Well heres an update, In the last 6 months my 2012 JKU got a new transmission and for 5000 miles was quiet then the rattle came back.. Right at 2000 RPMS in 2-5 gear.. I have noticed my shifter shakes really bad.. anyone else have this??
So my Jeep is back at the dealer again trans is out and they are scratching their heads.. I also have the squeak when I push in the clutch.. Also with the clutch in and rolling you can here a helicopter noise..
Ive already received the Chrysler Max care warranty for my troubles.. But Dang I really want a jeep that I can drive!!!!

2012 MW3 no issues, just wish the shifter arm was a little longer.

Only 6,500 mi on my 2013 Sport 2-dr but nice to see 85% (of 396) are problem free.
$ leak continues to be an issue though

I clicked "no major problems" but it has always been noisy and clunky. Sold it and bought and auto, no more issues....

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?

The dealer replaced the transmission - Thanks Jeep and Eastside Dodge in Calgary for standing behind your product!

I have a 2012 6 speed with 24000 miles that occasionally pops out of 4th gear. It doesn't happen frequently at all, but I'm going to have it looked at anyway.

I thought I had a problem, reverse would pop out every now and then. Well after seeing what I was doing it is driver error IMO. The gate for reverse is pretty deep and it is easy to just put the shifter over they let out the clutch and you get a grind and a pop. Make sure it is fully engage and there is no problem. Not as smooth as the Vettes but so far no problems.

I have a really strange "rattling" when im ideling. I can hear it REALLY good if im in a drive through or parking garage. As soon as I tap my clutch (and i do mean depress it a tiny bit) it goes away. 7300 Miles and has done this since about 300 miles. Took it to the dealer and they claim its normal (doesnt sound normal) my brother has a 2012 JK and his is silent and normal

is it something i should be worried about?

'09 4-dr. During the first 6,000 miles we experienced popping out of 1st gear with a very loud bang. It was so loud we thought somebody hit us the first time it happened. We took it in multiple times but they never had it happen. Finally I was able to figure out a scenario where I could make it happen. Took the service manager for a ride and was able to replicate the problem. They replaced the transmission and 76,000 miles later it's been problem free ...

'09 Wrangler Unlimited X, Red
'00 Cherokee Sport, Blue - gone but not forgotten
'90/'91 4dr Montero's - gone but not forgotten

Impulse eliminates planning ... that's a good thing

2010 Sport 2 DR 80,000 miles used. This is my first jeep!! I have had it for roughly a month now. It has popped out of first twice and reverse twice. Scared the crap out of me seeing I was in an intersection. This thread has some excellent information on it. Thanks! After reading this I'm hoping that it is just the first gear synchro. I'm going to have it looked at and pray it's not too expensive to fix. If only I could do it myself.

2015 2dr Willys - 1000mi. No problems at all. I do notice the shifting is smoother and less notchy when warmed up. Reverse gets tricky when cold. I plan to swap the fluid to Penzoil Syncromesh to see if that lil querk improves. Definitely a farm truck like manual experience compared to cars. All and all I am very happy with it and have none of internal rattle some folks complain about. Go for it!

I now own my 5th Wrangler and first auto wrangler....this is my second first JK had throwout bearing noise from the start of purchase ( brand new) i never liked it as much as my TJ's ( as far as shifting feel etc) was a 2007.... went back to a TJ/LJ in between....I plan on keeping our 2014 for a long term family hauler and all purpose vehicle....opted for the auto for two reasons...A. during the summer we often fight horrible traffic to our shore points....B. There was less stuff that could go wrong that they could blame on me during my warranty period.....( Chrysler sucks).

2009 jk x

I bought mine used with approx. 37k miles on it. Now has 70k. lately (like in the last 15,000 miles) it has been popping out of first gear about every other day. Sounds and feels pretty violent, occasionally if I'm holding on tight the gearshift hurts my hand. I've heard others describe it as a rear-end collision, and I agree. Since it's not under warranty I'll drive it until it goes completely out. Chrysler has a bulletin for replacement of first gear and the first- and -second syncros. Maybe I'll trade it off before I have to sink more $$ in it. Dang, I love everything else about my Jeep!

13 jku sport 17k. I have had similar "problems" as previous posts. At around 7k in colder temps she would rarely pop out of 4th. When it happened it would be consistent for the day then stop for a few days. I figured I would wait until my next oil change "free from the dealer" before I would bring it up. Needless to say it went away on its own after a few weeks. Time will tell if it comes back but overall I am not impressed by the manual transmission in this jeep. Would I buy it again? Probably, imo it adds a lot of fun to the whole experience but it is defiantly an area for improvement that should not need to be made this late in the game. We have autos with 8 speeds but can't make a decent 6mt... Common Chrysler!

2012 JK haven't had to take it in yet, but I have noticed it sometimes pops out of 4th gear and grinds like a mother fucker. I will be taking it in after I put my lift kit on and get the alignment done.

09 Jku with 50k miles. No issues until about 6 months ago. Pops out of 1st gear at least 6 times a day. Can be really scary at times. Read on here that it could be the inner boot but checked that. It was completely ripped in two places. Haven't taken in to get looked at. Hoping someone had a suggestion...

2011 Rubicon. Transmission is fine , no problems. The shifter boot is stiff rubber and on cold winter days will force it out of gear toward the position it was left in over night. It goes away when the inside , and the boot, warms up. SOOO I leave it in gear 2,4, 6 or R and it does not pop out of those. Then I'm good on road in 6. A little hand pressure on the shifter in gears 1, 3, 5 until it warms up keeps it in gear. It's simple work around for a stiff boot.

My 2012 JKSU had tranny replaced at 21,000KM, still had problems after
Traded that lemon for my
2013 JKSU, I complained about noise at 12,000KM, now at 42,000KM they are telling me the clutch is worn and needs replacement and is the culprit of the noise.
They want me to authorise 10hrs labour to open the tranny then charge me if its not a defective part.
