Pulled engine to fix rear main seal now code PO753 and PO133. Probably electrical connections?

Question

Check engine light on after repair rear main seal

Answer 1

P0753 Transmission 3-4 solenoid,/ transmission relay circuit

P0133 Bank 1 sensor 1 slow response

It possible that this is the connection to the transmission , Inspect the connection going into the transmission look for push out pins or bent pins. Then go to the Engine fuse/relay use the fuse cover as a map swap the transmission control realy and check fuse 17. P0133 look and inspect the MAF (mass airflow )air duct tube that may have come loose, If everything is secured, This may of happen when the battery was disconnected, When the battery is disconnected the long trim fuel trim is erased from memory, All its adaptive strategy is to be relearned. This includes the tranmission shift points.Having a slow 02 sensor mean it is degraded, 3-4 shift solenoid could just be faulty.Also check the charging system .
