It cures the problem
"Sonnax patented the valve, but if Honda is smart, there's more than one way to skin a cat. The TransGo kit does the same thing, but has no provision to avoid converter drainback after sitting overnight. Honda, and any carmaker for that matter, only concerns themselves with things that affect them during the warranty period. It takes a group effort (sometimes a class action suit) of dissatisfied owners for a carmaker to take notice. Clogged screens, clogged filter, and etc. are caused by too much debris in the transmission fluid. Honda did R&D and said the microfinish of the steel plates was too rough and wearing down the clutches. Their fix was mirror-smooth steel plates. Raybestos, agreed, but came up with a different fix: Harder and more durable clutch lining. Either/or... the bottom line is that clutch wear creates debris. It creates the majority of the debris that clogs up filters and screens. Having an inline filter is one of the best investments a Honda owner can do because it filters much finer than the factory filter. The factory filter isn't a filter at all. That's a misnomer. It's a pump suction intake screen. It's 60 microns which is big; the size of the human hair. A true filter, filters down to a size where you can't can't see what gets through.
Until the MaxiFlush, 15 microns was the best available with the Magnafine, which is 4 times finer than the factory. You can't filter any finer that 15 microns with a full flow filter without restricting flow. It's a combination of not only filtering the ATF much finer than the factory, but also generating less debris in the first place. Fixing what generates debris is part of what fixing the converter fluid flow is all about. The converter generates a lot of debris by the clutch dragging when it's supposed to be off. It also loses flow when hot and melts the aluminum washer in the converter, generating even more debris.
It's quite a complicated fix making a Honda trans long lasting. There's no one "silver bullet" that solves all problems; I wish there was.
Lastly, here's what I have to say about Hondas: What use is a long lasting vehicle if the transmission isn't?"

1. What should I do now to best increase my chances of longevity with this transmission? I've read several things, and maybe missed some...(after-market cooler, in-line filter, DW1 fluid, Sonnax pressure reg. valve) All of this, some, more??
2. Should I flush or drain the tranny? I get both answers when I research issue.
3. How often should I flush or drain?
I should add that this van was part of the recall in 2004 and I have paperwork that shows it had a jet kit of some kind installed in the transmission at 18,000 miles. ) This receipt was buried in a stack of oil-change receipts the seller gave me...I missed it when I was buying the vehicle)
We just had a Grand Caravan transmission die on us (on our 11th anniversary "date" no less!) and thought we were getting an upgrade in quality. Other than a fear of future problems with transmission, we love this van so far.
Any help or advice would be greatly appreciated! Thank you in advance.
1.) Install a quality after market cooler, and service the transmission using Honda's new synthetic fluid.
2.)Drain and refill, Flushing is a waste of money and fluid in my opinion.
3.)Service it now, again in a month, and then annually.
The oil jet service campaign refers to a fix to keep the second gear cooler. As long as it was done, you should be fine.
I had them do the work and they did it for a fair price. I paid $3000.
However the warranty was not as easy as they claimed it would be. I've had the shuddering issues between 40-50 mph and have had it back at AAMCO in Kalamazoo multiple times. They cannot find the problem but I can drive it and make it happen.
Needless to say, the warranty is over and I still have issues.
In looking back I should have rented a car hauler from U-Haul and towed my car back home and had a local mechanic do it. I would have paid a little more and installed a Jasper transmission. Their's comes with a 100,000 mile warranty.
I am not pleased at all with AAMCO. I felt they did not live up to their warranty. My advice...shop some place else.
The next day they called and fixed my Odyssey.
You have to make it painful for them and let them know you will make a stink.
The squeaky wheel gets the grease.
-Took the car to my mechanics specialized at Honda and Acura for a test drive. The tranny problem got confirmed and got a quote of $3200 with 1 year/12,000 mile warranty.
Called American Honda and was told to a dealer. Did that and got confirmed and a quote for $52K with 3 year/36,000 miles warranty. American Honda decided to help with $10000.
I treated it in and bought a RAV4 at a Toyota dealer. I would be very concerned to buy a big Honda car in the future. Honda seems not good at making long lasting transmissions for big cars.
I first started noticing the slippage at about 125,000 miles in Spring 2010. We had the 4th gear pressure switch fixed at 130,000 miles (over $200)...but it didn't fix the problem, so we had the transmission rebuilt at 139,155 from a local transmission center ($2633) NOT THE HONDA DEALER. That came with a 2 year or 24,000 mile warranty. In April 2011, while on the highway the transmission started to slip out of gear and lose power and the car overheated. I towed the car back to Massachusetts from New York (at a cost of $800 which I swallowed) so the transmission place could fix it again. They did.
We paid the car off on August 1st, but on August 9th at 139,155 miles, the transmission (AGAIN!) died. Again, it was on the highway at about 70mph, when the gears slipped. I sat on the side of the road for 2 hours with my wife and 5-year old daughter until AAA got through a traffic jam. (I called the police but they police never arrived!). Oh, by the way, we have put 29,000 miles on the car since the transmission rebuilt last year, so we are 6,000 miles beyond the warranty. My mechanic thinks it is electrical - either the Throttle Position Sensor (telling the transmission to downshift at 70mph) or something else electrical/computer related.
This car is dangerous. I want to unload it, but hoped some dealer might take it for a trade-in. Unless Obama brings back Cash for Clunkers, though, I have feeling that I am out of luck.
- There's a press release on the Honda website http://www.honda.com/newsandviews/article.aspx?id=2002092028798 where they admit the transmission problem. It also contains a statement from their Executive VP saying "Our priorities are making sure our customers are taken care of and reassured they can continue to depend on their Honda of Acura automobile for a long time to come.". Is any part of that statement true for you?
The Internet has several message boards, complaint sites, and a ton of information that has to do with Honda's transmission problem. Here are a few that I had saved to my favorites:

If you end up pursuing the small claims case, you're going to want to go after American Honda as your main target, not the dealer. It's okay to name both in the suit, but American Honda is the one that holds most of the responsibility. They're the ones that built the vehicles with the faulty transmissions, set the warranty, extended the warranty, and are the ones that reimburse the dealer for any warranty work the dealer performs.
Secretary of State website by State and do a Business Search for "American Honda". It gave the name and address for the Agent for Service of Process.
This should get it done.

To change the transmission filter on an Ody 05 there's limited enough room to get at the cover plate. Many have done it but the space is very tight. I removed the air cleaner to get access, but the filter sits under the VSA modulator/controller and it's difficult to lift the VSA high enough to get the bolts and cover off without bending brake lines, etc. The filter is so tiny that you have to believe that it was originally designed to be replaced every 30K miles or so but then someone at Honda decided to locate the VSA controller right over the filter access plate and it became a "non servicable part". Other considerations are to just put a Magnafine filter in the line for safety and maybe try again sometime in the future to replace the Honda filter.

Sure, you would love to see the tranny last as long as the engine, but with that kind of miles, I don't see that Honda really has an obligation to pay for it.
You mention GM cars. If you had bought a venture van instead, and it puked a trans at 160K, would you be going after GM, expecting them to do anything about it?

Here's the link to file your complaint. It is the only way to get the govt to force Honda to do anything.
Personally, I'm having a large sign printed to display on my PT Cruiser that Honda Odyssey's have reputation for Transmission Failure!
Posting it on Craig's List For Sale - Needs Transmission. Might get a little something by someone who can do the work.
Honda Odyssey transmissions are KNOWN to fail at even 40 or 50K miles REPEATEDLY.

and Honda REFUSES to fix their mess!
SHAME ON HONDA!

"you can't keep making the same mistake over and over and expect a different result"
As for your 05', I would get the Honda ATF Z1 fluid out of it ASAP and get it filled with the new DW1 sysnthetic fluid. Ad an in line Magnefine filter to it and put it on a strict fluid and filter change every 30,000 miles.
So how many if you out there have had your Honda Ody transmission replaced more than once?
