Got_Mud I had no problems or issues either but reverse got better after warmup on the OEM fluid. I stumbled on some threads (JKforum; jeepforum.com) regarding underfill so that is what prompted me to change it. Night and day after penzoil.

Maybe you could run some wire in there first - creating your own dipstick. I could not believe how much fluid to took on refill, nothing like how much came out.
Thanks, I'll do that. Make sure I'm on level ground, pull fill plug and see what happens. If I get fluid leak I'll just plug it back up, if not Synchromesh it is!

I'm not having any issues with shifting/noises/etc but am paranoid from being on WF too much. Plus its cheap/easy to do so figured what could it hurt.

After I replaced the fluid, I filled to the fill plug edge just enough for a little fluid to drip out - telling me I was fully filled. Again 2qts, much more than the mopar stuff that came out.

I've got about 3K on my '15 JKU and its shifting fine, but I picked up some Pennzoil Synchromesh and a pump today, and plan to change my fluid out next weekend when I do the oil. For $20 I'm happy to just change it out, but if its full I'm fine with running the OE stuff for another oil change or 3.

Is there any way to check the fluid level? The manual just kinda glances over it and I haven't had luck searching online for answers.

tjernagel I have a 2013 with 12000 miles on it. I notice a rattle noise when I start up and when I'm coming to a stop. I've also noticed that as I'm coming to a stop I can fell a "rattle" in the stickshift that goes away if I move the shifter into neutral. It almost seems as if the clutch is not completely disengaging the engine.

When I'm in 4 wheel low and creeping up or down a slope there seems to be a lot of play in the drivetrain.

I do plan on taking my concerns to the dealer to see what is going on.

Feel free to PM me. I'm dealing with this now - not a trans issue, but lemon/buy-back.

My 2010 rattled slightly, but my 2015 is borderline obnoxious, sadly. I think I will check fluid levels over the weekend. Only at 1,300 so I guess we shall see.

Got_Mud Seems this is not that uncommon...Glad I changed out when I did.

Makes me wonder if this what causes long term issues/complaints with the 6MT as most normally would not change fluid until 30-50K. Underfilled? Too little too late?

Since changing to pennzoil there is better low temp performance, smoother less notchy shifting, and more for the internals to swim in.

I have had many manual wranglers in my past and this is the first with any issues and when it does work it sucks to drive. The motor is awesome and needs a great companion tranny. I feel bad even saying it but I wish I would have got an auto. Whats next??
And that's why I'm afraid to even take my jeep in for the issue. I mean it works. And the rattling is annoying as hell. But I don't want them throwing parts at it hoping something will fix a problem they have no clue of what exactly is wrong. What's even worse is to hear they have no clue of what they're doing. I'd lose confidence in them immediately. I'd probably worry they'll break something else in the process.

Mine started to rattle now in 1st and third. It's not all the time either. It comes and goes. Sometimes it sounds like a bushing or something just needs to be adjusted.

I have used Royal Purple Synchromax in past Jeeps and it's pretty good. Don't know much about the Red-Line product though.

al2ride I've noticed three issues with my 2014 6-speed. One, it shakes a lot during uneven roads and I deemed it normal. Two, it has a light clunk-clunk rattle type of noise only while in 3rd gear. I'm keeping an eye/ear on that one. Three, while ~55mph in 6th gear you can hear/feel a slight oscillation throughout the cabin. From experience, I would say it's an unbalance driveshaft. No issues t 70+mph. I noticed this one this past weekend on a long highway trip. I did a quick look and didn't see anything caked on the DS.

Any others with similar issues.

Edit: I just read more into this thread and see that the 3rd gear rattle is common.

Gord P Try a different dealership. You deserve better than that.
08-05-2014 03:38 PM
DannyV So the dealership says that the clutch and TOB are wear items and are not covered under 3/36. I explained to them that this has been a recurring issue so we take a ride (3 different guys). One guy says her can't hear anything. One says I hear a rattle but it sounds like gear mesh and drivetrain noise (he also says he heard some spark knock - but I chose to ignore that for the time being) and the last says he hears all kinds of noise but no rattling. He then goes on to tell me that he can tear it apart but, if he doesn't find a bad bearing he will charge me. I got the impression that he wanted to scare me off and if I did leave it they were just going to let it sit in the lot and then charge me for service the next day. This is seriously pathetic. I am seriously disappointed in Chrysler/Jeep.

reddoak I have an appointment to get my 2013 looked at next Tuesday. It's got the clutch rattle, step on the clutch it goes away...

I'm at 18k miles. Hopefully it isn't an uphill battle.
07-22-2014 11:16 PM
insylem A friend of mine was just commenting yesterday that it sounded like I have a valve tapping. But I don't It's either the tranny or the clutch rattleing. The noise goes away completly when I push the clutch pedal in. Most the time it stays quiet after I let the clutch back out (in neutral) and starts back up later or right away. I think wiht me it's the clutch, but I'd hae to crawl under it while it's running and have some one cycle the clutch to be sure.
07-22-2014 09:43 PM
DannyV After my last time in the shop the tech couldn't hear the rattle in any gear and I didn't press them. It is hard to hear.

A few days ago my carpets got wet and I had to remove them. This is the first time I have ever had to pull the carpet from Wrangler. Wow do those make a difference! Since pulling the carpet the rattle is very prominent - in all gears. If I press the clutch the rattle goes away. I will be heading back to the shop next week.

We'll see what they say.
Good luck with it. Let us know what they say.

jj77 Mine rattled originally. My gear box just got quiet after 5,000 miles. It shifted poorly for the first 3,000 miles. I thought I might have forgotten how to drive a manual. Reverse was almost impossible to get into. Now all is quiet and the shifts are smoother. Reverse is still tricky at times. But I'm okay with that. The clutch is unpredictable as well. There is a break in period on the manual transmissions.
06-24-2014 09:55 PM
Black_and_Tan My third gear rattle continues to be intermittent with no apparent pattern. Sometimes days go by without it presenting itself.

It made itself known last night.

Anyhow, I was at the dealer for other warranty work earlier today, and asked that they document this issue. Of course, the mechanic who took the jeep for a test drive did not experience the rattle.

rdg04578 Time will tell on the durabilty of this transmission but most things I have read is it is considered a medium to light duty transmission which will probaboly be fine with minimal modifications and light off roading. Kinda like the AX-5 and AX-4 were in the early wranglers and late CJ's
