2013 jk 6-speed manual transmission "rattling" noise poll

I have a 2013 JKUR on order, and noticed many guys on various JK forums complaining of "rattling" issues with their 6-Speed Manual Transmissions.

I would like to ask all new 2013 JK owners with Manual Transmissions to "chime-in" on this Poll, and elaborate with posts as you see fit.

Thanks in advance.

I voted that my Jeep makes noises, but I'm not convinced that it's actually a problem. My transmission does make some wonky noises when I shift, and I can feel the engine shift in its mounts when I'm in sixth gear, but I haven't actually had any problems with my Jeep yet, thankfully!

No problems just a slight rattle in the trans that I've heard in hundreds of other manual transmissions in other vehicles.

Rattle.


You know this is pretty common right ?
I hardly call it an issue. It's a jeep
The tubes or whatever behind the glovebox sing to me in the morning also.
Again ... I can can less

Transmission rattle might be common but that doesn't make it right. And the "it's a Jeep" doesn't justify it either. Know why? I had the rattle, it was repaired due to a defective part and now the rattle is gone.

I do agree with you. was yours excessive ?
Honestly the first I've seen fixing the "wrangler rattle" <--- yup it has a name
I guess if you push hard enough you can get anything fixed. But I know damn well if I myself rolled into the dealership with this issue they would laugh.

Mine makes a "rough" sound when driving steady at around 1800-2300 rpm. My brother also has a 2012 manual and his Jeep makes about 10x more of this noise at the same rpm range. Both vehicles have around 8000 miles. I'll have it checked out at some point. It doesn't worry me much and I love the 6 speed.

Having owned other manual tranny vehicles in the past, I have a good idea what sounds normal and what doesn't concerning the transmission.

Sounded like rolling marbles in a can whenever accelerating in 3rd and 4th gears. One test drive with the shop foreman and he agreed not normal. No pushing, threatening, or arm twisting involved. Dropped tranny and replaced countershaft assembly. Problem solved. Others on the forum have had repairs done for the transmission rattle.

My 7 year old pickup with 100K miles has a few groans and moans. I would expect that. But not on a new Jeep. It irks me that some folks pawn it off as "it's a Jeep thing".

That's what I hear. A very slight marbles in a can. I guess I've become used to it.
Others don't notice it. Very minor.

Maybe tolerances within that part of the tranny are not all that tight. Someone might have issues and some don't. But not meaning there's is a actual problem ?

I bought mine used but I can see a brand new vehicle I would have looked into it more.

My rattle is in neutral when the Jeep is warm. Push the clutch in and its gone. It did this in both of my 13s since day one.

I have 2012 jku with 4k miles on it. and does the exact same thing as urs does agoldxj. I just had the dealer check it today all they did was top the tranny fluid off that was about 3/4 of a quart low but still had the same noise once I left when ever I came to a stop. Anybody have any ideas???

My Jeep is an Auto, but a friend has a 2013 JKUS with a Manual which has been in the shop more than in his driveway due to a transmission rattle.

I've noticed a rattle in mine also, not excessive, and can't hear it on the road, but hear it at the drive thru window. If I'm in 1st gear, and push in the clutch to coast to the window it def sounds like marbles in a can. When I first heard it I was concerned, now I'm used to it.

What I don't like about the manual Trans, is how finicky it is to drive. I've owned so many manual Trans trucks and jeeps and they were a blast to drive, but mine, it's a pain, wish I bought an auto. Very jerky, seems like the clutch and gas pedal are out of wack. I'm blaming it on the accelerator delay

I've driven all manual vehicles since 1987 and my new 2013 JK 2-door transmission so far sounds fine. Shifting is solid and not hearing anything out of the ordinary. I am finding it to be a bit finicky between the gas and clutch though. Might be I need a bit more time but I'm used to just gliding through gears in my 2007 FJ without all the herky jerky I'm getting now.

I've had my trans out twice and soon to go back again for #3. They replaced a rear bearing in the trans the first time and replaced almost everything the second time when that didn't work. Here's what it sounded like after repair #1. I have both idle and at speed rattles.



Here's what they replaced in round #2:


After driving a month after the second repair, my transmission now rattles worse than ever. It sounds like it's going to blow apart sometimes. lol.

Re: JK 6-speed manual transmission "rattling" noise

Hey doc5339

I live in Canada and bought a used 2010 Jeep Wrangler Unlimited Islander from a local Jeep Dealer in my area that was 1 year old with 33,000 km.

After about 40 days I started to notice a noise from the clutch, trans area.

Before I go any further I will tell you that I am a licensed mechanic with over 40 years experience.

The rattle noise that I was getting was noticeable when I shifted gears or accelerated or de-accelerated in every gear except 1st or rev (highter gear ratio in these gears) .

I suspected a clutch disk problem so I took it to the dealer and they pulled the trans and replaced some parts, but the noise was still there.
I told them that I thought that it was in the clutch and they pulled the trans again and pulled the clutch assembly.
The problem was the springs in the clutch disk were almost following out and this was causing the rattle noise.

Problem solved, but I had to pay for the disk which I disagreed with because the friction material was not worn but the springs were faulty.

After 4 months the noise is back and I am fighting with Chrysler Canada to get them to make a correct repair.

There is a TSB on this problem reported for 2008 JK models.

PS: All other possibilities were eliminated before repair was made.

This seems to be a common problem with the JK and Unlimited.

Keep me advised.

No issues here. It is very clunky and takes a few weeks for an experienced manual driver get a hang of. It feels like there is some looseness or play in the syncros and because its the same on every one I've driven I assume it's normal.

Also, I'd test driven 1 with 1 mile on the odometer which had a serious drive line clunk every time the clutch is released. I've noticed they all do this to varying degrees. The bad one I'd driven sounded and felt like a totally bad u joint. It's very subtile on mine, but it has me wondering.

No issues, no noise except the light vibration you get if you rest your hand on the stick. But I only had my new JKU for a few days, so I may not be a good sample for this poll.

And also no problem rowing the stick (even if my last experience with a manual was 17 years ago). All I can say, I'm having so much fun with my new JKU and when I,m feeling down, a quick drive in 'Dozer is worth any super-pills or therapy!

My 2013 with 2,100kms on it has a slight rattle in neutral with the clutch out, such as when waiting at a red light.

I guess i'll wait until it gets any worse to have it checked out. It still drives fine - at least way better than the 6-speed that was in my 2005 TJ which was the first year for the NSG-370. It crunched going into 2nd more often than not.

Mine rattles slightly, but only while coasting along in 4th gear.

I haven't decided whether or not in annoys me enough to take it in for repair...

I have a 2013 JKU Sport w/ 2,000mi. I hear a low pitch rattle/gurgle at 1800-2500 rpm in 2nd thru 4th gear. I don't know much about engine/trans so I just assumed it was just part of the package. Reading a lot today indicating that it may be a problem, not much clarity on any of the 4 or so forums.

I figure I will continue to check forums until I find a concise answer about it.

My 12' 6-speed rattles when going through 2, 3rd 4th on most days at low RPMs (1000-2000) and goes away as you approach 2500 RPMs. It only annoys me because I think it makes the jeep sound cheap. And it wasn't. But it hasn't bothered me enough to get it looked at yet. I thought I remembered reading something about a loose heat shield? Surprised that hasn't been mentioned in this thread yet. That's definitely what mine sounds like...some thin metal vibrating against some other piece of medal. That would also explain why it's only present in certain gears and RPM ranges...
