P0763 Problem in shift solenoid valve C circuit
When you set a shift solenoid code you will set a P0710 code, This would not be a faulty transmission, well just not yet hopefully,Faulty transmission are internal mechanical problem like P0740 TCC circuit or solenoid which is always internal hydraulic problems or gear shift error codes, For the shift solenoid you are either missing power or ground, Use this diagram make a new wire to your circuit to the ECM and bridge a circuit for its ground and retest, you have wiring problem
