When the OD light starts blinking, that would indicate a fault in the transmission control system and it can cause shifting irregularities. Trouble codes should be present though it might take a while for it to come back after clearing the codes.
What was the trouble code retrieved? Get a scan done again and let me know the present trouble code. There should be one snce the OD light had started blinking after clearing the codes.
