Anyone know more on the 10 speed in terms of specs? weight, torque? I've updated this info above. 👆

please verify.

 

Thx for summarizing all this fuego, will be super handy over time. Pinning would be great!

 

bump. had fixed few things + added in few more info.

 

This could help those that are having shifting issues on ZF 9HP. You can reset the transmission. Full disclosure, I did not try this because my van has learned how my wife and I drive. So far things are working great. But in case you need to do a relearn try the following. This has served the Acura folks very well. I'd give it a try if you are having shifting issues. I'd do this if the van was purchased second hand.

Here are the instructions for doing a transmission reset.

1) Push the START/STOP button: press it twice without pressing the brake pedal. DO NOT START THE ENGINE. Turn off the lights and radio.

2) Your dash lights should be on at this point. Within 5 seconds of turning on the ignition, press the gas pedal down all the way, and keep it pressed for 15 to 30 seconds.

3) After the transmission has reset, the CEL will go off.

4) Turn the car off and restart it.

There will be no confirmation or beep but at this point, the transmission has been reset. If you are not sure, repeat the procedure one more time.


Now drive 500+ miles for the full learning to take place.


This may work on the 10 speed? But I don't think the 10 speed is a learning AT. Please verify. + would love more folks to vote.

 

Is this gonna work on my 2019 Honda Odyssey EX. Thank you

 

Thanks for putting it together. Hope it gets credible information included and updated periodically.

Here are few corrections

10AT Facts
- The Fill bolt is in the front and faces the radiator and uses a typical 17mm, 6-point head. It is accessible from the engine bay, preferably from the bottom. The drain is the typical 3/8" style. Here is my DIY if needed >> DIY - 10spd ATF change

- the max torque figure is not fully known to the public (though an article, Just-Auto, listed such a number back in 2015). Depending on the configuration, it varies, though the transmission is the same. In the '19 RDX the rated torque is 280ft-lbs. The upcoming, yet unreleased, TLX Type-S is promoted at 354ft-lbs.

- Weight: about 220lbs dry (with no fluids) - source Gears Magazine: link below.


Resources
- Wards Auto is considered as one of the reputable outlets in automotive world. Their 10spd article is here >> Honda Details Front-Engine, Front-Wheel-Drive 10AT on Odyssey

- Complete tear down and review of components >> Gears Magazine | Planetary Gearsets in a Honda?

- Arturo Valdes' commentary of the 10AT >>

Recommendations
- Your intro about the Honda ATs is not factual. Though there were issues in the early to late 90s, the Honda transmissions have proven to be one of the stout units in the 5/6sp configurations. Unless you are able to provide a credible source graphing the AT stats that you provided, I would leave it out as it is just an opinion.

- Transmission limits are dictated by the clutch plates, fluid used and the torque converter. These fail, before the gears and shafts give way.

- If this is going to be a one stop shop for the 9spd and 10AT, then sources are very crucial so the discussions do not spiral downward. I also recommend you seek a moderator to keep the thread on point.

 

smufguy, thanks for the feedback I’ll go and fix these once I’m at a computer. I’m on a mobile phone and usually get some time to do this stuff when all the kids are napping/late at night.

I wish I had access to this information when buying my van. There is so much noise otherwise. On top of that folks only post if there are issues in these places.

 

You got it, it is the least I could do. I joined Odyclub about 7 months prior to buying my G5 and it had valuable information that was instrumental in my purchase. I am almost at 55K mi on my G5 in the last 2.5 years (almost) and it has been problem free. Even the recalls and TSBs had no symptoms; I really enjoy the van, but I still love my G1 Ridgeline

This community, like many others, have been inadequately moderated and thus you hear a lot of 'noise'. It is unfortunate, but expected. Regardless, it is a great resource that needs to be treaded carefully and information retrieved with certain level of skepticism.
As with every other online community, people either talk about modifications or complain about issues. You wont see a slew of threads and discussions about how their vehicles are problem free.

 

Just made some tweaks according to smufguy's input. Took too long, I didn't get a chance to get back on here in a long while. Thanks to everyone that have voted. (Please remember I am not an expert, I visit this place once in awhile to see what's happening in the world of minivans of all things, as interesting as it sounds.)

 

2018 with the 9 speed. At 50K miles the van started making an odd noise, wasn't sure what it was but sounded more like a wind noise very faint. At 62K the van started to have a hard shift when decel, at 64K the noise increased. At 66K we are told we need a new transmission at the tune of $6K as it is just outside of warranty.

Ahhh.. that’s terrible. Please record this on the survey.

Also, would love hear back updates on the replacement unit.

This is the only way we can record these events for now. On the long run if this survey is still being updated it may help us out. I know there is a class action lawsuit on the ody 9 speed. Not on failures but the shift quality.

shoot we see significant numbers we might be able to class action that too..

All best.

 

Did you replace the transmission fluid when the code popped up?

 

I'm always a little skeptical when a newly created forum memeber immediately starts making claims of a premature (and expensive) failure.

There was someone else on this forum who would occasionally claim that his transmission failed at 75k miles. I have repeatedly asked for details by responding to his posts and sending a PM. He hasn't responded to either.

It is entirely possible that the previous poster's transmission failed, or he could be a forum bot who shows up for a few posts and disappears.

 

I'm not a bot, but I do have a 2018 sitting in the shop waiting for a new transmission after it failed at 46,000 miles. Transmission failed on 3/14 while we a were on a spring break road trip. It's 3/23 and it still hasn't been fixed, and we have been stranded for days out of town waiting for it to be completed. Honda refused to overnight the new transmission.

 

minor updates made above.

 

We bought our 18 EXL with 24k about a month ago and around 25mph it’ll suddenly lose power and slam into gear. You can hear an audible click when this shifting happens. Also, it wants to lurch forward if you barely step on the pedal. I tried resetting the transmission and drove it for 500 miles and it’s still doing it. I have an appt for Wednesday. I’m running all VLEDs but I was having the issue prior to the LED swap. Thankfully we paid the extra 1400 to get Honda Care for 8 years and 100k miles. I’ll post updates after our Wednesday visit.

 

This is awful. I noticed this 9 speed to be noisy/jerky when particularly cold. After driving a bit it smooths out. Unfortunately all this is coming from the design of the AT. Did you ever get the Software update: http://www.urvi.net/forumfiles/SB/A19-124.PDF
Ask for this at your visit if you didn’t get this yet.

 

Finally had the dealer perform TSB 19-124 on my '18 EX-L. Drove it about 20 miles and don't notice much of a difference. 0-10 mph shifting seems to be better, 30-40 mph, not so much. The dealer did reset the transmission and I'll have to drive it 500 miles for it to relearn, which will be awhile as we're not driving much these days.

As others have said, it's not a deal breaker for '18 &'19 LX-EX-Ls. The transmission is dependable and hopefully will last as long as the van itself. I got my Odyssey at a steal for $16.6k with 99k miles (KBB had it around $22k when I bought it 6 months ago). Don't pass up on good deals simply because of the 9-speed transmission.

 

Thanks for sharing the info, curious if you notice any changes after the 500 miles.

 

The van drives so much better after the TSB... it doesn’t slam into gear around 24-27 mph like it used to and I drove it how I knew I could duplicate the issue and had no problems. I’ll post updates after 500-1k miles. Time will tell.

 

That's great to hear!

 

Aclement1618,
Glad to hear it was working and the MOD (programing is what was needed) so many other people has had the opposite effect of still being bad. I am not saying all of those whom has the 9-speed has bad luck with it.

BTW, whom ever thought we needed so many speeds? What was wrong with a 3 speed? I just wondered if they did it to keep the RPM and transmission together for economy reasons.
We'll keep praying you have good luck with your ODY!

 

Pretty normal at the moment. My coworker had the engine blow up on her new Ford Escape due to a known defect. Took 3 weeks to get the engine and one week to R&R. Ford would only approve a rental car for 5 days.

 

@fuego great thread! Not a G5 owner but always learning about the new Gens. @JoannaJes , so u guys ended up taking the car to the nearest Honda dealership to get this done (out of the blue) while on vacation, due to it failing all of the sudden?...

 

Yes. It failed at a gas station on a Sunday afternoon, 7 hours drive from home. Towing service took it to the closest Honda dealership in town and left the keys in the dropbox.

 

Update for you all—

we said an early goodbye to the Odyssey and are now the owners of a 2021 Toyota Sienna. 😆 We haven't heard from Honda corporate yet or received any sort of reparation (I will add that the dealership has verbally promised that we would).

 

2021 Toyota Sienna.

Very nice. Best of luck!
My goal is to keep mine as long as possible. Bought new all paid for. It’s a big loss if I sell/trade now. So far no issues and hoping it will stay that way.

 

Congratulations on the sienna..

While we love our Odyssey, there is no beating Toyota quality and reliability. We've had Pirus's, Camry hybrids and the last car we had before the Odyssey was a Highlander hybrid, so going to the Sienna hybrid would be a no brainer. If we could afford new, we would definitely get the Sienna over the Odyssey.

Hopefully, this makes sense... I haven't updated my response to the poll because I wanted to get more mileage in. I wonder if Honda will come out with another software update to adjust the pedal/acceleration feedback. When I driving the van I find that I'm sitting in a somewhat tense position (to anticipate the shifting) until I turn on cruise control on the highway. There's almost no consistency with the acceleration.

I feel the exact same way. The gas pedal --> feedback response is out of whack. It's as though you must make an appointment when you want to accelerate from a stop light, in case you hurt the transmission's feelings!! I spoke with my service advisor about this oddity at my previous recall appointment. He said the 9-speed must be "driven." He meant that you have to lean on the gas or else the feedback is not smooth. So much for the goal of excellent gas mileage.

The best I can describe the 9-speed is with simple math. Every car I've owned had a mostly linear acceleration response. The more you press the gas pedal the faster you go. The 9-speed is parabolic. You press the pedal and the car has to be woken up first, then all of a sudden it snaps at you - kind of like waking up a teenager for school !

 

Bump

We need to report here instead of starting another transmission failure thread. Wish we could get it pinned. I’ve manually added in the number of failures on the 1st post for those the didn’t place their vote in the survey

survey input + reports on other threads we have these numbers below. Happy to report not all 5th gen odyssey’s out there are blowing up folks.

[9 speed failures: 4]
[10 Speed failures: 8]

 

MDX 10 speed AT cooler

I know the 10 speed ody won’t have any use for this but here it is. Waiting for them to upload some diagrams soon.

 

Dropped my van off at Honda of Mission Valley for 30k. The trans service is $280.74. I’m having them look at a few other items, will update if anything comes out of the trans issue…

 

Brand new 2022 Odyssey EX-L with 100 miles on the odometer and the transmission is toast. Dealer is looking for a new one. Symptoms are that when it gets up to 30-40mph and you give it gas it just revs up quickly but no acceleration whatsoever. Also it sometimes is extremely slow to accelerate from a stop.

I should have bought a Toyota. Expensive lesson learned amd hopefully future readers will benefit.

Sorry to hear this. Thanks for reporting. Glad it is covered by warranty. Hate to wrench on a new vehicle 😕
