DaisyCutter I had the 4th gear rattle in my 2013 originally. It's at 13,000 miles now and the noise has been gone for several months.

For the trans, I tilt the vehicle on it's side using a floor jack and overfill the trans with oil by about 6oz to ensure the input bearing gets lube. It's kinda high up there.

saiven This is true
I love my jeep

I just got it back from the dealer today. They replaced the battery under warranty and that fixed the not starting issue.

They said the noises are not an issue.
They said the transmission shifts fine even though when I left I couldn't get it into reverse without going into 1st.

I received a call from my Case manager but it was too late to call him back since I a in Hawaii.

I will keep you all updated on the process.

I really only want a jeep while I am in Hawaii the roads are not the best.
Hopefully he can help me out.

I'm going to take it to another dealer, I don't think my dealer liked that Chrysler called them about my issues. Hopefully the next dealer will help me out.

MnJK Sorry to hear of all the troubles! Very frustrating I'm sure.
One thing to consider before throwing the whole Jeep brand under the bus is that all vehicles (Honda, Toyota, Ford, etc) have vehicles that comes off the line and are crap. Doesn't necessarily mean the EVERY vehicle made is that way.

Every vehicle forum will be loaded with cars/Jeeps with issues because forums are where people go for help with these problems. Folks don't start many threads about problems they aren't having...that would be a bit boring, haha.

Hope the dealer is able to help you out and get the issues resolved. If Hawaii has a Lemon Law, probably would be good to read up on that and see if/when you would qualify.

OMG my jeep has had sooo many issues

Dear form...

I purchased my jeep at WINDWARD JEEP in Oahu Hawaii.
2012 Wrangler Unlimited Altitude Edition

My jeep was amazing and wonderful till around a couple thousand miles...
there was the "Tapping of the vales from the left head"
I took it into the dealer and they said it was normal...

1) They found that the water pump was going bad
2) During replacing the water pump they found the timing belt tension-er was going bad

Took it back numerous times having them tell me that the valves knocking was normal...

3) They finally said it wasnt normal and replaced all the valves...
Brought it home and nothing changed....

4) Spoke with manager and they replaced the left head...
FINALLY IT WAS FIXED!!!! at last

5) I started having issues with the transmission rattling
I showed them videos and let them hear it...
This was so noticeable when i was driving people in ti they said something to me....
AGAIN they said it was normal...

6) Every oil change I mention it and its always normal...
--It has troubles going into reverse and shifting from 1st to 2nd
--When moving slowing and the clutch engaged and in gear it pops/Knocks gently
--Sometimes when I move from a stand still there is a POP sound...
AGAIN all of this is NORMAL....

7) The car dies on me and wont start and cannot be Jumped...
I mention everything again...
I call IAMJEEP and start a STAR case... they get the dealer to look at it.
After a week with no rental car they finally tell the its just a dead battery and they replace it....
AGAIN everything else is NORMAL....

So i should have it back Monday morning....

UGH... my dream car has been a nightmare...
I have had it in the shop so many times and I don't know what to do next...
I Seriously wish someone would steal it or burn it down LOL
PLEASE HELP!!!!

Any advice... i am at 32k miles and it has been garage kept and never off roaded... I know i am horrible... but I have had all of these issues and its getting old fast...

I used to recommend jeeps to everyone... now when talking to people that knows me just sees all my problems and say they will never buy one...
12-09-2014 02:34 PM
ocd_dave One thing that I have been exploring is to run it up a little higher in the RPM's, been running it up around 2500-3000RPM's. The Jeep torque does well down low in the RPM's, so I never felt like it was in trouble, but it seems to contribute to the rattling some.
12-09-2014 02:19 PM
Black_and_Tan My third gear rattle has become very intermittent/infrequent, or I have just gotten used to it.

That said, I now notice intermittent rattling/growling at idle. Nothing too bad, just a new noise.

Almost 10k on my 2014.

I am planning on changing transmission oil soon. At this point just waiting for delivery of a 17mm hex nut.

And the sound is back

I'll go back to the dealer - but at this point the next step I would think is taking apart the transmission. Not sure if I want to go down that road..

My next step is to change out the fluid.

Update on my 2015 WW 6sp...2500mi now.....no rattle ever experienced before fluid change and still no rattle or gear slippage to date. Pennzoil smooth as silk and warms up and loosens faster in the cold winter weather.

Thinking about changing the transmission fluid as others have done.

Their advice was to leave it alone. They've never heard of any catastrophic failures and their experience has been that the sound eventually comes back anyway. My transmission never made the noise until I had about 2K miles on it. I am still investigating this matter and will be talking with a corporate engineer in the future.

Will keep this topic posted on what they recommend, and what the results are (if any) of fixes they do.

Likely a combination of gears, the input shaft, and TOB conspire together to produce the sound at some resonant frequency. The bottom line is that this seems to be an artifact of this transmission. Maybe the next generation (if manuals are still around) will be better designed.

It came back just a few days ago.

Decided to drain the original fluid at 14k miles and replace with Pennzoil Syncromesh a few weeks ago before winter set in. Main reason for the change is it was very stiff in the cold MN winter mornings and thought I'd try synthetic this winter. As others noted, was amazed that about 1 qt cam out but replaced with just over 2 qts. Noticed smoother shifting right off the bat and much smoother shifting when cold (has been down to the single digits at night recently).

The most amazing thing is "the rattle" has now stopped as well. Have gotten so used to the rattle that is seems eerily quiet! Could be coincidental with the trans oil change but interesting nonetheless. Will see if it stays away.

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.
10-24-2014 10:55 AM
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.

Should i push for no lemon? What about all the work and parts have put into this thing? Thanks guys

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.
