What does it mean 2003 Honda Pilot blinking d light?

Answer 1

You could get the codes read, but it's likely the tranny isn't locking

properly. Change the tranny fluid with Honda Z1. Drive it a while and do

it again. Some will tell you to do it a third time. Whatever you do,

don't put anything in it that isn't Honda brand. While you're there,

order the Owner's Manual from the dealer. It's well worth it. You can

change the ATF yourself, or take the fluid to Monkey lube and let them

do it while they change your oil.
