2001 Ody 93k Miles. Check Engine Light and TCS light came on during a trip to Ohio from Virginia on the PA Turnpike two days ago. The TCS light went off upon arrival, but the Check Engine Light stayed on. On return trip checked the codes. P0420 points to the catalyst (which I had worked on last November covered by Honda). P0740, I don't have a clue other than the analyzer said TCC circuit malfunction. Since the catalyst should be still under the dealer's 12 month 12,000 mile warranty I not worried that much about it. However, what's TCC circuit malfunction and is it going to hurt my pocketbook?

Thanks!

P740 is problem with the transmission lock up control. Think the 2001 is covered with extended warrenty to 100k. Check with your dealer. Hope you didn't reset the codes as dealer may not do anything until they return.....

Yes I agree...Take it to the dealer before you are out of the 100k extended transmission warranty. Even if it ends up not needing a new transmission you'll have documentation of transmission problems before 100k, so if it fails after the extended warranty you will have a better chance getting a "good will" replacement.

Thanks for the info.

Took it to the dealer today and their diagnosis is a new tranny. It will be installed in a few days all under warranty.

The dealer thinks the P0420 coming on might be related to the transmission malfunciton, so they'll reset the check engine codes after installation of the new transmission and see if the code returns.

B.T.W. How long should the replacement transmission last? In the past nine months, this car has had several repairs, all thankfully covered under extended warranty (EGR, Catalyst and now transmission). I'm concerned that this once reliable van is now showing signs of age far exceeding its 5 years. I've owned 5 Hondas, with my 86 Accord lasting 18 years and almost 200K.

Good news (kind of) on your transmission. How long should it last?... Much longer than 100k that's why Honda put an extended warranty on them. The average here seems to be 60-70k for those that have had transmission problems. Don't be scared though, some members here have gotten 150k+ out of a transmission and a few have almost 200k on them. Seems to be the luck of the draw for each transmission.

I kind of feel your dealer is taking the lazy/cheap way out of your CAT issue. By resetting your code they are just basically betting the next time it comes on you will be out of warranty. There are other issues that could cause the code you got besides just the cat. O2 sensors might need to be replaced for example. The Ody has two O2 sensors (one before and one in the cat). The computer reads these two and if the readings or not within a range between the two that codes gets tripped. So you could have an O2 sensor that's not working correctly not your cat.

With all that being said... I get that code once or twice a year. I have also replaced my cat (used an aftermarket one) and still receive that code. Since I'm no longer under any warranties I do too just reset it and go on. I am still getting great gas mileage (~25 mpg Hwy) so I have no motivation to fix what might be the real problem, my O2 sensors.

So far you have had everything covered. However you are coming up on a 105k service. Timing belt, spark plugs etc. Very pricey. $800-1000 Start saving.

I had a reman tranny installed @ 138k...1st tranny for this van..what ATF should I put in it?...

Honda only!

How strict was Honda on service records for warranty tranny repair? My records aren't the best, have similar codes and was told by my mechanic to got to transmission shop. Transmission shop said mechanical failure, new tranny, $3k. I have 59k on my 2001 Odyssey and have had my Odyssey serviced regularly by my local mechanic, but just don't have good records.

Learn to file. Keep the notices Honda Corp. sends you. Read them. See a dealer. They don't bite. Really!

Shouldn't be a problem. You still have low mileage and the transmissions on the '99-01's are covered under warranty until 100k. As long as your fluid level isn't low and it still looks..."Ok" They probably won't even ask. This is a known issue, they seen it, and do it all the time at the dealerships.

Go straight to dealer and receive your free transmission!

The ticket said the dealer replaced the Torque Converter at no charge. Is this the same as replacing the tranny?

Unfortunately the porters at the dealer side-swiped a concrete pole when moving the car causing a dent and white paint scuff marks on the right rear panel. They're going to be doing some body work on the car, also at their expense.

The P0420 code was noted in the repair documentation so if it happens again it should be covered under the 12/12k waranty of the EGR repair in November. At least that's what the service guy told me.
