Your right about the two codes. It's really a transmission part.
As soon as you open up the transmission pan, it right there.
But, I would leave this up to a transmission place. It may need a special type of calibration tool for the new sensor.
As for PO303, that is a missfire in cylinder #3
I hope I answered your question.
