P0713 P1788

P0713 is for the temp sensor and the P1788 is for the pressure control solenoid B, both are within the solenoid block assembly.

I would inspect the connection at the case connector for corrosion or missing or bent pins, if all ok I would suspect the solenoid block itself.

Check for debris in the pan before buying anything.
