Repair 1999 Honda Odyssey or move on?

My BIL and I have 2000 & 2001 Odysseys, respectively. Some will throw an OBD code that indicates that the catalytic converter is out of range. I would have the oxygen sensors that trigger that code checked to make sure they are not the cause of the code. It is a case where the messenger might be wrong. My transmission was replaced under warranty, too. Make sure you drain and fill the ATF every year or so. Also, if the EGR passage gets clogged (it will trigger the check engine light), it will cause the tranny to act weird. Odysseys have some quirks, but if taken care of, they are very good vehicles.
