Own a 2004 Acura MDX (85K miles) that I just bought the other day and I noticed on driving it home from dealership an intermittent - what almost sounded like gear grinding. Is that possibly the "shuttering" you describe? I went back to dealership service and took the technician for a spin so that he could hear the noise. After 15 minutes of driving, he heard it loud and clear. The sound comes and goes unpredictably but seems to occur most in the 42-50MPH range - without any dramatic RPM changes. Technician checked and then replaced the differential fluid and said it could be "sticking", ie. causing the noise. The advice he gave was to drive it for a few weeks and it should lessen and eventually go away. What do you think? Is this unrelated to the torque converter slippage?

Did the gear grinding go away?

It has NOT. How long should it take to go away? But then again, I haven't driven the car that much since they replaced the differential fluid - they said to give it a week or two.

Since the grinding didn't go away, I took my MDX to one Acura Dealer to have them assess whether it was a torque converter problem and they said it was the transmission AND the torque converter that were the problem. YIKES. I told them I wanted a second opinion so took it to a different Acura dealer who told me it was just the torque converter. This 2nd Acura dealer still has the car as I try to decide what to do. Obviously, I don't want to get the transmission replaced if it doesn't need it but I don't know what questions to ask related to the diagnosis. Anyone have any suggestions?

Yes....Its definately your torque converter. If you havent taken the time to do so... do a search on the internet regarding MDX and bad Torques. Its extremely common and frustrating. I have a 2006 MDX that has 70,000 miles on it...
Mine started rumbling and grinding at the same speeds when I had about 62,000 miles on it. It was still under the powertrain warranty... so it was replaced no cost. The car drove like a dream after it was fixed, so that is how I know that was what it was. WELL...Here I am...not even 10,000 miles later... not even a complete year...and it has started AGAIN!!! Same sound... same problem. I have read in different post of people getting 2 or 3 new torque converters... why dont they replace them with a brand they know isnt faulty?!!! Now my car is out of warranty...but I plan to take it back and demand a new one. THe problem with this noise it getting it to reoccurr when they are driving with you in the car...and since mine has Just started doing it again... it will be hard to point out.
Replacing the torque will cost you less than replacing the Transmission...so I would start with that...because I believe that is where the problem lies.

Thank you and I am sorry to hear about the recurrence of the problem with the new torque converter. For what it's worth, I was worried about them not hearing the noise too, so I told the technician that we were going to drive together until he heard the problem. I asked that they schedule a time when he had at least a half hour to drive with me. We drove for about 20 minutes and the grinding noise occurred as we were driving up the street back to the dealership. Good luck.
#12 of 89 2005 MDX Transmission Vibration @ 35 mph
Jun 26, 2010 (5:44 am)
Starting around 30,000 miles, I began to notice a vibration/grinding noise while accelerating through 35 to 40 mph. The noise would last for 10 to 15 seconds and then stop. I took my MDX into my Acura dealer at 35,000 miles while it was under warranty and they said they could not reproduce the problem. The problem continued to worsen however I was now out of warranty. I did some research on the internet and found 14 reports of the exact same problem on the NHTSA (www.hntsa.gov). Out of 30 total complaints, 14 were this specific transmission problem. I also found a 2004 MDX service bulletin (#6003; NHTSA # 10022468) that states "Torque converter shudder or vibration between 35 and 40 mph". I presented this info to the Acura dealer and they acknowledged the problem and agreed to pay for 75% of the torque converter replacement (the care is 6 years old and has 45,000 miles). Why hasn't someone started a class action law suit regarding this problem given the significant amount of data pointing to a general problem?

My 2001 MDX, while the AC is on, begins idling (engine runs hard) when I am at stop lights. I turn of the AC and it stops. Anyone ever experience similar problems? What could it be?
#14 of 89 06 MDX Torque Converter
Jun 30, 2010 (4:07 pm)
I have an 06 MDX had the torque converter replaced in Dec 09, June 30th,2010 back in for same problem. Dealer is telling me that Honda will do one of three things replace torque converter again, replace tranny or nothing until they have a for sure fix, evidentally replacing those things hasn't cured the problem in some cars..I am so frustrated don't know what to think, does anyone have any ideas or have heard of such a thing? Should I hire an atttorney?
