transmission

  1. 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...
  2. (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...
  3. 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...
  4. 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...
  5. 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...
  6. 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...
  7. 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...
  8. 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...
  9. 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...
  10. Calculator: gear ratio, tire size, speed, etc.

    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), all other cells are un-editable. Update: Added a new tab to easily compare differential ratios in top gear. Also some...
  11. 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...
  12. 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...
  13. 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...
  14. Trans Issue & Clunking Sound (Engaged 4H)

    Preface -- 2018 JL 4Dr Manual Transmission Was down last week in OBX (North Carolina), on the 4x4 beach... put the vehicle into 4H moving below 20mph with no issues, got to my location without issue. Following days, any turning while in 4H, I got a clunking sound like the 4 wheel drive is not...
  15. Loud Clicking under JL? Trans???

    Since day one there has been a noticeable clicking under the Jeep. Id venture to guess its Trans related, although it doesnt necessarily happen during or right before a shift. Im hard pressed to find a particular timing or pattern to it other than it happens all the time and is mostly...
  16. Transmission Flush

    We all know the 8 speed tranny in the JL is sealed. I'm one of those guys who changes my tranny fluid every 60k. Has anyone figured out how to do this yet? We could do the cooler line flush but you need a machine since you can't do the pump out and refill on your own. So that would mean u$$$ing...
  17. Transmission delay

    I have a JL Sahara with 800 miles on it. Both my wife and I noticed a slight delay when putting it in drive or reverse. You put it in gear, press the gas and there is a slight pause before you move. Been doing it from day one. Anyone else seeing this?
  18. Not Shutting Down Properly After Transmission Leak

    I had a transmission leak within the first 100 miles of delivery. Needless to say, I was not happy. I tried to get a replacement vehicle, but was unsuccessful. The dealership insisted it would only repair and extend my bumper-to-bumper warranty. Since I got the vehicle back, on two separate...
  19. I was so happy until I saw this puddle

    I took delivery of my Wrangler JL on Friday 2/2. I immediately fell in love! I had traded my 2015 JK, but was hesitant because she'd been so good to me. On Monday 2/5, I came out to find a puddle under my JL - I suspect it's transfer case fluid. It doesn't smell like oil, but it's viscous...
  20. Which manual transmission for the JL?

    What manual transmission will be used in the new JL? Hoping it's a new 6 speed, preferably 7 - w/ a little more class than the current (NSG370 - 2005 - present). Maybe give the clutch a little more "feel" at engagement w/ a beefier TOB. Not asking for anything sports car minded but would be...
