P1747 - Electronic Pressure Control Solenoid - Short circuit
P0755 - Shift Solenoid 'B' Malfunction
P0743 Torque Converter Clutch (TCC) Solenoid Circuit Electrical
Before you changed the shift solenoid, you had the same errors? Short circuit could happen because of broken shift solenoid. Could also be an electrically error in EPC.
I had the same problem. It turned out to be a 15a fuse under the hood. The transmission fuse. As soon as i changed the fuse it ran like before.
