Hello! I'm new to this forum and I'm thinking of replacing my 98 Toyota Sienna with an older Honda Odyssey because it's insanely difficult and time consuming to change the 3 spark plugs that are on the backside of the Sienna engine.

I have two questions, please...

1) I read that a few of the early years of the Honda Odysseys had a lot of transmission problems. Can anyone tell me what those years are so I can avoid them, please?

2) For the good years of Odysseys (the years with NO tranny issues), is it easy for non-mechanics to replace ALL of the spark plugs?

Thank you! :-)

 

Anyone?
