Hey everyone. Same problem with my 2012 JK. Rattle in the trans / 4x4 shifter between 1500 / 3000 rpm. Gears 2-5. Mine spent a week at the dealership getting looked at. They replaced the input shaft and bearing they noticed were worn/defective. Mine still has the rattle. Only 4,700 miles on it. After reading everything on here, I'm thinking it's a synchro / bearing issue. Also, I think there is more play in this transmission than previous model wranglers. For me I doubt it will leave me on the side of the road, but it's a NEW vehicle. $30k should get me a rig that is quieter than my '92 YJ...

PS: mine seems to be intermittent noise that is more noticeable during colder temps. Was @ highway speeds for about an hour - temp near 60 degrees. A transmission tech hopped in with me and I COULD NOT get the noise to occur at all. Dead silent... If noise it still occurring when it warms up this spring, I'm getting the countershaft assembly looked at. Good luck to everyone.
Don't forget, this transmission uses auto tranny fluid. Much thinner than the gear oil that previous manuals use.

No it doesn't use ATF. It uses a special synchromesh transmission fluid.

Here's an odd update to this issue. '13 JKU 6 speed. Bought in November 2012. Rattled a LOT in all gears, roughly around 2500 RPM's. Noise would come and go, but was pretty consistent. At 3500 miles, I did my first oil change- went to full synthetic oil. That was 2 weeks ago. Since that time....no rattle. No clunking shifting, no other transmission noises I experienced during the first 3500 miles. Coincidence?? I'm curious how many people who HAVE the noise are running newer models with under 5k miles and still on the original oil? Or how many over 5k had an oil change and don't have the noise any longer? Just seems really odd to me that noise has stopped completely for me. Shifts are crisp and smooth for me now, whereas the gearshift felt very clunky and notchy before, and the clutch pedal too was noisy. It's like I'm driving a totally different Jeep! Weather conditions also have not changed...

I switched to synthetic at 4k miles, but still have the rattle... and it's even getting worse!

I also don't understand how an engine oil change would affect shifting in the case, your shifter, or your clutch... weird.

But hey, that's awesome that yours somehow went away!

MS-9224 spec Chrysler fluid IS an ATF fluid. It's thinner than a normal manual transmission fluid because of the brass synchronizers.

Yes, its thinner (5W-30 viscosity) but it isn't an ATF. If you ever drain your transmission you will see for yourself it isn't an ATF or you can take Pennzoil's word for it: http://www.pennzoil.com/wp-content/u...rans-Fluid.pdf

Check the heat shields underneath, especially the one right under the driver's side floorboard.

I have been following this thread but have yet to contribute. I purchased my 2012 wrangler used "6,000 miles" and noticed a slight rattle when it was at idle in neutral. Few thousand miles later THIS happened.

The good news is that the rattle wasn't related to the broken shifter. Dealer told me it was a manufacturer defect.

Bad news is after I got the shifter fixed it still rattled like before in idle.

This past weekend I changed the transmission fluid with the Pennzoil Synhromesh. No rattle now! Not sure why or how the fluid helped but it did. This might be a easy fix for some of you with the same issue as me.

Ah yes, I remember the "I broke my shifter because I am ham fisted and show no mercy to the weak" thread. LOL

Just kidding. Mine never rattled in neutral.

PS: Once upon a time I researched what exactly is synchromesh transmission fluid. The ones who make it start with a 5W-30 non detergent oil just like they would for an engine. Then anti wear additives (which are yellow metal friendly) are added along with an additive to promote smooth synchronizer engagement.

Both times the dealer worked on my trans, my neutral rattle went away for the first few dozen miles. It comes back. I think it's just the new fluid.

Mine is finally going back in tomorrow for round 3. Fingers crossed. They're going to give me some dirty looks because this is a new service advisor and I also asked them to fix my creaky seat

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.
Since my last post I've gotten a rattle in 3rd and 4th and neutral. I took it into day to the dealership and took the shop foreman out for a ride. He didn't say much on the trip around the block other than they've seen new Jeeps come in with the transmission fluid not being at the correct level. They checked that and it was fine.

I have to take it back Monday where they will tear it down to look for the problem. They did put it on a rack and heard the rattling in neutral.

From my invoice:

"Found grinding noise while in neutral customer to return for tear down on transmission."
We'll see how it goes!

I think mine is a throw out bearing. I only notice it when stopped close to something, like in a drive through, and the noise goes away as soon as I touch the clutch. I've heard the throw out bearings in these things are weak, but I don't think it's really a problem yet.

The service department acknowledges the noises, but doesn't want to try to repair it because they don't know what is causing it. They want me to drive it until it gets even worse, or fails. I have a case open with Chrysler, but haven't heard anything.

My guess is they don't want to attempt repair #3 without knowing exactly what to do because it's 3 failed repairs within the first 2years/24k miles in Oregon for it to qualify for the lemon law. I never mentioned the lemon law, nor do i have any intention to lemon law it, but that's the feeling i'm getting from them.

Mine has been making the noise in gear since about 1500 miles, just turned 4K miles. I thought it was the cold, but now that it has warmed up, it still hasn't gone away. When its in for the next oil change, I'll have the dealer look at it.

I'm kind of surprised they didn't decide to replace the whole transmission.

Called dealer today to check in on progress. Dealer tore apart transmission and called Chrysler with results and Chrysler is actually revamping some transmission mount part, I'll get more info when I go to pick it up today, which is the culprit. The revamped part is on national back order as they have to ramp up mass production of it.

They are putting my transmission back together and I'll pick it up today after work. It's OK to drive and they'll call me back when the part is in stock at which point they'll replace it.

Got Jeep back and this is what the report says(their English no mine):

"Trans grinding and grouling when is 3 and 4 gear. Perform inspection and found no problems at trans perform other inspection and email Chrysler and was told to replace trans mount do to shift location. Mount is in back order at this time. Star case #461597"

I have a rattle when the drivetrain is cold. It occurs as I accelerate, up to about 2000 rpm. By the time I'm down the road at the stop sign its gone.

Question: Is this this manual transmission used in other Chrysler vehicles? Maybe they used all the same "generic" parts used in other vehicles and the Wrangler needed a more specific part to prevent the rattling/grinding.

I'm anxious to hear your results. At least they are getting multiple STAR cases on this.

Not anymore, to my knowledge. I believe it was used in the Crossfire and Liberty.

Here's my latest rattle. Only seems the happen in 3rd. Starts at about 10 seconds. Anyone heard that one before? Sounds like it's coming up through the linkage.

2013 JKUR with ~5000 miles and I have a rattle in the center stack/shifter area. At first I thought it was my hard top but now the soft top is on and noise is still there... 1800-2500 RPM in any gear under load/acceleration. Driving me bananas, time to head to the dealer!
