Answer 1

P1747 EPC circuit failure short circuit or PCM

P0743 TCC solenoid circuit failure

P0750 Shift solenoid circuit failure

P0755 SSB/SS2 circuit failure

P0141 and P0161  H02S open circuit shorted circuit or grounded

You have a electrical problem or  shorted circuit what does all these code have in common In this diagram listed as (A)  It goes , from the transmission solenoid pack to the H02S check the 02 sensor harness or disconnect the 02 sensor and retest for codes here the diagram From the transmission  solenoid pack the circuit goes to the H02S sensor (A) The first step check the 02 sensor both either one of those shorts out you can expect these code and this condition, and this includes the harness or the 02 sensor Follow Diagram circuit   A . The H02S that is suspectable is the down stream 02 sensor there 2 diagram listed Circuit S127 suspect and correct that
