This is the most common failure that will cause this code. COPY & PASTE THE LINK. Look at photo #22, the purge control solenoid. http://www.justanswer.com/questions/2gyog-code-po441-honda-accord-1997-fix
Depends on what the problem is. One warning I can provide. Use only genuine Honda ATF fluid in your Accord. The use of any other fluid will cause problems. I suggest you seek out a professional to repair the transmission.
I am sorry to say that there is no answer to this question. Just do a general search on 2007-08 -09 Honda accord headlight problems and you will see that Honda is ignoring the problem but there has been a couple of buyback orders if you look on the Honda-tech forums under headlight problems. sorry
