P0563 reffers to the vehicles system voltage being high. Thus the headlights getting brighter. Usually caused by a defective voltage regulator built into the alternator. Replacing the alternator is the most common repair. P0700 is a transmission fault code set when something in the transmission control system is at fault. In your case, most likely the control module for the transmission also detected high voltage and put the transmission in limp mode causing the shifting issues you are experiencing. Have the charging system tested and repaired as necessary and the codes rest and the vehicle should go back to normal
Testimonial: "Thank you I am going to go check the charging system now."
