Scifideity Took mine in again since the problem returned within a week of them doing the TSB actions.

The second time I took it in they ended up keeping it and giving me a loaner while they replaced the "Counter shift assembly" which involved removal of the transmission and had to be done by a mechanic Certified for the type of Transmission work it involved. My dealership only has 1 such guy so my guess is it's a rather specialized certification.

When I got the Jeep back I could notice an immediate change in the way 4th gear felt. Before the work, 4th gear was very loose and rattly sounding when at certain RPMs. 6th also felt and sounded the same way. After they replaced the counter shift assembly, 4th gear feels nice and solid and has no more rattle to it at any RPM. 6th gear improved as well. Before the repair, 4th gear never really felt like it went very far into gear. When it would pop out and I'd clutch again to stop the grinding it never really felt like it went in any further. Now, it is very obvious that I'm shifting into 4th. The counter shaft assembly must have taken out all the slop that was in the factory stuff.

I believe this last repair has done the trick. It's been almost 2 months now and no more grinding or popping out of gear.

Only time will tell for sure.

Scifideity My 2012 JKU has been grinding and popping out of 4th gear since I bought it. It's now at 3400mi and I had time so I took mine to the Dealer today and they replaced the following:

Corrective Action Taken:

Inspected, Replaced Shifter Detent and Shifter Boot per TSB

Part Number / Description

68164693AA / Shifter Transmission
68085312AB / Knob Gearshift
5013477AA / Sealant RTV

So far so good. No problems on the way home but time will tell.

jkg2101 final update from me (I hope). Dealer replaced the transmission with a new unit. Took about 4 or 5 days. Now the problem is gone- all gears shift normally. In the end, it was something in the transmission and not the shift linkage.

jkg2101 Update for those who may suffer the same fate. Dealer had car for better part of a week. Took trans out and apart. Replaced a bunch of parts and put back together. Problem is the same. I guess they fixed the wrong problem or did something wrong. 4th gear grinding when trying to get in gear and occasionally popping out of gear. Service manager spent a few minutes suggesting maybe that is just how jeeps are but I would not have that. This is my third jeep. Now dealer is talking to Chrysler to figure out what to do. Jeep service technician makes it grind just as bad as me and my wife do, so it is not us. Something wrong. I'll spare everyone the minor details, like how I had to ask the technician to wipe the chunks of grease off his hands before test driving my brand new car...
05-03-2012 08:49 PM
jkg2101 played with boot. not the problem
replaced boot and shift handle per TSB on this post earlier. not the problem.

on another forum, several others recount their tale of the same problem. brand new jeeps. had to have dealer take out transmission and replace some part. 3 weeks in the dealership. I have never met a dealership service area that was any good, so I am super bummed. There might be some good mechanics in with the monkeys, but the places are run like a circus.

I guess I have no choice, so I will report on the end result whenever I find out, so maybe the next guy wont get stuck.

the dealership installed those three parts, including the new shift lever, listed in the TSB earlier in this post. It did not change the problem at all.

Now the dealership wants me to leave my brand new car so they can take the transmission apart. i don't trust these monkeys to tie their own shoes. how frustrating!! my brand new car (surprise for my wife) is going to be in the shop for several weeks. And obviously this problem is not unique to my car. obvously a bad batch of transmissions. my guess is something is wrong with the way the gears are installed on the cluster shaft inside the transmission, Hurray for chrysler!

anyone have any more info?
Mine was built Dec 7th of 2011. Started with same problem. New parts installed prior to purchase. Play with the height of the boot over the shifter. Fixed my issue. Needs to be at least 2" from bottom of knob

I filed a follow up question to find out when mine was built and they said 02Feb2012.
I was told if it was built after November of 2011 it should have the new parts. However in an earlier post someone had a later build date but still needed the replacement parts.

demarpaint You shouldn't have to double clutch a new vehicle with syncros in the transmission, something is wrong. The whole point of syncros is to eliminate the need to double clutch. Now it isn't a sports car tranny either, so a slight pause in Neutral before shifting to the next gear might help. Double clutching helps too but is a PITA and shouldn't have to be done. Popping out of gear means something is wrong. Honestly I'd go back to the dealer with it and have them fix or replace the tranny.

Scifideity I have a 2012 JKU purchased on 4/7/12 w/ 253 miles at purchase and 550 now. I was wondering WTF was up with 4th gear all the damn time. I'm glad I found this Thread. Just emailed Jeep requesting my build sheet.

j_pappy Hopefully my jeep will not have these problems..picking it up Thursday..first 3 numbers of VIN are 201 so hopefully it was a later build

ronsol I own a 2012 wrangler with 875 miles on it. When it had 300some miles, 4th gear started jumping out with a grinding noise. After arguing with the dealership they said that chrysler knows about the problem. Picked it up today runs great. I have the receipt with the repairs information.
03-27-2012 12:02 PM
1quick1 I have the grinding issue. I knew it wasn't me as I've drove standards for years. Good info. But of course replicating a completely random problem for the dealer would be fun.

Take your time with it, if you rush it, it will grind. Since I started really paying attention while shifting i have not had the problems. Give it a try before you go to the dealer...

i had my 12 since last august. same problem the day i drove home from the dealer. sure i could manhandle it from 3rd to 4th, but if anyone else drove it -grinding.
this is a new vehicle. shouldn't have to manipulate the transmission. they started out replacing the boot and went through their flowchart of solutions. ended up with a new shift linkage that solved the problem.

moral of long story. don't settle for less. now i can shift with two fingers and smooth as old toyota.

mfaas88 I have noticed that there is two positions for 4th. What I mean is....

Go sit in your rig, leaving it turned off. Move the shift towards 4th gear. You will hit a ledge but if you let go it pops out. Do it again making sure to pull back and it will seat properly.

Then go drive it and try the same thing.

Yeah Im printing it out now. I dont know if itll help, they'll probably just say they still need to "experience" the problem in person. But hey its worth a try. I guess I should just start paying attention to my 4th gear instead of driving...

As far as the rattle goes, sorey bro I can't help ya.
I did the boot thing and it didnt seem to help in my case. I did take it back to the dealer this morning. I test drove it with a tech and it popped. Good times right? Nope. That was around 9am. I call at 330pm asking about my JK. The guy said the two ppl that helped me are goine for the day and that another tech had to test drive my JK again. I get a call backa few minutes later from another guy saying that the first tech that drove with me was only a part time guy...so apparently what he said means nothing to them, so they have to test drive it again. and my time this morning was wasted. At least they fixed the rattle though...

The guy then says that the problem has been noted and that if it continues to happen to bring it in again...I asked what happens from there then. The guy tells me that they would still have to replicate the problem before they can do anything..wtf. I know im not imagining this 4th gear popping, it happens when I'm just driving (and not specifically paying attention to shifting). *sigh Now I have to go back and test drive it with another tech...
