I have a brand new 09 Unlimited X 4 door with 2700 miles. This past weekend the transmission popped out of first gear and into neutral when starting from a dead stop - have to immediately shift to second gear. This has happened 3 more times since. It has only happened when starting from a dead stop in first gear and depending on the RPM the popping out can be quite violent - enough to hurt your hand. First time it happened I thought someone had rear ended me. I have it scheduled at the dealer. Searching the web I have found that this seems to be a fairly common problem but I havent found the cure yet. Anyone have any insights?:mad:

My first 08 did it in second but my hand was on the shifter and I probably had applied some pressure to it just before getting ready to shift. It was under power and when it happened, the jarring on my hand and the noise really caught me by surprise. Had to check for skid marks :D.

It didn't do it again and it hasn't happened on the Rubi.

Haven't heard of that. We're at about 7k and haven't had that happen. Let us know what the dealer has to say.

Spoke too soon! At 7,777 miles I experienced the rather violent and very loud pop out of gear from a stop. As jtmdaniels mentioned also, my wife said it seemed like someone rear-ended us. Then again about 10 miles later I experienced a smaller but similar situation when downshifting to 2nd gear.

Very bummed. I'm hoping it was an anomaly and will quietly go away but must admit a bit skeptical.

I have a 2009 2 Door Sahara that I purchased at the end of March. Around 1500k the transmission began popping out of 3rd gear. It was a pretty violent popping out, much like you guys described. I took it back to the dealer twice and never could get the transmission to do the same thing for them. On the third trip back it finally popped out for a tech that was riding with me. They kept the jeep and ordered new parts for the transmission that they said would "fix" the problem. The parts were on back order so I had to wait a week before they even began to work on it. After the parts were installed they called back to say that the parts did not fix the problem and they were going to put a new transmission in. I waited another week for the transmission to get there. Once it did, they put it in and called to say it was ready. I picked it up and on my way home it popped out of 1st gear!!! I immediately turned around and took it right back. They ordered another transmission and I waited another week. (i had a crappy little dodge caliber for a rental, which they paid for, this whole time...almost a month) Once this last transmission came in and was installed I finally got my Jeep back. I've had no problems since and I'm at 5500k. I hope that's the last of my troubles with my Jeep...I was starting to wonder if I had made a horrible purchase!! So, DEFINITELY take it back to the dealer and demand a new transmission!!

My 2009 wrangler is also popping out of third gear, this has happened more than 20 times in the past two years. I have taken it back three times and they couldn't find a problem. Now my throw-out bearing are going. I had a 93 wrangler for 16 years with the original clutch and now this.

I responded in another forum to a similar issue as follows:

The 1/2 synchronizer sleeve (in which the 1/2 shift fork rides) moves towards first gear sliding over the synchro hub starting the synchronization process (synchro ring will be indexed and the cone will start picking up the cone of the first gear) Once the speed is equalized the coupler teeth will engage.. These teeth flanks have a back taper to assure positive engagement lock whilst transferring torque..
JOG (jump out of gear) can be created with following main conditions...
1) not enough spline (dogteeth) back-taper on synchro ring and coupler..(Manufacturing quality)
2) not FULL engagement during the shift cycle.. (shifting too fast or shifter boot interference)
3) the first gear has a triple cone synchronizer system and the floating synchro ring might drag too much (particularly in very cold weather..)
4) shift rail detent ball springs too weak (broken or worn out)

Everything has to be in balance to avoid "hard" shifts, (you still want to shift smoothly from 1-2 etc..) on one hand and to avoid JOG on the other hand..

The negative back taper is designed to create a lock whilst torque is transferred, as soon as you coast (reduce torque) the lock becomes less and with a bump it might do a JOG .

Just do a slow shift (be sure it is fully engaged) into first and get moving, keep a constant acceleration and maintain a slight load on the shifter towards second gear.. You will feel the "bite" from the back taper...if something is not right you will detect an easy slide out..

Bring the acceleration to almost coast and try this again..with a slight force the shifter can be moved out of first..

Just trying to give some background music..

I took it to the dealership 10 days ago and left it for the day. Unfortunately, they were unable to reproduce the problem. It happended again 2 more times this weekend. Needless to say, calling the dealership is one of my first priorities this morning.
 
#10 ·
Just curious, do you have your hand on the shifter when you are accelerating from a stop? My habit is to have my hand on the shifter most all the time, so it's on the shifter when pulling out also, in anticipation of shifting to second.

Not that I should have to but I'm trying real hard keep my hand off the shifter while pulling out and then grabbing it when it's time to shift to second. I've read other places that this seemed to be when it would happen, when the hand is on the shifter.

Either way it's not right but would maybe give a little insight. Read about a few people that had to have the transmission replaced to fix the issue.

I am quite confident that I have not accidently "pulled" it out of gear. I do tend to keep my hand on the shifter - now moreso in case I have to quickly yank it into second when merging into or crossing traffic to keep from getting in an accident.

My '07 has done this intemittantly since new. But at around 30,000km it started to do it on a regular basis. When i took it to the dealership i also was told thet they could not replicate the problem. But then a couple weeks later i get a phone call saying there is a new transmission waiting to be fitted. Took it in, they fitted the trans, i picked it up, all was fine for about 1-2 weeks. Then it started doing it again, only this time it seems worse than before, and definatly does it more often than before. So back to the dealership, they still couldnt replicate it, so i strapped a video recorder to the center console and filmed it while i was driving. The dealership now has the footage, but have no idea what is going on. They are sending the film to jeep to see what they say.

In another forum I posted the following.. (Seen the fact that you got a new tranny, you might dig into this a bit further...)

"Just tell the dealer that you don't have enough positive coupler lock in first gear.. and it needs to be fixed.. I suggest you ask him to take the outer shifter boot off then realign the inner boot assembly over the shifter bracket/sled to which it is installed..I assume that the latter are add on items by the Chrysler assembly plant in their trans dress up line..I am sure this is just a bolt-on process without any positive lock (dowels etc..) My be this needs to be replaced and/or re-aligned..

With a "healthy" set-up you should feel the positive detent engagement whilst shifting in first or any gear..

This was going to be my approach.."


The above mis-alignment can/will affect any gear..

Good Luck..

Glad you are fighting with your dealer...

...I have had this issue from Day 1. I have a 2009 rubicon unlimited, it has been to the dealer and is currently at the deal for this. They are unable to reproduce the problem. It has happened probably 60-100 times (in 7500miles), and they claim that they have never heard of this issue before (bull sh*t).

I did talk to the tranny tech and he let it slip that this is a "common manual transmission problem". Yet the dealer still will not fix the problem because they cannot induce it. I'm writing a letter to corporate, hoping that they will do something. Honestly i either want them to fix it or my money back.

You would expect after paying 30K+ for a automobile it would work right for at least the first year??? Plus this is the 5th issue i've had with mine so until they fix it, i will be negetive nancy. Other than that it is sweet!!!!

sorry for the rant! Please make sure to have the Dealer post the solution on there internal message boards!!!!

if your Jeep has been in for the issue at least three times with documented attempts being made you may possibly qualify for a lemon law resolution with the jeep, just saying.

The first important job in analyzing a JOG (Jumping Out of Gear) condition is to separate the problem into two main root cause possibilities.. (assuming proper shifting techniques are applied)
1) is it shift lever interference or bad assembly..(external)
2) is it an internal transmission issue....

I am including a pic from their parts catalog to better depict how interferences can be existing between the different boot assemblies (4-5), the shifter sled bracket (8) and its position onto the transmission case..(as referred in above post #16) Any issue here will affect full engagement travel, hence setting you up for a JOG condition..

Missing lower boot on mine!


Wow I had my boot off the other day because the plastic tabs that hold the boot to the bracket broke and I ended up drilling them all out. (looks great now instead of that old simulated plastic allen head) Continuing .. It struck me odd that the only boot there was the upper boot. I thought at that time if I designed it I would have put in an inner boot! After reading this post I realize that they did! they just didn't put it in mine! I bought my Jeep new its a 2008 and this is the first time I ever had it opened! I guess Im kinda out of luck now since its out of warranty or does anyone think I should try to get one from the dealership. Does it even matter?

Going back into the shop for the 3rd time next week. They are planning to keep it for a couple of days and hopefully dig deeper into the problem beyond driving it and being unable to reproduce the problem.

Has anyone heard more about a potential recall?

Lucky

Dealer sent me home and stuck me with the rental car bill. Did i mention it poped out on my way home!!!!

You can imagine I'm Pissed :banghead: very pissed :firedevil:

I sent a letter to corporate, salesman, General service manager and i will be trying to get in contact with the Jeep rep when they come for there quarterlty visit.

Also in the mean time i am documenting the mileage, time, date, condition of each issue (i have 3 issues they refuse to resolve). I got my jeep back on friday, it poped out 6 times this weekend.

This is really turning me off of Jeep.

Other issues include:

Navigation/Cd player turns off intermittenly
Key Fob fails to operate

anyone have these issues?

Does anyone ever get the feeling that us Jeepers are the guinea pigs, the unsavvy customers that pay big bucks for crappy quality so that savvy customers are reaping the benefits in other parts of the Chrysler market (like other models of vehicles). I think jeeps are overpriced and overall of poor quality materials/engineering (crappy stock components, practically everything could be beefed up. Perhaps that is what they know about us also: that we like to do aftermarket mods and therefore do not need to make quality jeeps if all we are going to do is take things apart right away). hmmmm :confused:

i have removed the console and the upper and lower shifter boot yesterday, and so far it has not done it since. I will put them back in one at a time and see if i can isolate the culprit. On the other hand, if it does do it in the next couple of days with the boots off, that only really leaves the gearbox itself. will post up progress for those interested
 
#32 ·
I am following a similar issue in other forums and know of two cases where the removal of the inner boot and the skid plate above the trans (under the floor control bezel) created successful results. (no JOG)

First indications are that the skid plate (#8 in earlier posted pic) is pushing the inner boot hence creating extra interference with the shift lever. (this might get compounded with inner boot stiffness/durometer in very cold weather)
I suggested to him to slot the skid plate mounting holes around the studs and retest.. I will keep you updated.. I have some of his pics and will post them as soon as he gives me permission..;)

I received a call today from the dealer, telling me they are going to order me a new transmission and shift tower. Chrsyler is aware of this issue but has not identified a root cause.

I wrote a letter, and it was elevated from the Dealer to the feild engineer responsible for the state.

I think this will be a recall in the future. I couldn't be more happy.

^ That's great. Took mine in for the problem last week, then when I get there to pick it up they said, you'll need to bring it back when we have a transmission person here! Gee ... that's what I booked the appointment for.

Anyway, I will be heading back shortly so we'll see how it goes...
