Unknown Transmission Trouble :(

So apparently I have stumped the techs at my dealer and Chrysler. I had a check engine light come on and set up an appointment to get it looked at. Well it decided to go off right before I was scheduled to get it looked at. They said they could do anything since the light had gone out. I told them I was also having a problem where when I would get to about 35-40MPH the jeep would hesitate shifting at that point. So me and the service manager took it for a road test so he could see what I meant. Well this was Monday, I get a loaner and head off to work. I get a call later saying they ran some test and not sure what is causing it and they contacted Chrysler for some help. I call them later on see about an update. They did some tests and sent the info to Chrysler waiting for a response. Tuesday comes and I go to work and await to here what is wrong. I call them and see what is going on. Apparently some of the valves aren't performing up to spec and they are trying some more tests from Chrysler. Luckily I get some days off for the Thanksgiving holiday so I don't have to worry about work. I get a call today saying they are still looking at the valves and solenoids and sent a bunch more info to Chrysler. They asked me if I need my vehicle. I say of course but I want it fixed. He mentioned that possibly they may need to put a new transmission in. But they are waiting to see what Chrysler says about all the info from thet test they just did.


It's a 2012 Wrangler unlimited. The only bright side is at least i got another jeep as a loaner, though it's a patriot.

So anyone else have problems with there jeep hesitating when it shifts at higher speeds?

They called back again a little later and got authorization to replace the Valve body. Hopefully all will be well afterwards.

I had a very similar dealer issue with my 2012 sport. The transmission hesitated when shifting from park to reverse or drive. They first tried the valve deal, didn't work. Tried something with torque converter, didn't work. Replaced entire transmission, didn't work. Finally figured out all that was needed was an adjustment within the shift system/linkage or something, supposedly good to go now.

But anyway. Each time they "attempted" to fix it, they had to call big brother Chrysler and have them figure out what they should do. Its a terrible process. Each time it took over a week to get anything done, nobody knows whats going on because someone else is making the decisions for them, no call backs. Went and picked it up multiple times only to find that the issue wanst fixed, or something new had come up that needed to be addressed. All in all it was at the shop for about 2 months. Pretty convinced that Chrysler/Jeep techs are completely incompetent at this point, at least at my local dealer.

Hopefully your situation gets resolved sooner, but I would suggest staying on them daily. It seems they have no incentive to get anything done otherwise.

Also, they acted like my situation was the first time anyone had ever seen anything like this. Sounds like you are getting a similar story

A typical canned response.

Guess they aren't allowed to do anything without checking in with Big Brother. Sucks because then they need to wait for each response before trying something new. And it being a holiday week, I can imagine responses are even slower do to people taking time off. I should have it Friday night so hopefully all will be back to normal. *crosses fingers* Course I will need to put it back in for the recall when they finally get the part. Hopefully after that it will be only be in for routine maintenance.

Happy Thanksgiving all.

Well it seems the Valve body replacement wasn't the fix. It is a bit better they said but still not corrected. They did more tweaks and adjustments. Now they need to pull the transmission and break it down to check a seal inside. Ugh. Maybe next week. I have a feeling I'm going to go through what cswerner went thru with his.

So it's been over a week and half and the Jeep is still in the shop. They can't seem to pinpoint the problem. They've replaced the Valve body, pulled apart the transmission and replaced some seals. It still isn't shifting correctly. From talking with the service manager, an engineer will probably get involved now. I just want my Jeep back, I miss driving it.

The order of events sounds like Chrysler will not allow a dealer to perform warranty work without first talking with them. I'm willing to bet they are not stumped, just that Chrysler is telling the techs to try the cheaper "fixes" first.

It's a sad day in the auto repair industry when the manufacturer ties the hands of the techs and service writers that can probably tell you right off the bat what the most common fix is for these items.

And now they are placed an order for a Bulkhead retainer. Unfortunately the part is on back order from Chrysler. They don't have an ETA on when there will be more. I'm at the top of the list when they come in. I have a strange feeling this isn't going to correct the problem either. Maybe if I'm real good till Christmas, Santa will bring me my Jeep back.

So I have a friend with a 2013 sport automatic with what seems to be the same problem. He sails he gets in the highway or goes to accelerate and the jeep hesitates. RPMs go up the jeep doesn't go anywhere. He pulls over out it in park shuts it off and on and then it works. It's happened about 6 times already. Dealer couldn't find anything wrong. I told him I would search the forums for info. Is this the same situation you guys are experiencing? It's intermittent and as of now there is no correlations with heat, cold, rain or sun. It happens when it wants to happen.

In my case it is when I get to the 30-40 MPH range that when it goes it shift it hesitates and you get a sling shot effect. I've also had it occasionally do nothing when I shifted into reverse and all it would do was rev the engine instead of moving. The first part happened consistently, the reverse thing only about 2 or 3 times.

Too bad they won't do the decent thing and swap the whole transmission. Just curious are you running stock tires size?

Wow, I thought these transmissions were stout problem free units. Honestly I heard they were very good and problem free. I hope they sort it out for you!

I don't know anything about the new 5 speed auto, but is the ECU that controls the transmission actually part of the trans itself, or integrated into the rest of the vehicle computer?

It seems like instead of replacing the transmission piece-by-piece, it'd be worth a shot to try swapping the module that controls the whole thing. If that is fine, you put the original back in and move on to the mechanical rebuild.

I wouldn't even want them pulling it apart until the light came back on, I wouldn't trust them not to screw something else up shotgunning an issue they can't find.

I wish there was I way they could look into my service record or something. After whatever adjustment they did last I have not had any issue. From what everyone is saying very similar symptoms.

May I ask, did you happen to increase the tire size without correcting the speedo and shift points via procal or flashcal? I'm wondering if that may have some effect on the transmission performance.

So it looks like the part will be in this Friday. Hopefully this will fix the problem. On a positive note, the part for the recall came in. So they can put it in while it's there without me having to drop it off again. Hehe. I miss my ride.

Well they got the bulkhead retainer in yesterday and put it in today and tested it and it still doesn't shift smoothly. At this point they have pretty much rebuilt the transmission. So they contacted Chrysler again and it has been escalated to a higher up engineer at Detroit. The "good" news is that since it has been escalated they should get responses sooner. I want my Jeep back so much, but at this rate it doesn't look good. I contacted a Lemon Law lawyer to see what my options are if they can't get it corrected. I miss waving to other Wranglers. Maybe a 2014 is in my future.

The 5spds are indeed stout units but if there's one weakness that is easily suffered it is water moisture in the fluid. The 5spd Mercedes units develop significant shifting/driving issues when a very small amount of water (forget the %) finds its way into the fluid. I'd recommend multiple pan-drop fluid replacements. Do not do a flush with the 5spd as flushing has been known to damage the internal seals in these particular units.

I might add to the OP: if they essentialy rebuilt the trans already, I hope they didn't cheap out and re-use the old fluid. Dealers may do that when nobody's looking.

Well I stopped by the dealer to get an update. They just got authorization from Chrysler to put a new transmission in. Though with the holidays coming up it won't be down before Christmas. Hopefully this will solve the problem and I'll be back in and waving to my fellow Jeepers by the new year. Hopefully there are putting new fluid in with each step.

Well I finally got it back from the dealer. After replacing the transmission it seems good as new. I guess the good part out of it is I got a free inspection out of it since mine is due next month. I also got the recall done while it was there. So *knock on wood* I should be good for a long time. I must say that as soon I as i got in it I had a huge grin back on my face. Felt almost like I was getting it for the first time again.

Merry Christmas and Happy Holidays everyone.
