might be too full. Look at owners manual for checking fluid. Think checking with van off

Fuid level is checked with engine 'off' on Hondas'

The 2001 & 2002 Odyssey transmissions are poorly designed and overheat, causing the fluid to boil out. Honda had a recall on the 2001, but have covered up the 2002 problem. I solved my problem by getting a rebuilt from a 3rd party where they improved on the Honda design and added an external oil cooler. Don't replace it with OEM, as it is defective engineering.
