Re: Transmission Shudder

I will try this again. I have a 2011 Wrangler 3.8 w auto trans. When I try to back up there is a shutter, which I believe is the trans. Maybe the differential but I do not believe so. The more throttle I apply it will smooth out. Does the computer need to be adjusted or is it a basic mechanical problem. There is only 22,000 miles on it. Any answers anyone ?

Spent $1000 bucks to create a major problem. I took it back the next week for the shudder problem that was described. They saw that the drive shaft was leaking through the yoke and replaced the whole drive shaft. After getting on the highway noticed the problem was still there. Made the appointment to take it in this week on Tuesday morning. Made sure that i had a ride along with the service manager. He was able to duplicate it, really impossible to miss, but wanted to make sure he knew what it felt like so he could make sure it would be working before i got it back.

I have called every day this week to get updates, thumbs up their asses. They have no idea what is wrong. They applied all the software updates and still no improvements. Its pretty frustrating, researched the lemon law for GA and it doesn't cover used cars. Which i got used with 9k Miles on it two years ago. Looks like I'm stuck with this unless I trade it in.

Anyone have any fixes? i know there were some mentions of the torque converters and the transmission plates.

Re: Transmission Shudder

Thanks for the info all the way around especially about programming. Mine is different. Mine shutters when starting from a dead stop, back up a slight incline and it starts. I apply a little more pedal and it smooths out. This only happens between 0 mph and 5 mph. I was going to take it and have a tweek done on the computer to see if that solves it, I hope !!! On level or steep incline it does not do it, just on a slight incline.

Can anyone suggest a fix for both of us !!!

Talking Re: Transmission Shudder

I have an 09 GC 3.7 and have this issue as well....mine shudders as I accelerate to get on the freeway or when I am in a traffic jam and try to go from a dead stop to slow speed (0-5 mph). I have found that it also happens as I'm driving on the freeway at about 50 mph or so! So frustrating...I called the dealer and I am taking them this forum so that they cant play dumb and tell me its normal

Re: Transmission Shudder

Well, thanks for the reply on your problem . Mine is only in reverse on a slight incline. A stepper incline not a problem . Torque converter solves the steeper incline. But since I used the chip program, to change forward shifting sequence, the problem disappeared . I guess the transmission just needed as talking too !!!! All my shifts forward are as smooth as silk as the saying goes. The Intermediate gears are so in line, that on cruise control it is s real easier to drive on the freeways . I keep it out of overdrive unless I am on the freeway and I see there is smooth sailing ahead . In very slow bumper to bumper I shift manually. Of course I have headers , a cat back duel exhaust and a different cold sir intake as well, which makes all the difference in the world. I also had installed a larger master cylinder to stop on a dime . I did that because I frequently pull trailers . 3500 lbs. so that is handy dandy !!! For my purposes it is now outfitted just right. It is set up for s lot if city driving . I am not a stump jumper. I go to Lake Tahoe frequent so the 4X4 is suited quite well for the snow . With the headers, the exhaust, the reprogrammed engine and transmission and the air intake, I just have to be careful of the torque in the snow . All that crap adds a considerable amount of HP and torque. It is the torque that is squirrelie!

Sorry I went on but maybe you or someone else would be interested in the information .

Re: Transmission Shudder

Mine was only at 0 - 5 MPH in reverse at a slight incline. Other than that all the intern gears and forward gears are functioning properly. Thanks for the input !!!!!

Re: Transmission Shudder

My 2011 JGC overland has been in the shop for 3 weeks this time. And 3 weeks on and off in the past with no progress. I finally got jeep corporate involved with this run. They have sent engineers and consultants down to troubleshoot the issue. They are replacing the rear differential on Tuesday. We will see what happens.

Re: Transmission Shudder

Good luck! I hope something positive comes from this and the problem is located so others later on can not have to go these hoops! Thanks for taking the time to be persistent and getting something done instead of the usual "there is nothing wrong" , "that is the way it is supposed to be", or the"I don't know"!!!!!! It seems from other threads I read that Jeep / Chrysler passes the buck and don't want to back their product . I am very fortunate to have used the CHIP reprogramming to have the transmission readjust itself by this method. Ever since reprogramming the transmission it works like a champ ! A whole lot better than when I bought it used with 20 K on it. It runs so smooth now. Reprogramming it to shift at higher RPM's , just an extra 500 , nothing damaging to the engine or transmission. I also learned a lot about the 5 - 20 oil makes sense now. It seems the tolerances are so tight that it takes that weight for all the moving parts feet the oil it needs. A higher engine oil weight will not get oil into these parts , the self adjusting parts like the valves, cam, the lifters just as an example. My personal mechanic, not Jeep, says it is important to let the engine warm up before driving so these adjustments can be accomplished. I certainly can tell if I don't wait an extra minute or two. I can hear the valves working differently . Just an extra bit of info .

Re: Transmission Shudder

My 2012 Limited 5.7 had the 40-60 mph shudder. It was intermittent but very annoying when it did occur. On several trips to the dealer, it either wouldn't shudder at all or minimally, so I got the "that's normal" excuse.
I had the PCM reprogram Service Bulletin 18-035-14 done last week, and the shudder is gone. Just hope it stays fixed.
Now I finally like my Jeep. My only complaint is that it took almost 3 years to address this issue.
