no cel light or flashing s at all, I have searched keywords all over stuff like "accord transmisssion not shifting" etc and all i can honestly find is a bunch of uninformed idiots asking if a automatic can be shifted manually or is it deadly or not to flush the fluid. believe it or not i have found people asking why the car goes backwards when put in reverse?????????????? I am a 20 year mechanic by trade,and was hoping to find someone else who has some experience with hondas instead of a imaginary racing school made up of hot rod import posters and funny looking yellow plug wires and stainless intakes on otherwise granny cars. but well I am from a different generation. seriously though, if anyone has similar trouble I would appreciate any ideas, and to madhat, thanks for your reply, can you advise further, thanks Bob
