this is a 4 cylinder autotransmission, all gears are shifting at around 32000 rpm ocasionally jerky shift
gears shifting at high rpm around 32000 + rmp fluctuates minutely when idle on 2000 Honda Odyssey
need to diagnose your transmission, you need to bring the van to your local trans shop and check your automatic trans fluid level first.
Make sure they know you check hondas with them shut off! lots of guys still don't know that and end up over-filling them causing lots of problems!///.......Does the "D" light flash at all when driving? If so you need to get the trans scanned --TRANS. shop or dealer.
