Honda Odyssey Transmission Problems



  • Thanks for the reply. I took it to the dealer this morning. It seems like I have broken motor mounts which will be replaced under warranty. 23k miles, already? Also the power steering pump and reservoir will be replaced under warranty (I had heard this would happen too). The car will be 3 yo on 12/22/10, so I had to get it in to do all the warranty work, although I realize drivetrain is 5yr-60k miles.

    I had already taken it in for the TCM in July, hopefully this thing will hold up.
  • I forgot to ask readers if they still had problems with the transmission if the installed an AFTER-MARKET cooker; like I had done at 264,000 kms.
  • Okay that's good no torque converter problem.
    There are lots of reports of the rear engine mount failing early because of the VCM (variable cylinder management) turning on/off 3 of the 6 cylinders. The extra vibration when the engine goes to 3 cylinders (unbalanced engine) puts extra strain on the mount. The rear engine mount was underdesigned. When the rubber engine mount collapses you have the engine sitting on top of the metal part of the mount and hence lots of vibration.
    Unfortunately I think Honda is putting in a new mount but it is still the old desgin so possible failure again in 23k miles?
    But wait a seond you said you have the EX and not the EXL so you should not have the VCM?

    I replaced just the power steering reservoir ($7 cost of part from Honda) and the whinning went away. This looks to me like a serviceable part meaning you replace it every so often just like an air filter. The reservoir actually has a mesh screen in the bottom of it. When it clogs it prevents enough fluid to go to the pump causing the whinning. The reservoir design has changed as well as now the cap is looser to let air out of the system like it is supposed to.
    So should you get the same problem in the future either replace it yourself or ask Honda to replace this $7 part before they replace the steering pump (big dollars).

    Lastly, the 07's are having lots of torque converter issues as per Consumers Reports Magazine (a recent spike) recently so it appears like more failures are occuring as the mileage racks up. Failure seems to happen at an average of 60k miles. So be very leary of any unusual "judder" you may experience while still under warranty. If problems begin to surface consider your options.
  • Hi again,

    You are right, my car does not have the VCM - wonder why there is an issue with the mounts.

    I must correct myself, I think they will only replace the power steering reservoir, I still have not picked up the car so I am not sure but most likely they won't replace the pump.

    I will remember the issue about the torque converter issue. The warranty is 5yrs or 60k miles for drivetrain for 07s, isn't it?

    Calm down folks. I stumbled upon this by accident.

    Here's what you need to remember: as others have said, CR ratings are survey-based. They are only reporting what owners are. If anything, the fact that the transmission rating went down should verify the overall accuracy of the ratings--it means it is picking up a known problem in the vehicle.

    The ratings are comparative. So, a "better than average/worse than average" rating for a 2007 is compared to others 2007s, 2003 to 2003, and so on. You guys are looking at this in a vacuum. The truth is, virtually every vehicle has issues as it ages, and Honda's apparently fare better than most as time goes on. If you look at, say, a Chrysler Town and Country for 2007, you're going to see several black dots and several more half black dots across a broad spectrum of components.

    There are hundreds of thousands of these vehicles on the road and relatively few problems with them. One of the known issues that does crop up is the torque converter issue and transmission issues. It doesn't mean that every vehicle has this problem, in fact most don't. But of vehicles that do have any type of problem, it generally is that.

    I did have the judder issue in my 2007, but the transmission was reprogrammed and it has been fine since and I just traded it. The "judder" issue was covered under the powertrain warranty 5/60k, but on my 2011 I'm likely going to add the 8/120k extended warranty just to be safe since its a first year model.

    Yes true. As I said the survery results are the survey results. That is not my issue. CR's take on "predicted reliability" is my issue.
    As I have said in previous posts we are not talking about a couple of cars having a few problems. Due to Honda's sharing of parts cross many platforms we are talking about many models with the same problem, and not just for a couple of years, but for more then a DECADE. To boot Honda's replacement tranny's have the same problem. So how does CR in their wishful thinking rate the 2010 as an above average buy.
    Yes every car have their problems but when I read CR I scrutinize Engine Major and Transmission Major as these are major costs and when they breakdown the car goes nowhere (boat anchor). Much more weight has to be given to what will not make the car move.
    I would rather buy a vehicle with black dots in engine minor, transmission minor, engine cooling, fuel system, electrical, climate, brakes, exhaust, or others.
    The little things you can fix on the cheap side. Engine and transmission replacement is often more than the price of the car as it ages.
    So......what is telling CR that Honda/Acura have their transmission problems resolved. They haven't done it yet in a DECADE!!! Why are they telling their subscribers go ahead and buy....predicted reliability better than average for the 2010?
  • Yes 5 years and 60K.
  • So I spent about $125 for the trans fluid change and got the power steering issue (they replaced both the reservoir AND the pump!) and the mounts for free under warranty. Both front and RS mounts were broken. Not sure why so early....
  • On a positive note for a change it sounds like 3/4 of the Odyssey's problems have surfaced early in your vehicle which can be looked at as a good thing because you are still under warranty.

    Mechanics on this forum recommend changing the tranny fluid with Honda's new synthetic tranny fluid DW-1 (Honda likely put this in for you) once a year.
    But I will change it myself so I can check the fluid for signs of damage or have an independent mechanic check it out. If Honda replaces the fluid they won't tell you if things look bad for your tranny.,
    Some recommend an aftermarket transmission cooler installation as well.
    It's hard to comment if this will work as there is not much blog history on these....sounds like people are just putting them in now so only the future will tell if they work.
    Sounds like it wouldn't hurt though and it's a bit of insurance.

    I would replace the reservoir (with the built in screen to catch contaminants once a year or every two years (it's only $7 from Honda and may save your pump from replacement in the future.

    Your mounts were replaced. It might be worthwhile to find out if they put in the same or something more robust. If Honda tells you the same mount.....well whats to protect you in another 23K?

    By following the above maintenance regimine maybe we can stay out of the shop for a long time.

    Good Luck and take care!

    Predicted reliability is based on survey results. Compared to other vehicles, year by year, the Honda Odyssey has been more reliable, therefore the predicted reliability on a new van is better than average. That isn't supposed to mean that there are NO issues, just that there are FEWER issues.

    There are tons of older Honda's running around with these parts that have never had a problem.

    I'm not sure what your beef is. The survey results are perfectly transparent, anybody can see for themselves what they are and then make their judgement. Apparently you have decided that you'd rather pick a different (actually several different) poisions. I don't happen to agree with that decision, but it isn't my money.

    As a way of protecting myself, personally, I'm going to use my money to purchase the extended warranty on my new 2011 Odyssey. Not because I expect the vehicle be unreliable--my 2007 was very reliable, the only issue on it was the aformentioned torque reprogram. But because any vehicle, once it reaches a certain age and mileage, is more likely to see some kind or problem, and with all the technology in these vehicles, those problems are pretty expensive to fix. For roughly $1200 I can be protected for the next year 8 years, 120,000 miles...seems like a smart decision to me. If I never have to use it, then so be it.
  • I'd suggest you take a look at the Equinox forum before making any decisions. I also like the Equinox but I would not touch one until all the problems clear.

    I would be buying, not leasing, in which case I could be stuck with a lemon.
  • I read the Equinox problems thread and it was a long one but it sounds like GM has got the problem fixed.
    The main poster was actually visited by a GM engineer in person who reprogrammed her PCM's "auto-grade braking" software.
    Sounds like the posters agreed that this was the problem.
    Interesting that Consumers Reports magazine also identified the Equinox's and Terrain's "reluctance to downshift".
    But I believe this new software came out in September so the problems should be licked.
    I test drove one last week and did not even remotely experience any problems.
    Speaking of CR they have rated the Equinox very well over the past 5-6 years. No rows of black dots for the big items (tranny and engine).
    Those are the ones I care about when I buy not the pittly stuff.
    Although I have bitched about CR before because of how they totally missed the boat on the Odysseys!!!
  • Now I would like to start a new thread discussion. It's still part of transmission problems though.


    When you've (Honda) had a string of bad luck of transmissions falling apart would it not be a good idea to do whatever you can to keep it going as long as you can?

    So Honda knows my 2007 Odyssey has torque converter reliability issues. They are burning up. They tell me cause my PCM software had to be updated. I don't know.
    But otherwise would it not hurt to change, not flush my transmission fluid more regularily and the big one, change the filter.
    Over the past 4 years and 60,000 miles they have only recommended and flushed (1/3 of the transmission fluid) tranny and haven't changed the filter.
    What is up with that?
    Honda says the filter is not user serviceable.
    I'm getting the opposite info online.
    It's not as easy as changing and oil filter but not that much more difficult on a 2007.
    I don't know maybe they just want to replace the transmission instead of the filter?
  • I have a 2000 and 2001 Honda Odysseys. Each one has had 4 transmissions. The original milage was 89,000 miles and 82,000 miles. None of the Honda rebuilts lasted 20,000 miles. Each time they replaced saying its unusal for this to happen. Each time I was out the time of repair. Each time I was told that the rebuilts should last the life of the vehicle.

    Now after a register letter to home office, they assigned it to a woman in the complaint department. After review they said that it was not worth their expense to replace these again since the milage on the one was 160,000 miles.
    I countered that the car is in good working order with no damage to the body, and that I have purchased 12 hondas in the past 10 years, and they can check that. Her final answer was that their finding is final. i told her that they were putting an expieration date on the Honda's by putting a milage limit on the Oddysey's. She never flinched and didn't even care if I never bought another Honda again.

    This means your Honda has a limited value now set buy the milage. Your auto is unrepairable after 160,000 miles and Honda will not honor their poor workmanship regardless. It also says they do not give someone like me special treatment or priority for my faithfulness in their product. In fact they do not care!

    I requested back in August a letter stating her findings and statement. To date I have not received a thing. Guess the sweeping it under the carpet is their best defense. To bad there isn't a class action suit, as I have two cars that can speak volumes.
  • I am also on my 4th transmission the 2nd one was paid for and 3rd was still under warranty but now i was told that i was lucky because i actually had gone a little over on millage because when the 3rd was replaced it didn't mean it came with a new warranty the old warranty was still in place must of forgot to let me know that when it was replaced because no where on the paper work does this indicate that. And with this one the 4th their will be no warranty crazy huh! Oh and i guess that they have fixed the problem now and i wont have to worry about it anyway so lots and lots of people have had similar experiences as i have with transmissions. I really feel like we should all be refunded the 4000 that was paid on the 2nd that they now know was faulty but fixed yea i hope so.

    Hello - just bought a 2010 touring and have about 7k miles on it. about 2k I took it in for vibration during decel. They put in the new software and swapped tires. still same problem. took a snap shot and sent it to Engineering. Customer service says its in tolerance. Curious if you still have vibration problem.
  • stickguystickguy Posts: 25,302
    the tolerance for a shaking/vibration under decel should be none. If it was me, I would keep taking it back for the same complaint until they either fixed it, or it qualified for lemon law!

    I assume you don't mean a shaking from the brakes, which could be warped rotors? Though that should be the first thing checked.

    odds are it could be the TC. But, at least you are under warranty for years to come, so if it is that, likely the problem will get worse until they can't deny it exists.

    2015 Hyundai Sonata 2.4i Limited Tech (mine), 2013 Acura RDX AWD (wife's) and 2015 Jetta Sport (daughter's)

  • Stick guy makes some good suggestions of things to check.
    Your vibration sounds different from everyone else's on this Forum.
    Torque Converter problems usually have a sympton of "shudder" which is very noticeable and feels like you are driving over rumble strips when you are driving at a constant speed between 35-45 miles per hour on a slight incline. There is no mistaking this as a TC problem.
    I have read several technical service bulletins from Honda/Acura about this specific problem and the fix is a software update or if that doesn't work then a TC replacement or entire transmission replacement.
    You describe your vibration as on deceleration.
    Does your car vibrate if you coast to a stop (don't touch the brakes)?
    Another common issue with the EX-L and Touring models is premature failure of the rear engine mount. Due to the constant vibration of the VCM when is turns on/off 3 of 6 cylinders this puts extra wear and tear on the rear engine mount. A Honda mechanic should be able to check for you to see if the mount has failed and the engine is directly sitting on the car frame. This is a very common cause of vibration for the Odyssey's.
    However, it is usually felt on acceleration.
    Last thing, if you have the run flat tires, these tires have been a nightmare for those who own them. Did Honda put on the same run flat tire?
  • Riduculous, so I guess Honda is saying at 160,000 miles thats when most cars transmissions fail so you are on your own!
    Okay then Honda....take the same spiral down in sales as Toyota has in sales when you are not honest and try to hide your problems.
    These guys better realize that the majority of consumers don't complain but walk with their feet instead. A silent killer of automoblie sales.

    My 2002 Honda Odyssey transmission was broke in 2006 and honda replaced it with a re-manufactured one for $2600. it broke again in oct 2009. The dealer said eventhough it is within 3 yr warranty period my miles has exceeded by 600 miles. So the dealer indicated that I am basically screwed. I have decided, let's go American. I have advised all my friends and family members to avoid Honda.
  • I bought my car new, and had every service done by the dealer. Now, with only 95,000 miles on it, they say I need a new transmission for $6,900. The dealer submitted a case to Honda America with all my service records, and within minutes they turned down the request for help and refused to do anything. Nothing at all. I feel completely burned by this company. Is there anything I can do to get some justice? Another class action lawsuit?
  • I got the same run around and got similarly blown off. Then I went to the Honda Odyssey Facebook page and detailing my story:

    I then called up Honda and told them what I was doing and it was my attention to let everyone know that Honda doesn't stand behind their products. I directed them to the page. I said it was magical that with Facebook I was reaching potentially millions of potential Honda owners and yet for $3000 Honda was willing to sacrifice much more. Magically, they fixed it for free the next day.

    Similar to my story. My 2001 tranny died at 91K about 1 year ago (although in hindsight it was showing signs of problems before that...wish I had that 20/20 back then). The $6.9K you were quoted seems high. I was quoted a little less than $4K at the Honda dealer (in New England) for a rebuilt tranny, installed. I would also get a quote or two from a local shop to rebuild your tranny...should be nowhere near $6900 (my local shop quote was about $2.2K if I recall). I contacted American Honda directly (after the dealer did), and they ended up paying for 50% of the parts. I paid for the labor. So, doesn't hurt to contact American Honda directly. You're still within the mileage limits of the extended warranty, although depending on your in-service date, you're around 2 years beyond the time (I was about 8 months beyond the time limit when mine failed). Good luck. Ended up fixing ours because I didn't think I could replace the vehicle for my net cost to repair it.

    That price is insane. Jasper will sell your local shop a transaxle for much less. You will still pay about $3,000 to get it done, but Jasper offers a 100,000 mile warranty with their units.

    If you live near Ohio, let me know. I'm a tech at a dealer and I rebuilt the transaxle in our 1999 Odyssey. The parts cost me $600 and I provided the labor.
  • unfortunately it appears honda is going to deal with this one van at a time, and only by force, because it will still cost them less than simply saying, bring every van in for a 10 year period. There are several major problems they are not dealing with and simply can't afford to do it right by their products any more. Meaning that Honda is only as good as any other brand now, so adjust your expectations and shop around for your next car with open eyes. I am also stuck with a 2005 van with problems. Welcome to the new american life experience,...only as good as the rest of the world has had it for decades....and happy new year while we are at it.

    tHOnda has finally figured out what many re-builders have been saying for years. "Don't use the Z1 fluid."

    HOnda has now discontinued it and replaced it with DW1..a synthetic. Great, 10 years of burn up clutch packs and torque converters and finally they get it.
  • Interesting you should say that because when I took my Odyssey into Honda for transmission service recently they used DW-1 and not the old Z-1. The curious part is that when they do a tranny fluid "flush" that only gets out about 1/5th of the fluid. To completely "change" the fluid you have to do a procedure detailed at
    Essentially you drain, fill, and drive 5 times to get rid of all the old Z-1 poison out.
    The DW-1 is expensive, it cost me $240 to do the above procedure properly, but it may save your tranny. Also recommends that on Honda's you "flush" once a year, about 15,000 miles every year once you have the new DW-1 in the van.
    Hope this works!

    At 56K (Nov 2006) had transmission replaced under warranty. Now, at 93K (Dec 2010) transmission failed again, and Honda America refuses to help based on mileage and age of car. We hav only ever owned Hondas, which meant nothing to them. The new transmission was quoted at $4985 + $500 for new engine mount. They have us over a barrel.

    Even for Honda, 2 trannys in 100,000 miles is depressing...get on the phone and do some shopping for another rebuilder that has a good warranty. I'm sure you can beat that $5,000 quote easily.

    Then when you get your Ody back, don't ignore the tranny, it's very easy to do, but don't!

    Change the fluid every year, install a Magnefine filter on the return line to catch the wear and tear from getting back into the case, don't use the HOnda Z1 fluid..ever.
    Use a good quality synthetic like Amalie it's only $5.08 a quart shipped to your door free shipping in a case of 12. I know a very reputable re-buider who sends his trannies out with a 5 year 50,000 mile warranty and that's the stuff he has used for years without a problem.

    Actually, when you drain and fill a B7TA (the three shaft, four speed used from 1999 - 2001) you get about half the fluid each time. I know because I tore mine completely down. A service used 3.25 quarts, and the completely rebuilt unit took just less than 7 quarts. You can simply service the transaxle in your garage once a month for 3 or 4 months and get the same result.
