I've had similar happen maybe 3 times, but no pop. It just didn't fully engage but wasn't in N. It went into the gate but not into gear. It seems like there was engine "whine" from giving some gas and maybe just a bit of grinding. Twice in 4th once in 2nd if I remember right. I would guess it was most around the 4,000 mile range. Then shifting aging got it set.

Once I had it violently pop out of 2nd. It was on a colder day.

Shifting into 2nd in the past was really knotchy. Now it has gotten much better, but is still a bit of an issue. I think it has to do with the synchro, but I'm no mechanic. I have also found shifting at 2000-3000 RPM smoothes it out. Also I think my timing of shifting is getting more were the jeep likes it. Probably just a bit slower.

Some times when going slow like in a parking lot I'll go from 1st to 2nd and will here a slightly delayed clank in the transmission. I'm pretty sure like the shifter bouncing around, it just a jeep thing.

Now at about 7000 miles it has been driving great for several thousand miles. Hopefully posting won't ruin my luck.

Popping out of gear is a shifter boot quirk. A cold boot will push the shifter toward the position in which it cooled off. After it warms up it's fine.

I have a 07 and I haven't had any problems yet. At 72k I can tell that the clutch has been worn down a little but it still drives fine. This is probably from me learning how to drive stick and trying to off road like an idiot.

I have an 07, bought it used with around 32K, has 42K on it now....
1-2 shift is a little rough but OK.....Nothing other than that.
I just changed oil in it, put in Amsoil Sycromesh fluid ( 2 quarts) Synthetic.
Shifts OK..... No problems. "BH"

I'm having similar issues that are stated in this thread. I noticed a rattle at idle but it goes away when I push the clutch in. I never had the trans pop out of gear though. One thing that bothers me is that I'm getting a smell sometimes when i try to cruise up hill instead of downshifting before starting the hill. The same smell also comes when I accelerate fast, like merge into traffic and shifting fast. It almost smells like the clutch, but I don't think it is. This is my 4th manual trans vehicle that I've owned and I used to drive a cab over Isuzu flat bed for work so I know how to drive manual.

Any thoughts?

I have a 2012 JKUR with the NSG-370 6 speed manual transmission. At about 30,000 km I started noticing a growling/grinding sound in 3rd gear and to a lesser extent 4th gear, which increased over time. When I had the initial transmission, transfer case, and differential fluids change done at a repair shop that I have used for over 20 years I mentioned my observation to them and asked them to note any filings or other anomalies. They strained brass filings from the transmission fluid, suggesting a problem with the synchro gears. They re-filled the transmission with synthetic lubricants and I continued to drive it to see if that made any difference. The growling/grinding sound in 3rd and 4th gear continued to worsen.

I took the jeep into the dealer at about 65,000 km and explained my observations and the filings that had been found in the transmission fluid. They drove the vehicle, confirmed my observations, and replaced the countershaft, associated bearings, gears, etc. The transmission growling/grinding was significantly reduced but not completely gone. When the vehicle was new there was no initially no growling/grinding from the transmission.

Within another 10,000 - 15,000 km the growling/grinding sound was back as loud as before, and after having put another 20,000 km on the vehicle (odometer at ~ 80,000 km) I took it back to the dealer. Again they agree there was a problem and proceeded to do essentially the same repair again, replacing the countershaft, associated bearings, gears, etc. The advisor called me to let me know that the repair was completed, but that it was still making "some noise". I picked up the vehicle yesterday and the growling/grinding sound from the transmission in 3rd and 4th gear is substantially the same as when I had brought it in. Unfortunately it was late on Saturday afternoon and the service advisor I had been dealing with was not in, nor was the service manager.

The conversation Monday with the dealership is going to be about transmission replacement.

Does anyone know if there have been any changes / enhancements to the design of the NSG-370 transmission in the past couple of years?

My 2013 JKR 6 speed with 10K miles has a loud "clutch chatter" that only seems to come on when the Jeep is running hot. This is the only annoying/serious issue I have on my JK. Anyne else with "clutch chatter"? How do I correct this issue?

I have seen quite a few post on people having problems with the 6-speed. It just makes me what kind of percent of people are running into defective transmission issues.

Please leave the Jeep year with any experiences you would like to share. Thanks!

Throw out bearing went going around a corner on a wet street. Chrysler refused to fix it under warranty because I took it off roading. Then why they hell do they call it a Rubicon and it can even stay together on a wet street.

I just dropped mine at the dealership for this. I was also experiencing a creaking/ stretching noise when I pressed the clutch in. When I got to the dealership I had the service floor manager hop in the Jeep so I could take him for a ride so he could hear the noise as well; he said he could hear it and it was not supposed to sound like that. The dealership should be calling tomorrow to let me know what the problem is. I should also note that it happens only when its at operating temp.

Right on brother! Good luck and keep us posted. My chatter doesn't come on all the time. It only comes on when JK runs a bit hotter than normal.

My dealer had to replace my entire clutch at 30,000 miles! Minimal offroading and lots of experience driving the Wrangler 6-speed previous to owning (I am in sales at a Jeep dealership). The issue I brought it in for was a weird squeaking sound whenever I pushed the clutch pedal.

I have that too. *** update*** the dealer just called and said they cant find the problem and they cant hear it, even though I told them that it has to be at operating temp. So I am off to the dealership again to start it up, let it warm up and demand to take a Jeep full of technicians around the block as to ensure that everyone and their brother can hear it and agree that a clutch is not supposed to sound like that. Ill update when I leave the dealership!

No real problems with my 6 speed. It rattles pretty loud in 4th gear when accelerating around 2000rpm. But haven't had any performance issues because of it. I'm not going to lose sleep over it. Also rattles a bit in 2 and 6 but not near as bad. It's jumped out of gear a couple times on extremely cold mornings.

***update*** So after going to the dealership and taking the service manager and one of his techs out for a ride, they said that there is defiantly something wrong.

If the service manager heard it the first time and the second time as well as another service tech; there has to be more to this. We shall see though.

I'll update when they call me about what the actual problem is.

I do have to note that the service department has been great thus far with phone calls and updates.

A quick thanks to my fellow vets out there, Semper Fi.

USJeepMc - yours is the same problem of the loud rattle from 2k Rpm and up in say gears 2-4
Right?


Mine has actually been driving / shifting better. I've never had the loud rattle when accelerating in gears - just a slight rattle / ticking in neutral. I don't plan to take it in any time soon. Probably just going to synchromesh in the coming months.

I kinda hate that we haven't heard from the guys earlier in the thread that were having multiple rebuilds , transmissions replaced, etc.

Did Chrysler ever release a service bulletin or anything?


Thanks

Yes, I have a rattle through the gears and is more pronounced in 4th. I also have a creaking sound when I press the clutch in. I also have a loud chattering sound when the clutch is not pressed in.

I just got a call while I was typing the response on here. The service department said it was the TOB and it was beginning to rub on the the clutch fingers. They ordered new parts and it will be finished up by Thursday/ Friday.

I haven't hears of any bulletin but the tech did say there was another jeep in a few months ago who was having the same sounds, but didnt say anything more on it.

Good luck. I had my TOB replaced (including most of the transmission internals) and it made no difference.

16000 miles on my 2012 JKU with no major problems. 1st to 2nd is a little bit notchy especially when cold. Changing the fluid out receintly for Redline MTL made a noticable improvement, but did not cure it completely.

'12 with 29k, needs a new clutch. Granted I've been doing some light-moderate off-roading and put 35s on it about 4 months ago AND it still only has 3.21 gears. STILL seems really low mileage for a clutch. I don't drive it that hard. Fought with the lady on Chrysler's end to try to get them to cover it under warranty for about 20 minutes. She said that the "clutch isn't part of the power train" which I immediately called bs on. Apparently it's considered a "wearable" item to which I responded "So is the engine. Am I going to get the same response if I have a problem with that thing too!?" She didn't like that too much...

took my 2013 JKR with only 10k miles and told my usual tech rep about the clutch chatter I seem to get. He told me to get it on video the next time it happens before they can touch the Jeep. My rep suggested this so that we don't waste time with the "unable to duplicate" scenario.

I should mention, my JK suffered from a "faulty" clutch when it had about 1k miles. They replaced the TOB and a bunch of other parts. I am hoping Chrysler won't try to have me front the bill on this because even though my JK only has 10k miles, it is about 14 months old.

I have to say I recently traded in my 2012 JK Sport for a 2014 JK. The 2012 was
Herky-Jerky in 1st and 2nd gear. Tranny didn't smooth out until 3rd gear on up.

You know what they say about vehicles built on a Friday. I had driven a clutch for most of my life, so I thought the Jeep clutch was just more truck-like and that's what I wasn't used to. However, 2014 is nothing like that! 1st gear isn't jerky and shifts smoothly into 2nd. I like the 2014 so much better.
