I think you are about to see the rating of the '04 Odyssey plunge. We had an accident that resulted in our '04 Odyssey with 70,000 miles being totaled. We were so happy with the van that we went out and bought another '04 just like it, except it had a few more miles on it. 10 days after purchase the D light starts flashing, turns out it is a transmission problem. I do some research on the internet and there are HUNDREDS of posts showing that TRANSMISSION FAILS at 80,000 - 100,000 miles. There was actually a recall on the tranny for some '04 models, but those that were not included in the class action lawsuit or out of luck. Honda has refused to stand behind there faulty transmission!
A great vehicle if you are happy only getting 80,000 - 100,000 miles out of it.
Honda knows it has a transmission problem, they should save their reputation and fix it.
