I have been researching this issue concerning the transmissions. I have some informaiton on the recalls posted at WWW.NHTSA.DOT.GOV. Recalls Summary

Make / Models : Model/Build Years:
ACURA / 3.2CL 2001-2003

ACURA / 3.2TL 2000-2004

ACURA / MDX 2001-2002

HONDA / ACCORD 2003-2004

HONDA / ODYSSEY 2002-2004

HONDA / PILOT 2003-2004

Recall Number: 04V176000
Summary:
ON SOME MINI VANS, SPORT UTILITY AND PASSENGER VEHICLES, CERTAIN OPERATING CONDITIONS CAN RESULT IN HEAT BUILD-UP BETWEEN THE COUNTERSHAFT AND SECONDARY SHAFT SECOND GEARS IN THE AUTOMATIC TRANSMISSION, EVENTUALLY LEADING TO GEAR TOOTH CHIPPING OR GEAR BREAKAGE.
Consequence:
GEAR FAILURE COULD RESULT IN TRANSMISSION LOCKUP, WHICH COULD RESULT IN A CRASH.
Remedy:
ON VEHICLES WITH 15,000 MILES OR LESS, THE DEALER WILL UPDATE THE TRANSMISSION WITH A SIMPLE REVISION TO THE OIL COOLER RETURN LINE TO INCREASE LUBRICATION TO THE SECOND GEAR. ON VEHICLES WITH MORE THAN 15,000 MILES, THE DEALER WILL INSPECT THE TRANSMISSION TO IDENTIFY GEARS THAT HAVE ALREADY EXPERIENCED DISCOLORATION DUE TO OVERHEATING. IF DISCOLORATION EXISTS, THE TRANSMISSION WILL BE REPLACED IF DISCOLORATION IS NOT PRESENT, THE DEALER WILL PERFORM THE REVISION TO THE OIL COOLER RETURN LINE. THE RECALL BEGAN ON APRIL 21, 2004, FOR PILOT, ODYSSEY, AND MDX OWNERS. OWNERS OF THE ACCORD VEHICLES WILL START RECEIVING LETTERS ON JUNE 28, 2004, AND ON JUNE 29, 2004, FOR OWNERS OF THE TL AND CL VEHICLES. OWNERS SHOULD CONTACT HONDA AT 1-800-999-1009 OR ACURA AT 1-800-382-2238.
Notes:
HONDA RECALL NOS. P30 (ODYSSEY AND PILOT), P31 (MDX), P38 (ACCORD) AND P39 (ACURA). CUSTOMERS CAN ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION’S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).

Not sure if your having this problem but if you are, The number is listed.

2001/2002 Tranny issues are a well documented issue here. Having the recall mods performed does not really improve your chances of tranny failure for these model years. If you search you will find numerous threads discussing the issues and recall. The MDX tranny was redesigned in 2003 reducing the number of tranny problems to well within industry norms for 2003 and well above industry norms for 2004 and up.

I take it that you work for Honda Motors Corporation. Your the same person that keep asking me questions like are you the second or third owner, Do you tow with this vehicle. You must work for honda. I know what this vehicle is doing and what the transmisson fluid looks like when I change it. I don't drive the X's far and I take care of my vehicle.
chines867
The only thing that I am pointing out by posting the theard is that 2001-2004 the honda/acura vehicles have been having problems with the transmissions. But 2003-2004 MDX problems have been solved right. Unless than one year they fixed the problem.

I never asked you those questions so you must have me confused with someone else. I do not work for Honda, I can, however, read consumer reports and their complaint rates. It looks like you have a 2003 from previous posts. If that is the case, then the 2003 has a transmission problem rate of less than 2% and you are in that 2%. And that figure comes from surveys from real owners not from Honda/Acura. To put it in perspective, that rate is much better than say a Mercedes M Class or VW Touareg which have a much higher transmission problem rates. The 2005 Toyota Sequoia has a less than 2% tranny problem rating also - the same as the 2003 MDX.

The 2001/2002 model years have a much higher than normal failure rate. The transmission was significantly redesigned in 2003, resulting in the less than 2% problem rate. I am guessing that further minor changes resulted in the less than 1% problem rating for the 2004/up model years.

If you’re not the same person that has asked me questions in the past concerning my MDX then I due apologize for accusing you of doing so. I would also like to point out that I’m also a member of Consumer Reports. The information that is being provided there is biased of people that respond to the Consumer Reports survey that is done on an annual basis, not everyone responds and not everyone is a member of Consumer Reports. The following information is also provided on the top page of that report, it’s a report of the reliability rating and how Consumer Reports calculates the ratings. Details are provided in the Reliability History Section. It’s also why sites like Acuramdx.org are so important to all of us. December 2006
A guide to used-car reviews
The tests and considerations behind our used-car profiles



CR Good Bet

The CR Good Bet symbol is given to models that have consistently done well in our tests and have had consistently above-average reliability.

Major redesign
Here we note the model year or years that the vehicle received significant design changes. In between major redesigns, a model typically remains the same from year to year, sometimes with minor changes in styling, trim, features, or the powertrain.

Drive wheels
This tells you whether a vehicle uses front-wheel drive, rear-wheel drive, four-wheel drive (4WD), or all-wheel drive (AWD). 4WD is available as part-time, permanent, or selectable systems. In both permanent and selectable systems, 4WD can be engaged all the time. Part-time 4WD can't be used on dry pavement. AWD is similar to full-time 4WD, except it doesn't include low-range gearing, which is most important for serious off-road driving.

Related models
To cover marketing niches without having to invest in manufacturing, many car manufacturers sell essentially the same car under different nameplates. Or they may sell another manufacturer's car under their own name. We note any such relationships.

Overview
Consumer Reports' assessment based on testing and research through the years covered.

Safety equipment
We note the availability of air bags (front, side, and head-protection) and antilock brakes for each vehicle. We also note the presence of front safety belt pretensioners. Government regulations require all new cars and light trucks to have dual air bags and to comply with a side-impact standard.

Reliability history
These charts are based on more than 1.3 million responses to our 2006 Annual Subscriber Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the previous year (April 1, 2005, through March 31, 2006) that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below.

The scores in the charts are based on the percentage of respondents who reported problems in each of the 15 trouble spots. Because high-mileage cars tend to encounter more problems than low-mileage cars, problem rates are standardized to minimize differences due to mileage. The 2006 models were generally less than six months old at the time of the survey, with an average of about 3,000 miles.


HOW TO READ THE CHARTS

To check on the reliability history of a particular year's model, start with the Used Car Verdict. This score shows whether the model had more or fewer problems overall than the average model of that year, calculated from the total number of problems reported by subscribers in all trouble spots. Because problems with the engine, cooling system, transmission, and drive system can be serious and expensive to repair, our calculations give extra weight to problems in those areas.

To see how the model that's currently on sale is likely to hold up, look at the New Car Prediction at the bottom of each chart. For this rating, we averaged a model's Used Car Verdict for the latest three years, provided the vehicle did not change significantly in that time and hasn't been redesigned for 2007. We have found that several model years' data are a better predictor than the single most recent model year. One or two years' data may be used if the model was redesigned in 2006 or 2005, or if there were insufficient data for more years. Sometimes we include a prediction for a model that is new or has been redesigned, provided its reliability history or the manufacturer's track record has been consistently above average.

To see a model's individual strengths and weaknesses, look at the individual scores for each of the 15 Trouble Spots. The "Average Problem Rates" chart shows the average problem rates for all models in the survey in each trouble spot. Scores are based on the percentage of survey respondents who reported problems for that trouble spot, compared with the average model of that year.

Models that score a are not necessarily unreliable, but have a higher rate of problems than the average model. Similarly, models that score are not necessarily problem-free, but had relatively few problems compared with other models.

Because problem rates in some trouble spots are very low, we do not assign a or a unless the model's problem rate exceeds 3 percent. If a problem rate is below 2 or 1 percent it will be assigned a or a respectively. In the charts, a model year in red identifies the year of a major redesign.


What the trouble spots include

Engine major: Engine rebuild, cylinder head, head gasket, turbocharger, and supercharger.

So far Consumer Reports reliabilty results have reflected my own/friends/coworkers/relatives/etc experiences very well. In any survey or medium, those who have problems are more likely to respond than those having no problems. That would lead to problems being over represented in the reliability summaries. This forum is the same way - people with problems seek out an internet forum to discuss their problems. So a few people discussing a problem can result in a thread that looks like it is a huge problem. And this forum represents less than 2% of owners.

In regards to transmission failures reported on this site, you will find plenty of 2001/2002s and very few 2003s which is reflected in the CR results.
