Thanks to all for posting problems and solutions on this site. I have a 2007 Honda Odyssey that I have been fairly satisfied with. Current mileage is 36000. For the past 6000 miles or so I've been experiencing a vibration/shudder at 40-45 mph, observing engine rpms fluctuate from 1300-1600 associated with shifting into 5th gear. I have also noticed what felt like an intermittent misfire feeling at cruise speeds. I noticed this more during cold weather, more when the car was cold and more when I had the whole family in the van (600# of people). At 40-45 the problem was regularly intermittent with variations in engine rpm and an engine lugging sound (and associated vibration). Also, the best way of reproducing the problem seemed to be to get it into the sweet spot (40-45mph/1300-1500rpm) and come to a slight incline in the road requiring almost a breath of increase in the accelerator. On my initial complaint to the dealer I got the "normal condition" line. Doesn't work with me, I test aircraft for a living and know the difference between normal and "interesting". After the first visit I did my internet research, worked on defining the problem and developed my strategy for the next visit. 1st, I needed a dealer who could hook up a computer to take a snapshot during the shudder behavior. 2nd I needed a dealership technician who had seen the problem before (very important). I found both at Scholfield East Honda in Wichita, KS. The technician, who had experienced two Odyssey's with the same condition in the past, was able to reproduce the problem, take the snapshot and send it to Honda. The solution was to replace the torque converter. The repair took two days, the torque converter was replaced, the engine computer was updated, they cleaned out the transmission cooler lines (I have a towing package) and performed an alignment all on warranty. I picked up the van this evening and it drives "properly" again. Hope this helps. I would definitely shop for a Honda dealer that has seen this problem before. Search out a technician who knows how to reproduce the problem. Thanks again, |

My original post was #83...after my mechanic has replaced the motor mount, which they said was broken. Done. They replaced the Y in the exhaust as described on the Honda Bulletin. Done, yet the noise remained. $1500 later... The mechanic transported it to Honda and a brilliant mechanic there solved the problem. They determined the "serpentine belt auto tensioner" needed to be replaced, Done and the vibration due to the RPMs is gone. I believe that if you take yours in they will need to do all 3 things to make it right, but you might be able to get away with just the serpentine belt auto tensioner for now. Good luck to you all and I am thrilled to have my Honda running with the same hummm as when I bout it in '07.

New service bulletin from Honda. After two years of aggravation maybe I can finally get my van fixed. A judder from the torque converter lock-up clutch may be felt while driving between 20–45 mph. To minimize the judder, a PCM A/T software update is available. If the judder returns sometime in the future, after the PCM A/T software is updated, the torque converter would need to be replaced. A09-053

Replying to: ee4life (Jul 21, 2009 3:34 pm) to a different RPM to help mask the symptoms until vehicles are out of warranty. As ee4life stated his is not 100% corrected. I beleive the bulletin stated some torque converters will still have to be replaced. Recalibration will probabilly not correct the problem but just make it more liveable at the current time. My odyssey has had the shudder since five thousand miles. How much has the shudder damaged other transmission components and or engine mounts. Especially on higher mileage vehicles. Good luck to all.

Replying to: ddssjsk (Jul 21, 2009 3:59 pm) I always thought it wasn't normal, but the dealer blamed it on the VCM and ECO function and no TSB was available at the time. Then the TSB finally came out and it is now being addressed. This was handled in the same fashion as the soft brakes TSB. We experience the issue...we complain to the dealer....they say it is normal or are "unable to reproduce the issue" and we wait until a TSB is issued. It would be nice to have Honda acknowledge the issue in a tech line summary article or service news article while they are working on the fix and TSB, so that we can at least know it is indeed an issue and that a fix is coming. I have seen them do things like this before on other issues....why not ours? Please post your thoughts after getting the update. |

After considerable research, we found that the chip that manages when the transmission shifts was not set to shift at the correct speed...a manufacturing error. Once that was identified, our local Honda Service Manager reasearched it on his own, get the "new" chip & fixed the problem.

Replying to: craig1970 (Jul 22, 2009 1:19 pm) I have been looking all over the internet for a TSB concerning this problem in the 07 but unable to find it. My dealership is absolutely refusing to replace the torch convertor. Can anyone point me towards a TSB for this. ALso, my problem starting when I reached around 20k miles. They dealership originally said it was my fuel injections and I paid $150 to have them cleaned and this didnt work. I picked up the van yesterday after the software update and it lurched on me and I turned it back around and they have it again. Please help!
