I just replaced the transmission on my 2002 Honda Accord. I seems the radio and clock were reset as a result. There is an error message on the radio along with a count of how many times I tried to guess the code. There is no code in the manual. How do I get the code?

Code may be hand written in the owners manual, on a sticker in the manual, on a sticker in the glove box or on a sticker in the trunk. If not anywhere then pull the radio, get the serial number and proof that you own the car and give this info to the dealer, don't let them charge you to reset the radio.

If you don't get the serial number, then they WILL charge you. Next time you need to disconnect the battery get a 'keep alive' battery connector to put in the cig lighter socket.
