Anyone experiencing a sort of clunk sound when you shift to reverse? Never noticed this before. I have about 3,000 on my JGC Overland. Just wonderin?

Same issue here... still at 900 kms. Took it in about 6 days back, no issues. No worn bushings, mounts,...nothing. They couldn't even change my windshield water tank coz it was still full :)

The sound is still bothering me, however. It was NOT like that when I first drove it home.
The fact that the service manager gave me no "guess" as to what this might be made me doubt their ability to diagnose future/more complicated problems in the future (hope they won't ever show up!).

Okay, so the clunk is now really bothering me. I'm not so sure if the sound IS getting louder or if I'm just becoming paranoid everytime I pull into my parking space ! I'm taking it in next week and if I get this "everything's alright" attitude from any of the service advisors I'm gonna make some noise this time.
Geez ! Putting this vehicle on Reverse is like backing up an M26 Pershing now ! and I'm getting a reallly bad feeling about this.

It comes and goes based on how loaded the drive train is. When I pull into the garage and have the wheel cranked over hard it will "clunk" when I take it our of D then clunk again when I take it out of R after having cranked the wheel over to the other side and backed out a little. Moving in a straight line it doesn't clunk much at all. You can fell the drive train unload when you take it out of gear, that's what the "clunk" is.

Every 4WD vehicle I've had in the past 4 years since I've been living here and having to jockey the vehicle around getting it into the garage has done this to some degree. If you press the brake lightly, just enough to let the shift lever move, the clunk is either minimized or non-existent because the drive train isn't pushing against the brakes and loading up as much. I will say the WK2 is more sensitive to this but acts very similar to my father in law's Ram pickup which uses the same trans.

I attribute it to the way the torque converter is designed, it keeps a higher load on the transmission at idle where other automatics decouple the engine from the trans a bit more. It seems to be getting better with more miles so that lends credence to many who say a lot of the drive train harshness works itself out over time.

Seems about right. I get the clunk only if I went I go from P to R after it was sitting on an incline.

I'm at 3000 miles as well..

I totally have noticed this issue. I have the V-8, and I have also noticed it when the engine is cold in the morning and I put into drive. I called the dealer and he told me to bring it in (which I did) and of course he found nothing wrong and it did not happen while I was there.

But it happens often enough for it to bother me...

What gives :nono::nono::nono::nono::nono:

Well, after surfing around on the internet....I found this forum. I have a 5.7 Limited. Yes, I have the same clunk issue that drives me nuts and it is LOUD. It is most prevalent from D into N. I have only had the vehicle a week, but it was doing it from the first day. I took it in and the mechanic verified that it was not "normal." He brought up another 4x4 V-8 and we compared the two. Mine was noticeably louder. So, they want me to drop it off and leave it for a day.....and they said they can't give me a loaner. Sigh. Really? A week old purchase and you can't give me a cheesy fricken' loaner for the day?

Same god-awful noise here too...Wife was driving yesterday and pulled into Autozone, pulled into spot and put it in park and CLUNK! I was exiting the vehicle and snapped my head back at her and she gave me the wtf was that look...haha. She convinced herself (but not me) that she probably didn't have break pressed all the way in. My purchase was barely a day old when we heard this. I tried to recreate the problem and noticed it when backing into the garage and shifting from R to P.

I'm tempted to take it to the dealership but I know I'll get the same result as most of you and they'll say everything is fine. Hope it works itself out over time; currently less than 900 mi. on the odo now.

It doesn't matter what response you get from them. TAKE it to the dealer to record a complaint, so that if you ever end up in a dispute about what could become a big problem you would be able to have some legal recourse. One big reason why recalls are announced is due to recurring customer complaints.

mine used to do that a lot. I live in an area where the hills are pretty steep and I occasionally put the vehicle in neutral when coasting down the hills. It's fun to try and coast for 2-3 miles in neutral. :) When I put it back in Drive, it used to hit really hard but it doesn't do that anymore. I did noting that the normal shifting through the gears was pretty rough but it has cleared itself up. I have about 6000 miles on my Jeep not and it keeps getting smoother.

My 1500 mile trip on the highway seemed to finish the break in of the vehicle. :)

It's not a good idea to put it neutral then back in gear as you will **** up gear box ;( at work we have had tail shafts & gear boxes come apart from it !and the under ground cars gear box are stronger !

:popCorn: I have 20,000 miles on mine and it just started Friday night. I was driving to pick up my son, got to the parking lot and put her in Park. All through the shift pattern from N to R to P it clunked loud. It freaked me out! I'm calling the dealer tomorrow and see what they say. This is not going to be fun trying to figure this one out........

I don't have a "clunk" but i'm pretty sure the torque converter is slipping in mine. I've taken it in 5 times over the last few months for the "shudder". All TSBs were applied and it's still happening. They want to add an additive to the tranny fluid.

ha, my ***. band-aid, much? Sometimes i'll have some noise in between park and reverse, but it doesn't seem out of the norm... usually on embankments, etc.
