Code 19 is "A/T Lockup control solenoid" caused by "Open or shorted signal circuit, lockup solenoid" and code two is "Oxygen sensor circuit" that can be a complaint with the O2 sensor output.
This is a good time to replace the O2 sensor, if only because it's 14 years old and now there's a trouble code.
The lockup solenoid is going to take some troubleshooting, but my guess is the solenoid itself is bad. They aren',t a high failure rate item but they have been recognized to fail.
