A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module (PCM) to correct this concern.

    I noticed the 'shudder' described here and brought it in to the dealer and told them of this noise. On first visit dealer could not find a problem. After driving some more I detected that this 'shudder' occurred in the 40-50 mile range and brought the car back to the dealer. After two rides in MDX 2nd mechanic finally correctly diagnosed the problem ( one would think that this would be the first thing they should suspect). When paying $1800 repair bill ( that's with 'discount') I complained that the internet had numerous complaints about torrque converter problem and that quite a few customers did not pay for this defect repair. I also voiced my concern over possible future transmission problems. The manager disregarded the numerous internet documentations and claimed the model had no transmission issues. Months later I was at my local mechanics shop with another car & I described the MDX 'shudder' and he immediately told me that it was a torque converter without my telling him anymore. I was not happy with the stonewalling or lack of knowledge that Acura showed in dealing with me. I'd prefer to have my car serviced by Acura however this kind of treatment has driven me away.

    Shuddering usually between 25-40 mph when slightly depressing gas pedal, cruising or slightly accelerating. Shuddering stops when letting off the gas pedal or by de-pressing to accelerate quickly. I called the Acura dealership and my vehicle did not have a recall for a Powertrain Control Module (PCM) software update to resolve issue. Acura technician mentioned it could be the torque converter or another software update needed.

    It shudders or vibrates from time to time. Dealer changed the tranny fluid and it would go away for a little while. I think there should be a recall for the transmission.

    After recent software upgrade for the transmission recall, I am experiencing noise and shudder after car reaches 40 + ml/hour. The noise is disappearing after 75 + ml/hour.

    Have the same shutter / washboard sensation when driving at city speeds. This just started last week. We have owned since new and have religiously maintaned the car at Ron Tonkin Acura. Very dissapointing as we researched reliability at the time of purchase and the MDX was highly rated. I will report back when we have a diagnosis and repair. Have read other threads, stating this is a safety issue as the drive wheels (front) can all of a sudden lock up and not spin while driving car. If this happens on a freeway, imagine what would happen.

    Exactly the same complaint. 35 to 40 miles an hour. Shudder or Vibration. Started doing it following a transmission fluid change.

    It was noted at the time of the fluid change approx. 300 miles ago that there was a accumulation of metal shavings on the magnet attached to the transmission drain plug

    From the looks of these complaints, a T converter looks to be in the near future. Currently not driving the car for fear of collateral damage if the converter were to come apart.

    In my opinion, Honda/Acura should provide the parts for this failure. They certainly have been made aware of it from the looks of the numerous complaints!! In my opinion they should have recourse on the vendor.
