2013 Jeep Wrangler Unlimited Rubicon Transmission (A Plea for Help!!!!!)

When I first started these posts my Jeep had 14 miles on it. It still has less than 2000 miles and it’s setting at the dealer right now for the 3rd time (in less than 2 months) and they have no clue how to fix the problem.

The issue I have is an intermittent noise, rattle or vibration from the base of the gear shifter usually between 1,800-3000 R.P.M. It seems very much tied to the outside temperature as well. The noise usually only manifests itself on days where the air temperature if greater than 85-90 degrees F.

The dealer has tried to re-torque some things but yet the problem persists. What the dealership did try to do they did not do of their own accord. Everything they tried can from the manufacturer. My daughter and I finally documented the problem and uploaded it to you tube. Please listen to the noise and let us know if you have this problem and were you or the dealership able to eliminate the problem.

Sound like you have them working it, even if it means calling over your dealer's head.

Read through this if you haven't

http://www.wranglerforum.com/f33/201...ll-201153.html

Mine is rolling up on 4K with no transmission rattle (JK, 23R).

Just keep on 'em. They'll make it right.

Have you tried to hold the shifter to see if it still makes the sound? Seems that it only makes the sound under load. Did the dealership replace the shifter unit yet? A pin or other small piece might be loose.

No matter how tight I hold shifter it does not make an impact. You are right only under load does it make noise. Dealer has not done what you are recommending. Thank you.

A mustang of mine had a similar issue and thought it was the exhaust. We tightened everything. Turned out to be the throwout bearing on the clutch.

That's definately not normal. The only sound that's normal is the two "clicks" when you shift. Seems like an internal problem with the trans., but that could be a number of components. I bet they decide to replace the trans. The first thing they should have done was to change the fluid and see if there was anything regarding contaminants, etc.

Mine had the same rumble between 1700-2300 rpm under mild acceleration, it started at 200 miles and has gotten much better at 4000 miles. There are a few out there with this particular noise and my local dealer has been working with Chrysler to find the problem. In the latest attempt the transmission was removed to check the pilot bearing and I saw no evidence of any problem. My dealer is working on it and chrysler takes about 3 days to offer new solutions. From my research on other forums there are about 3 types of "transmission" noises and on your particular example I have seen video on about 3 different vehicles. Through the troubleshooting efforts recorded on other forums it does not appear to be in the transmission, I cannot 100 percent verfiy the outcome but, Jeep Rebel seems to have had his fixed by replacing the engine, he did not post any results after engine replacement so I dont know if that is the end of his story.
The three most common items troubleshot for this type of noise has been loose gear shift knob, transfer case cable rubbing under the shift boot area, and the normal gear rattling for this transmission. I have not heard any cases where replacing the transmission has fixed this noise.
The rumble is generally noticed in 2,3,4, gear but may be occasionally found in 1st or 5th gear. According the the shop foreman, whom I have dealt with for the last 4 years, Chrysler is aware of the problem.

I think Chrysler is aware of the problem but is not able to publish the corrective action at this time for one reason or another. There have been serveral vehicles that have been traded out by chrysler due to this specific issue.

You may have an internal problem with your transmission or you may not. Being that you have low mileage, I would drain the transmission oil and pay attention to the magnetic plug. If the oil is clear and only minor fuzz on the plug, I'd fill it up and drive it. If it's still doing it at 10K miles, I'd question it. At 10K, it's still under warranty anyway and if it does have a problem, the noise will be more obvious and easier to explain to the service manager at that point.

A transmission also goes through a break-in period and I bet that noise smooths out. It gets louder when it's warmer because the oil gets thinner when it's hot. Any transmission gear noise gets amplfied through the shift lever.

Start it up, put the E-brake on and with the shifter in neutral, put your ear on the shift knob. Works like a stethoscope!

I know it was suggested holding the shifter, but hold the transfer case shifter or put pressure at various places around the plastic by the shifters and see if the rattle changes. I have the same noise under load, but I traced it back to the transfer case shifter hitting the plastic or something under it. It still does it, but when I get annoyed I just push the transfer case shifter forward a little or apply pressure and it stops. It's not right and it shouldn't do it, but I don't suspect a mechanical issue on mine and would rather not have the techs digging around since the success rate has been pretty low.

Keep us updated, I'm curious to hear if they fix it.

I hate to say this ... but I do believe you might want to look into the Lemon law if they cant fix the issue. If I do recall they have 3 opportunities to fix the issue. I hope it does not come to that.

Good luck

My first guess would be a bad trans.. that sound is totally not normal. Hope you get it all figured out.

I had the noise manifest itself to a large extent yesterday on my way home from work.
At the time the noise was at its worse I had the shifter knob in place. I turned around and headed back to work.
I then removed the shifter know and headed home again. The noise was as loud as it ever was. No worse but no better.
I do feel it is very possible the shifter know can contribute to some noise but that is NOT what I captured in my videos.
I’ll keep trying. Thanks so much for everyone’s input!!!!!

My 2013 JK made a little buzzing noise when new but nothing like that, and quit after about 4K miles.

Make the idiots replace the transmission. Don't take any BS from the dealer.

Mine does the same thing intermittently. Try throwing it in 4hi when it does and see if it goes away. Mine did. Mine hasn't done it in a while, therefore I haven't taken it in. They won't be able to duplicate the problem.

I'd try changing the transmission oil, although I doubt that would work. I'm thinking it is bearing inside the transmission.

I have had a few posts over the past few months related to a noise I was hearing in my 2013 Jeep Rubicon. The posts I started were entitled…

• “2013 Jeep Wrangler Unlimited Rubicon Noise”
• “2013 Jeep Wrangler Unlimited Rubicon Noise rev2”
• “2013 Jeep Wrangler Unlimited Rubicon Transmission (A Plea for Help!!!!!)”


There was definitely a noise for sure but it was NOT the transmission!!!
If your Jeep is making this noise then I know the problem for sure…



I did not figure it out. It was only through the forums that someone (user “kta2402”) had the right answer.
There is a cable that connects the transfer case shifter knob to the transfer case. The cable is very similar to a bicycle cable. There is a hard outer sheath with an inner cable that actually moves (extends or retracts) relative to the outer sheath.
This hard outer sheath has upward pressure on the underside of the center console. Under certain conditions this cable “rattles” like craze. See image below (I stole this image from user “kta2402”…)


While you are I there check the wiring harness as well. I recommend wrapping both with something soft. Once you do there is no more noise.

It sounds like the noise varies according to engine RPMs. I would guess something in the rotating assembly, perhaps driveshafts or the flywheel? Good luck!

My 2013 automatic makes a similar sound that is dependent on load and temperature. I always thought it sounds like something vibrating against the plastic behind the area of the a/c. Please let me know what yours was.

My jeep dealer re-tied the heater hoses behind the glove box and the noise terminated. Call and speak with Chad, the service MGR at Cals Jeep in Seaside, CA...
these guys used a stethoscope to find the problem... may be a TSB about it.
