Answer 1

P0743 TCC solenoid circuit

P0750 Shift solenoid A

P0755 Shift solenoid B

P0760 Shift solenoid C

P0765 Shift solenoid D

P1743 EPC solenoid

All these are either open,shorted to ground or disconnected, Theses  have PCM drivers which which can short out at the PCM, Check the harness inside the transmission also on the side where the external part meets at the internal, # thing that can do all this The harness,(which includes connection),The ECM, of the fuse
