it is your torque converter. it not only causes the "hesitation while trying to pick a gear but also a "growl" under the hood. sorry- but before you pay 1000's, try winns stop shudder. maybe and good luck
i also had a vibration in my car. Turns out it was the Torque converter. This is a common problem with acura mdx's.
I had the same problem and was told it was about $2,400 for the repair. I was also told that if I did not seek to make the repair, the problem would not damage the car, but would become louder over the next few years.
The repair involves removing the transmission system, rebalancing wheels and quite a bit more.
I asked if the factory could help and received assistance from them - it brought the cost down quite a bit. Since this is a common problem you may be able to get help. My MDX was a 2005 model.
Just picked up my 2005 MDX from dealer after replacing the torque converter. It appears that the vibration/grinding between 35-40 mph has now been eliminated. For background, I reported this problem in March 2009, a couple of months prior to the expiration of my warranty. The service tech stated that he/she could not reproduce the noise I was hearing. Over a year later, the noise was now continuous. I took the vehicle in and this time the service tech could hear the noise. I was told that the vehicle was out of warranty (45,000 miles, but over 60 months) and that it would cost $2,000 to $3,000 to fix the problem. I opened up a case file with Honda America. After several calls, I was offered a repair for $500. I continued to complain and mentioned that I had uncovered over 100 complaints for the exact same issue. The Honda rep. still would not budge on the $500 cost to me. Finally, I mentioned that I might pursue a "class action suit". He said he would speak to the district supervisor. Miraculously, he came back and said that Honda America could cover 100% of the repair. I would suggest that anyone battling this issue out with Honda America mention "class action suit". There attitude seems to change quite significantly! Good luck!
Could be an out of balance tire/rim or a driveshaft. I would have all the wheel checked first then go from there.
I have a 2003 MDX with the same problem. However, If I drive in "4" rather than "5" when driving at speeds like that (mostly in-town) I have never heard the sound. When I get on the highway I shift it up to "5" ...I have been driving it like that for over a year and have had zero issues!... try this out before spending 1,000's... when I have the money I will eventually repair the problem. I have also had my transmission flushed and refilled with Honda fluid just in case there were any metal shavings that got into tranny. Good Luck!
I have the same problem with my 2003 mdx. if I drive in 4 rather than 5 at low speed around 40 to 50 I don't hear the rattling sound.
You need to take your MDX back to the dealer and have them do the update that corrects the "stuttering" occuring in the transmission. This is a known problem and they will fix it for free.
