Flash: Torque Converter Shudder / Shift Quality Improvements / DTC P0732

OVERVIEW:
This bulletin involves reprogramming the Powertrain Control Module (PCM) with new software and replacing the torque converter as required.

SYMPTOM/CONDITION:
The vehicle operator may experience one or more of the following symptoms:

1. Transmission Shudder – 42RLE All, 41TE CS/JS, 62TE CS/JS
a. This condition can only occur after the vehicle has been driven and the torque convertor is past the break in period. Torque Converter break in can be confirmed with the StarSCAN®.
b. If experienced, the shudder may occur when the transmission temperature is between 38° C and 54° C (100° F and 130° F) during steady state driving with the torque convertor in partial lock (EMCC) operation. The shudder feels like the vehicle
is being driven over rumble strips.
2. Torque Converter Pull In Bump – 41TE JS, 62TE CS/JS
a. This condition can occur due to abrupt torque converter clutch engagement during EMCC initialization.
3. DTC P0732 – Gear Ratio Error in 2nd Gear – 62TE CS
a. The MIL may or may not be lit (2 trip fault).
b. Limp In will occur when this fault is set.
c. This is an intermittent condition and cannot be duplicated. If the fault can be duplicated, other conditions exist and further investigation will be required.
4. Shift Quality Improvements – 62TE CS
a. Rapid Decel Coastdown Stumble.
b. Low Speed 3-2 Kickdown Harshness.
c. 4-5 and/or 5-6 upshift flare bump.

  1. THANKS FOR THE TSB. I KNEW SOMETHING WASNT RIGHT, IT OCCURS WHEN I’M GOING ABOUT 40 MPH AND THE RPMS ARE ABOUT 1400. IT FEELS EXACTLY LIKE STATED LIKE I’M DRIVING OVER RUMBLE STRIPS. TAKEN HER IN MONDAY.

  2. Does anyone know if the torque converter has to be replaced? Or can they just run the flash? My understanding is that the torque converters are all on back order.

  3. Mine was built Jan 26, I think. I still haven’t took delivery as it is in route on a train. Do you think mine has the (FIX)? or will I have to take it back to the dealer???

  4. MAN I THOUGHT IT WAS THE ROAD …LOL I KEPT FEELING THIS …AND THOUGHT IT WAS THE ROAD, WELL I WENT OVER SOME FRESH PAVED ROADWAY AND FELT IT REAL BAD AND THOUGHT ….DAMN WE PAID TAXES TO HAVE THIS ROAD REPAVED LIKE THIS AND I WAS GONNA CALL THE FLORIDA DOT….LOL I AM GLAD I READ THIS…HA!

  5. Funny thing. Just bought an 03 Liberty and had this problem. However after changing the torque converter , and a complete overhaul on the tranny, the problem with shifting patterns remained. Today, got the call that they are replacing the whole transmission. I have only had the truck a month and it has been in for this problem, going on the third week. I have only driven the truck for 9 days. At least I am getting a new transmission.

  6. How do you find out the date of manufacture and the “sales codes”? Would like to know if my 07 Rubicon is affected. I don’t know the transmission type either. Any help?

  7. Had this TSB fix done last week. Completely resolved the issue and mad a noticeable difference in the way the Jeep’s transmission shifts.

  8. I took my 07 Rubicon into the dealer with a shudder occurring going from 1rst to 2nd. I have the 42RLE trani with a build date of jan 07. Also a leak from my freedom top. They called back saying they could not find a leak and after driving 100 feet in their lot decided they could not find a shudder and there was nothing to fix. This is the first and last time I ever go to Jeep Carlsbad, CA. Those guys are a joke. They said wait till I have 5k on it and bring it back. I may bring it back every 100 miles if it keeps doing this. Suggestions?

  9. Rick,

    The shudder that I had is when Jeep is going about 40mph and most of the time in the last gear (overdrive). As mentioned, this TSB reolved the issue. Have not heard of the problem you mention between 1st and second. I would recommend making an appointment and taking the service manager/tech for a ride so that you can point out the problem. With regards to them not finding your leak, did they confirm they followed the instructions in the TSB that exists for the Freedom top water leaks? I belive it mentions that have to run water over it for 5 minutes or so.

  11. **** SHUTTERING ****

    Yes, my Jeep Liberty 2007 has had this problem with TWO torque converters replaced (see DTC P0732)–still needing a third torque converter or new transmission. Problems started at 700 miles on the odometer–filed under the Florida Lemon Law and the arbitration panel found for the owner. This problem seems to thread not only Jeep Liberty but other Chrysler products with the same transmission. Any shuddering take it in to the dealer and make them fix it–they are aware of the problem even if they play dumb saying “this the first one like this that we have had in the shop”!

    No excuse for an American made car and I’m disappointed in the way Chrysler handled this–they now own a 2007 Jeep liberty that has “lemon” attached to the title–good luck to all!

  12. On my previous post for the 2007 Jeep Liberty–please note that should be “shuddering” or “shudder” and not shutter–my former English teacher would be appalled!

  13. Dealership denies this TSB applies to my Wrangler built 2/07. Anyone else experiencing a shudder on a cold shift between 1st and 2nd gear? The local dealer stated this is normal (torque converter reduction) they called it to improve fuel economy.

  14. My 07 JK is doing exactly what Eric describes…..a shudder on a cold shift between 1st and 2nd. It’s a little unnerving, but I haven’t taken it in or anything.

  15. Took mine in on Thursday and the dealership have ordered parts and I return the jeep 01/22 to have it completed will advise of the outcome.

  16. I think that I have this problem, but it’s a 08 built sometime in the month of October it should not have this problem. I was just wondering if any other people with 08s are having this problem.

  17. My 07 wrangler is doing the shuddering with a cold shift from 1st to 2nd gear. It also grinds a bit going into second when the jeep is cold. Clutch is pushed to the floor. Any help on this? I took it to the dealer and they said they couldnt make it grind….What should I do? Grind and shuddering related? 11k miles

  18. Got my 2007 back from the dealership after the TSB was performed and it is noticable just how bad the situation was (decel stumbledown poor shift quality and lack of pick up). The dealership took 2 days to complete (TSB states 5-8 hrs) but it does appear to have improved shift quality and performance considerably.

  19. I have a 2008 JK 4dr Sahara and believe this is happening. I first noticed it after I went off roading for the first time and thought it might be some dried mud throwing off balance in the wheels, but after a good cleaning, I am still experiencing it.

    I feel the shutter sometimes while driving at different speeds, AND most noticably sitting at red lights as the whole thing (especially steering wheel and dash) will start to shutter, last 30 seconds or so, and go away.

    I’ll be taking it in soon and tell them it wasn’t limited to 2007 models.

    Has anyone else experienced this on a 2008?

  20. i have a wrangler rubicon 4 door automatic transmission 2008 and would like to no if someone els has experiensed a shuder in reversing on a steep incline ?

  21. I HAVE A2008 JEEP WRANGLER; AT SLOW SPEEDS THE TRANNY SHUTTERS. VERY ANNOYING WHEN A 5100 MILE VEHICLE HAS TRANNY PROBLEMS. WHAT COULD IT BE.

  22. I have a 2008 JK Unlimited and I blew a trans. solenoid at 3074 miles. When I got it back from the dealer 2 days later it now has a very rough idle sometimes and the service manager tried to tell me it’s normal…….

  23. I HAVE A 2008 LIBERTY WHICH HAS THE SAME SHUDDER PROBLEMS I CONTINUE TO READ ABOUT. THE DEALER PUT A NEW TORQUE CONVERTER IN AND SOFTWARE UPGRADE BUT NO CHANGE.THEY ARE CLAIMING IT IS OK. I AM SO UPSET WITH IT I FEEL LIKE HAVING A PARTY AND CHARGING PEOPLE A AFEW DOLLARS TO SMASH THE HELL OUT OF IT RIGHT IN FRONT OF THE DEALER SHIP.

  24. I have a 2008 Liberty in the shop now replacing the torque convertor, because of the shuddering. Did replacing the torque convertor fix the problem for anyone else?

  25. This describes the problems I’m having. However, I have a 2007 Grand Cherokee and it doesn’t appear to be covered by this TSB. Also the “pull in bump” occurs while in reverse the first thing in the morning.

  26. I have a 2009 Wrangler JK and it shudders very noticeably when I back up an incline, especially if I have passengers in the car. The dealer says that it is a known problem with 42RLE transmission and that they are working on a fix. Said the car is safe to drive, but it sure doesn’t feel like it. Any thoughts?

  27. I was able to get my torque converter replaced, but it did not fix the problem. I went to another dealer and he found the number 2 cycinder was misfiring due to a bad plug wire. Shudder gone. Mine is a 2009 with 9500 miles. Very relieved. My symtons were identical to the common problem description given by others. Good luck with yours

  28. I have a 2009 4 door JK and I’m now on my 4th torque converter. Yeah, you read that right, 4!!! I’m still no confident that this was “the charm”. I’m bringing it to a different dealership if it happens again. I’ll post again with any new info….

  29. my 06′ jeep wrangler shudders,cruising 40 mph and above.sometimes not for a week or two,then all of a sudden it’ll do it a couple of times in a week.Feels like the steering or a wheels gonna fall off,then when I pull over and start over it stops like nothings wrong with it.Sucks having to pull over in heavy Traffic,sometimes across a couple Lanes.Had it inspected,they said a Tierod was bad,they replaced it and I have the same problem.Now I read all this with other Jeeps.Sounds Like Jeep is trying to get out of a massive recall.They should stop ducking this issue.

  30. I have a 2008 Jeep Liberty. I have a 35 minute commute to work. Typically the transmission shifts from 1 to 4 about 8-10 times per way. Around the 8th time, the shift from 1-2 becomes very hard and sudden but the other shifts are still incredibly smooth (to the point I can barely feel them). So, I’m thinking this is not the transmission but the torque converter? I have had this since April 2008 and have had this problem intermittent but seems to be more defined now. Any ideas? Dealership says this is normal and on another occasion said it was reproduceable. BTW just hit 40,000 miles today.

  31. I have an 08′ Wrangler Sahara 4 door. I’ll be replacing the Torque converter with a performance torque converter. Hope this fixes it, it’s the only fix I’ve found for this problem for shuddering at slower speeds… (Via internet forums)

  32. I have a 2011 jeep liberty kk. 6 times in 2 dealers, they start with balancing tires, then replacing shocks, then that’s normal! that’s the a/c cicle. Lol that was funny. turn ac of, off course is there. so another dealer. torque converter cluch engaging valve, blabla same problem. ok.. again. dealer. learning mode. again dealer…. ready for replace parts according to Chrysler customer service. but according to the dealer. they are going to diagnose what the problem is. and take it to a ride. OMG. after they find the problem. they do a step back? right now my liberty is in the dealer. 35k miles and bouth CPO a month ago.. so all this in 1 month. it shudders and feels like im towing a heavy trailer, at 45, 50,60,65 even at 80.

  33. dealer replaced. tc, pump, seal, and oil. same problem. jeep liberty kk. 2011. the shudder is there.

  34. I just started noticing a shuddering/vibration when transmission (auto) shifts into 4th gear. Found TSB from 2007 mentioning similar issue. Took to dealer and they tell me they never seen or heard of issue. Were not real interested in helping me with problem. Any advice on who and how to get problem looked at and hopefully resolved?

  35. Hello

  36. hey guys iv got a 2008 jeep wrangler unlimited x its lifted and has larger tires on it and ivbeen having problems with the transmission fluid getting burnt or turning black iv changed fitler and flushed trany plus added an external trany cooler but the fluid still turns black within 5000 miles.. it shifts fine has good getup and go. the only thing is when it getinto the wind it acts like over drive comes ot of lock up and runs at around 1800 rpms. any suggestion would be great thanks..
