i'd check out your local part stores and junk yards, but your not going to get anything from these guys close to it's retail value, the only way to get that would be to sell it to someone who needs it. so best bet for more than say 100-200 dollars for all your parts would be Ebay. even then an auto tranny would be hard to sell unless someone blew theirs and needed a replacement, the ecu, maybe if it's a non '02 for people wanting to do the rev limiter upgrade, but I've seen the ecu go for about 50 bucks.
