  2. JL “HOPPING/SLIP” WHILE HIGH RPM???

    Hey everyone so I have a 2022 JL 4 door Rubi. 3.6 Manual. I put BP gas in it, 87 as manual says. One thing I have noticed, and it has been noticed mostly in third gear while I am at high RPMs (above 2,500) probably around 37 mph and still applying gas pedal, I noticed that the jeep feels like...
  3. Clutch Failure

    Has anyone encountered a similar issue? One of the clutch spring straps (not sure what they’re called) broke and tried to cut my bellhousing in half. Not sure if this is common or if this is unique.
  4. JLURD aftermarket transmission cooling options - seeking suggestions

    Hi, after doing a disappointing shakedown run on my JLURD yesterday, one of the many issues experienced has me thinking about an upgrade. for those that are using the diesel as intended (i.e. towing, heavy overland builds, or heavy offroad usage with lots of weight) i am wondering what options...
  5. New JLU Rubicon 392 broken again

    I received my Hydro blue 392 about 6 months ago. The first time it left me stranded was on a trail. Just a dead battery. No room on the trail to jump, so I pulled a friend's battery and carried it down the trail to get the Jeep started. Dealer tested and replaced battery free of charge. Had to...
  6. Transmission Swap Auto to Manual?

    Ignorant question but is it possible to swap an automatic transmission out for a manual transmission? Looking at random parts and saw the transmissions, which made me think, is it possible and would it economically make any sense over buying a new Jeep? The reason I ask is while I bought an...
  7. 8-Speed Automatic Question

    I just recently purchased my first Jeep JL 4dr Willys. And for the most part absolutely LOVE it. My Gf also purchased a Willys and having driven both through different parts of our community, I notice that mine tends to hold itself in 7th gear longer at 70-80 mph…obviously impacting fuel...
  8. Is this turbo whine or something else? Help me diagnose.

    So about a few month ago I started to notice this whine upon acceleration, sounds something like a police siren going off in the distance. With that said, if I'm in Park or Neutral and just give it gas, it doesn't make this noise. Nor does it make any when coasting. I have to note however that...
  9. (Question) Differential / Transfer Case Fluid Change

    Long Story Short, I'm getting a new transmission under warranty. That Jeep dealership called me that they needed to do a Differential/transfer case fluid change. The service would cost me $700 :CWL: So I said no, I'll go somewhere else But in all seriousness. The JL has 3 spots for the change...
  10. JLU RPM and 8 speed shifting issues?

    Hey everyone - recently just purchased a brand new JLU Sahara with the 3.6 V6 Etorque 8-speed auto trans and it has always been my dream to get one! Had the MOPAR 2 inch lift put on at the dealership, and currently running 35s. Not sure if it is a Wrangler tuning issue but it seems to never want...
  11. Possible damage without shifting to neutral before putting into 4L?

    Like the title said, what are the possible damage that could be caused without putting my transmission to N before shifting to 4L. I had someone drive my Jeep yesterday on the trails and they forgot to put it into Neutral before shifting to 4L and there was a big jerk and some grinding noises...
  12. Fire result of transmission failure

    So my new wrangler JL with the 3.6l and the 6 speed manual decided to self detonate. It happened on 12/21/2019 and as of today FCA and Jeep refuses to speak with me whatsoever. After researching night and day and doing a lot of digging, it appears this is not as uncommon as people think. This...
  13. Water in the Trans / moving tubes

    So my 2019 JLUR took water into the transmission somehow during the Georgia Jeep Invasion. There was a period for about 45 seconds where we traversed a “mini swamp” that came to the bottom of the doors. I figured this is where it may have happened. My warranty claim was denied by the garbage...
  14. Electronics Issue in the Outback

    I'm looking for some advise from the electric/electronic experts on the forum. A week back I was stranded in the Maze, a part of Canyonlands in Utah considered one of the most remote areas in the lower 48 states. Here is what happened: We were camping in the Dollhouse area of the Maze for two...
  15. Vibration at Idle and During Acceleration

    2019 JLUR, auto transmission, 3.6L, almost 13,000 miles. Three days ago, I noticed my Jeep vibrating at idle while in drive. The vibration was noticeable in reverse but not as bad. If on level ground, no vibration in park or neutral. On an incline, the vibration is prevalent in park, neutral...
  16. Potential Transmission Issues?

    Hey all, lately i’ve been noticing that during a start stop event with the jeep starting back up I feel the trans shift into gear with a rough jerk that unsettles the entire drivetrain. I ask that it might be a potential trans or pcm issue because earlier i was reversing in parking spot and...
  17. Calculator: gear ratio, tire size, speed, etc.

    9/12/24 edit: Feel free to repost this anywhere you'd like. I just ask that proper credit is given. Don't be like Gus. Here's a spreadsheet I built to calculate gear ratio, tire size, speed, etc. The yellow colored cells are how to control the inputs (either drop-down or number fillable)...
  18. Just over 1k miles and suddenly hard shifting?

    We are at just over 1000 miles and all of the sudden the 2019 JLU Sport is shifting hard when you slow and it shifts down to 1st gear. Also, going up into 2 seems to be similar. Called a local dealership and they can't look at it for almost 3 weeks. What's the best course of action in this...
  19. Transmission...clutch slipping?

    Hey y’all new JL owner switching from my JK as a Christmas present for me after deployment. This is also my first manual in a few years (was driving a manual work car overseas). Not sure if this is isolated or not, but after 2k miles when I go to 4th gear and accelerate to about 3k RPM, I hear a...
  20. Finalizing a JL 2018 Build

    Hi All, BACKGROUND So I've been working on this 2018 JL Rubicon build (https://goo.gl/pEDi1S) for a while now, it's all coming together slowly, but I wanted to get an opinion from people other than those that are selling the vehicle to me. I will not be going for hard-core rock-crawling: if...
