Honda's only had transmission problems in their 1998-2001 Honda Accords where there was a recall and Honda fixed everyones transmissions for free.Ever since that happened, everyone thinks that all Honda's around that age have transmission problems, but that is not true.The Honda Odyssee has won Car&Driver Magazines 10 best list almost every year for the past 10 years. It is a great car. It will last at least 300,000 miles. You probably will not need to replace transmission until after 150,000 miles.We have had minivans and we know people who have the Honda Odyssee. We now have a Honda Accord and Toyota Rav4.
