3 Change the exponent (3, for three pan drops) to match the number of pan drops. I added a disclaimer to my original reply for those of us with less experience.

I'm reviving this thread to shed some more light on the sequential pan drop replacement rate and the minimum cost of the ATF. Disclaimer: This post is for those who are qualified to do multiple pan drops. Unless you know what you're doing, there are at least some who will say "don't try this...

Summary of Advice on Antifreeze / Coolant for Jeep Gladiator Type of coolant: Formulated with OAT (Organic Acid Technology) Compliance: Material standard MS.90032 (concentrate) or MS-12106 (50/50 prediluted) should be documented on the label or on the manufacturer's website...

I ran across a thread on Reddit about using the coolant reservoir (only) to flush the coolant a fraction at a time. (Sorry, couldn't retrace the link.) The thread lit up like a Christmas tree, but the replies were focused almost entirely on sediment & debris (contaminant removal) and left the...

If you want the details, from each manufacturer, without having to take your own pictures or dig around for the correct web pages, just read post #1 in this thread. When I wrote the original post in this thread, PEAK Purple was relatively new on the market. Both PEAK Purple (not violet) and...

I removed the new section called "Coolant Flush by an Independent Shop". The original post (unchanged), without the new section, is based on content published on product labels and manufacturer websites. For example, both PEAK Purple and ZEREX G30 comply with MS-12106 (prediluted) / MS.90032...

As you saw in post #13 earlier in this thread, I follow the owner's manual or the internal dealer spec sheet. In post #27 in this thread, DavenFla lays out a logical argument to use a thicker grade for frequent trailer towing up steep grades. Although using a motor oil grade different from...

Good question. The old fuse was only dirty. I had never replaced this type of fuse before, so I opted to buy a 5-pack of new fuses ($7.57 with tax) and replace the old fuse.

This fix applies to: - Uconnect touchscreen display / infotainment system - Controls below touchscreen Result: Rapid boot of touchscreen and related controls, including radio and air conditioning This fix has completely resolved the occasional delay and/or flutter of the touchscreen and...

I use 0W-20 because it is specified in the owner's manual. From the online version of the 2020 Jeep Gladiator owner's manual (P138339_20_JT_OM_EN_USC_DIGITAL.pdf): Page 251: "The engine oil filler cap also shows the recommended engine oil viscosity for your engine....Lubricants which do not...
