Well then it's a 40, which is lock up control system. The procedure is basically the same as it is for P0730 which is already posted in this thread. Obviously, Honda will fix it if you had the tranny fixed 1000 miles ago. Don't worry about it, just make a service appointment and let them take care of it. I'd imagine that a solenoid valve went bad, but maybe the whole tranny needs to be replaced.
