Codes are:

P0420- Air/Fuel ratio, air leak near 02 bank 1, ignition system, faulty catalytic converter

P1739- Automatic transaxle concerns

I accidentally put 89 in it the other day, so I could see that possibly throwing the P0420. Upstream 02 sensor has been replaced in the last year, catalytic converter has been replaced in the last 2 years. Car is running and shifting fine.

Any advice?

420 indicates problem with downstream O2

as far as the transmission goes, they are known for problems in that era Accord

Yeah I'm aware of the transmission issues in the 98-02 models, however I thought that was primarily an issue with the v6 models.

No, its a problem in 4cyl and v6 models. My sister just got rid of hers a while back when the transmission started going out. (2001 2.3L)
