It might be best to buy another car now. Even though you've taken good care of the engine, you have to guess whether it will need a timing belt or new head gasket etc, both expensive repairs. The problem in my opinion is that the only good automatic transmission worth the money is a new "remanufactured" transmission (NOT a "rebuilt" transmission) from a company like http://www.jasperengines.com or your Honda dealer etc. But that would cost at least $3000. So the bottom line is that I don't recommend you investing any more money in this car, even if you lose your $3000 investment!
