#61 of 1820 Re Wind Noise by danny30 Jan 09, 2003 (6:18 am)
just got my 03 base with sage brush. Looks great, drove a little bit, over 70 mph on high way without any noise.
#62 of 1820 transmission not so smooth by danseo Jan 09, 2003 (8:23 am)
i just bought '03mdx with touring pkg. my first time buying an acura. i read great reviews about mdx. so far everything else is good except gear change happens above 3000rpm if i need to drive normal. is this the norm with all the acura cars? acceleration is not so great. has anyone else felt the same with your mdx?

I don't notice that problem in my '02, they are different transmissions though.   Acceleration is good in the '02.

Have 02. Engine speed is very low on freeways and the engine doesn't have enough power to maintain speeds on inclines without either a transmission downshift or at least unlocking the torque converter.   In my case engine speed is 2100 to 2300 rpm in 5th gear at freeway speeds around here. On most inclines the torque converter unlocks and rpm jumps as much as 500 rpm, but it is not felt or heard in the car. The steeper hills result in an actual downshift to fourth which is felt and heard as the rpm goes to 3000 or more.   The gear ratios are about the same on the 03 and the 03 weighs a little more than the 02. Engine torque at low rpm is essentially the same for the new engine. From time to time, especially on hills, I would expect the new transmission will behave about the same as the one in my 02.   The tall overdrive gear ratios on the MDX do not make for peppy fifth (or even fourth) gear acceleration. Mine will go to the car's governed maximum speed in third gear, so even third could be shorter for better passing performance. Peppy performance, at freeway speeds, requires aggressive gas pedal use. High speed two lane road passing takes lots of space and planning.   Acceleration performance of my 02 is actually better around town than I expected and about as expected on freeways.
#65 of 1820 Clunking sound out of rear tranny by lmsylvan Jan 10, 2003 (3:12 pm)
I'm new to this group. I've had my 02 touring MDX since June, and it's going in for its 7500 mile service on Tuesday. Over the past month or so, I've heard an audible clunking sound at low speeds. Not sure what the pattern is - changing gears, etc. But, is this the same tranny problem discussed on this group? What should I keep an eye out for with the service dept (Mile High Acura in Denver)? Is there a solution? Seems like a loud noise for a 40K vehicle. Thanks

The rear brakes clunk, bang, or thunk on mine the first forward stop after backing up. 7500 mile service is essentially an engine oil and filter change as well as a rear axle (VTM4) fluid change.
#67 of 1820 rear clunk by lmsylvan Jan 10, 2003 (5:01 pm)
so, can they do anything about the clunk, does it go away? what did they say when you mentioned it to their service? will this be a big maintenance issue with brakes, something else?
#68 of 1820 clunk by fndlyfmrflyr Jan 10, 2003 (6:30 pm)
I haven't asked the dealer to fix the noise. My selling dealer has a hard enough time getting the easy routine stuff done right. Last time in they dented the car door while they took four hours to do a ten minute job - and did the job wrong.   I'll take the car into a different dealer's shop in a few weeks and see if they can get rid of the brake noise. Unfortunately, the next nearest dealer is operated by the by the same people as my selling dealer.

The are also supposed to re-torque the suspension bolts on the vehicle. Perhaps that is your issue. A few other things...there is no transmission problem with the MDX (at least not yet) that we are all discussing. Some concern over a web article talking about 1-2% of FWD Honda's with a similar transmission having a potential issue. At very low speeds the rear transmission is not doing much, so maybe the noise is coming from somewhere else? Suspension, exhaust? Fuel tank sloshing (which has sounded like a low clunk to me at times)?
#70 of 1820 Noise from the rear by hopeitsfriday Jan 10, 2003 (8:18 pm)
I have a 03 MDX and it makes a very low thunking noise once a while. Not really enough for me to ask my dealer to look into it. I dont think its the brakes, because it happens even when I am not using the brakes. Sounds like either the 4 wheel drive system engaging and disengaging or the rear suspensions. Did anyone out there do a suspension tight down at their 7500 mile maintenance? Did it quiet down the noise or no change?
