Maybe one of the wires to the rt side O2 sensor got broken or pinched during the tranny swap. If not, I think you should be able to get a decent O2 sensor at most part stores...I believe that the Bosch ones are just as good if not better than OEM (OEM might even be Bosch??)

the o2 wasnt plugged in. dont know why it was unplugged, but anyway. i think its all better now. hasnt thrown any codes yet, and i drove around town for about an hour doing errands.
