Why go to a forum to discuss speculative sounds and fluid levels? Just take it to the dealer man! Seriously, if I had issues with my jeep after a few weeks I wouldn't be checking fluid levels and making assumptions of low fluid levels just because you were able to stuff a pint of said fluid in there, probably overfilling till it squirt out the gills and you were satisfied there was something in there. Warranties are there to protect you. Save your headaches for 3 years or 36,000 miles later, whichever comes first, when you can crawl under that puppy and do whatever you please to those dip sticks and fluid levels. P.S. Do not tell the dealer you put more fluid in that bunk tranny. They can use that against you for being Johnny don't know s**t messed up his tranny and we're not covering his mistake under warranty. Just saying, there will be plenty of days down the road for fixing that rig, not when new though.

I did take it to the dealer, and they even had it on a lift to put running boards on. BUT instead of checking fluid level they blew off my complaint of notchey shifting and said it was a Jeep THING!!! AND it wasnt a pint low it was a QUART low!!! Meaning HALF full!! Nothing speculative about dealing with incompetant assembly and dealer service...its a FACT

My bad on the use of the word dummy, probably a little strong, everyone has bad days right? Just frustrating knowing the technicians that day had 2 items to address on a 4 day old Jeep, running board install and notchey shifting, while it was on the lift it would have taken all of 45 seconds to remove fill plug and check level. I could have easily taken their word for it and driven 30k before dumping original fluid.Im sure there was no damage after a few hundred miles BUT Now for piece of mind I gotsta check diffs and Tcase. On the bright side at least the JK has a drain plug (although the placement in regards to exhaust crossover makes one say "REALLY"), My 1980 cj5 with sr4 transmission has NO drainplug at all!! Gotta love the days of AMC....not

My 2012 JKR has 600 miles on it and does the same thing in 3rd and 4th. Was going to take it in just to be sure it's not a bigger problem. Info on this thread was great.

I have also had a grinding noise in 3rd to 6th gears, the stealer has ordered a new countershaft which will be installed in 3 weeks time, hopefully it will solve the problem!!

I just found this a little helpful, I have had a problem with the gears a little putting the shifter in reverse mainly.

Rattlesanke winding noise. Should I be worried this may cause my home to burn down

Can you tell me what issues you were having that they had to replace your transmission?

I also have a '12 with a manual transmission. They did the TSB to fix the hard shit/popping out of 4th gear. However, there's still a rattling sound in 4th, 5th, and 6th. They've had it for a week and I still don't have an answer.

Mine was it started popping out of 3rd. Then it wouldn't stay in 3rd no matter what. They went in, popped in stronger springs (what they said) and other stuff. It didn't work. So they just popped a whole new trannie in. Its kinda..sparingly doing that in 4th but I think its just rpms. Will see how it goes. But MOOSE is home now. WOOHOO!

Why does my brain even try to read..lol.

When I see popping, first thought comes to mind you need to grab some toilet paper and take care of that pooping. Lmao

Your description is exactly what I am experiencing with my 2012. Has 800 miles on it and around the 500 mile mark I developed the same noises.
I removed both shifter boots and went for a drive. Noises become slightly noticeable in 2nd, very noticeable in 3rd and 4th and then much less in 5th and 6th. Noise is definitely coming from the top end of the transmission. Called the dealer and set up an appointment. Made arrangements to have their "transmission tech" ride with me when I egt there.

The 2012 I test drove before I bought mine had some miles on it and the tranny was whisper quiet. So was mine for the first 500 miles. Having owned other manual transmission equipped vehicles over the years and not experiencing noises, I am surprised this is considered normal.

I have had my jeep for two months and decided to check the manual transmission fluid so I know it's good and it was about 3/4 of a inch below the fill hole. I went to the dealer and dropped 30 bucks for a quart of fluid. I filled it to the bottom of the fill hole with the Jeep sitting level on my garage floor and it took 1/3 of the quart to fill it up. Why are out transmissions under filled from the factory? I can't see there being much difference between sitting on its wheels and on the assembly line. Should we be filling the transmission using a level on the frame rails or is it ok just sitting on the floor. I just drove to work and it seemed to be shifting smoother. Also I was surprised that the fluid is a very thin oil.

Does anyone put Teflon tape or sealant on the fill plug? I don't tighten these
plugs very tight as I don't want to damage the aluminum case. The fill plug seems to be leaking a small amount and I am not sure what should be put on it. The drain plug has some sort of sealant on it from the factory.

As a general rule you shouldn't use teflon tape on an oil drain plug. It tends to leave stringy fibers that can plug up passageways and orifices. A transmission probably doesn't have any of those but a semi liquid sealant is better IMHO.

First time back to the forum in a while and its interesting to see that this thread is still alive and that more 2012's had the same problem. Update on my issue is that essentially nothing was done by Chrysler about the notchy shifting transmission, but they did replace the entire clutch drive plate and pressure plate which eliminated the "rattlesnake" sound that I mentioned originally.

I do have an interesting report concerning the low fluid level situation. Basically I don't think it was ever low assuming that Chrysler didn't print a typo in their specs. when calling for 1.6 quarts (51 oz) of capacity for the NSG370. I said originally that I needed to add 16 oz of fluid until it started to seep out of the fill hole. Well when I did my first trans. fluid change I was able to drain about 2.1 quarts (67 oz) of fluid out of the transmission. This means that before I added the extra fluid I originally would have had 51 oz or the factory recommended 1.6 quarts. This means basically that when filled to the recommended capacity, the fluid does not reach the level of the fill hole.

I have changed the transmission fluid a total of 2 times thus far and plan to change it with every engine oil change (4000 miles) because I find that it really shifts smoothest with fresh fluid. I fill the transmission until it is running out of the fill hole when doing my fluid changes because this transmission benefits from a bit more fluid. I was able to look at a parts breakdown of the NSG370 and found that the oil slinger is positioned very low in the transmission housing and would definately be immersed in fluid unless the level was extremely low.

I have about 5400 miles on the Rubi as of now and have learned to live with the gearwhine noise (free satellite radio does wonders for that)....I find that I can mostly eliminate the issue of stickiness and grinding between 1-2 shift just by timing when I depress the clutch and when I drop it into 2nd gear. I find that if I depress the clutch during acceleration it tends to pull out of 1st gear pretty smoothly and then I will usually allow the shift lever to return to the neutral position for a second or two before dropping into second gear which seems to cause everything to line up pretty well. It will still grind a bit if I don't do everything perfectly...although I have mostly eliminated it.

Overall its a great rig....and knock on wood I have had absolutely no other issues crop up since I was last on the forum.

Where exactly is the fill hole for the transmission fluid so I can check on my new 2012? This is the first manual I've owned, so I'm not sure I will be able to identify it if not clearly labeled.

And should this be checked when the engine is cool or warmed up?

Just for what it's worth.. on the Dodge NV5600 manual trans, they had a bad problem of 6th gear eventually going out on them. Many enthusiasts found that by purposefully over filling the trans, the rear bearings and internals would stay lubricated better during operation and it greatly improved the life of the trans. My father has a NV5600 in one of his trucks and wouldn't you know it, he said 6th gear was pretty much gone in it now. Apparently at the factory spec'd fill levels, some parts can still starve for fluid. Over filling is only going to hurt fuel economy and nothing else...so I guess that's why many guys are trying to feed more fluid in there to save the bearings.

I assume that while the NSG370 is a different trans, it likely uses some similar build design.

Bought my 2012 manual a month ago, has just over 1k mi on it, and just 2days ago started hearing/feeling a rattling when between 2-3k rpm; this is just before I generally shift gears. It's been a little rough shifting, which I've thought may just be me getting used to it. I've been a manual trans driver for years, but the car I traded for this JK was a MazdaSpeed3..... Needless to say, that 6-speed shifter and clutch are a far-cry different from these. Anyway, I've made an appointment to take it into my dealership; we'll see what they say.

Our other 2012 JK is an auto.... Completely smooth, no knocking sound ever, at about 4k mi; obviously a different story on that transmission.

Glad to hear it worked out. I was going to post that we are making an assumption that the stated capacity and the fill hole lined up. Seems that is not the case...so to speak.

Regardless...it has a warranty. No sense losing sleep over a mechanical object.

If you offroad your jeep to the level where you need a Rubicon you are likely going to break / ding / compromise the life of several components...hopefully with a smile.

My '05 LJ has the same NGS370 as the JK. I just changed my tranny fluid with Royal Purple Synchromax. I put in probably 1.8 quarts before it hit the fill line. I poured the old fluid back and probably only got 1.2 quarts back. This tranny has 90k miles on it and was somewhat noisy. I just purchased it back in August so I have no idea if the tranny had ever been serviced before. Keeping on topic, I wonder if this tranny has been low on fluid for 7 years? I have my fingers crossed for a long life with this tranny. Feels great now.

rattle noise

I have a 2012 Rubicon and had a similar rattling noise that you're talking about. I took it in three times to have it looked at but they couldn't find the problem as it wasn't making the noise when they inspected it. I finally just pulled into the dealer one day when it was rattling and had them get a tech to come out side to hear it. They ended up changing the release bearing, no more rattling.

Update: going to pick up my Wrangler from the dealership service dept today. This time, they opened the transmission case and replaced the tabs that mount the shifter. They tell me they were worn because I rest my hand on the shifter while driving. This is their third fix for the rattle/vibration issue. Their second fix, done last month, was to replace my shifter with a 2013 shifter out of a brand new manual Wrangler on their lot. Their first fix was to rebalance my tires ( steering was not pulling and steering wheel doesn't vibrate). I'll be thrilled if they've finally found the root cause, but I'm not confident they have. Oh, and I've driven with my hand on the shifter of every vehicle I've owned for over 20 years, never been told it was a problem before today.

You and everybody else... Until I'm in 4th or 5th gear, I pretty much always have my hand resting on there. Seems like a pretty flimsy story on the dealerships part, but good luck!

I just stumbled onto this thread because it got bumped, but I'm switching mine over to Redline MTL soon. Read that really helps with the shift quality in these gearboxes.

I am EXPLICIT beside myself..

Dealership said transmission was fine... (Notchy shifting) well the barely a PINT of fluid that just drained out would suggest otherwise...

YGTBFKM

Seriously folks.. Check your manual transmission fluid sooner than I did.

IT'S UNDER-FILLED FROM THE FACTORY
