Hello and welcome to JustAnswer!

P0731 is for a gear ratio error in first gear, P0732 for second gear. These codes set when the input and output speed sensor signals don't agree for a given gear.

This could be the trans actually slipping in first and second or a speed sensor related issue. A scan tool is really going to be necessary to diagnose the issue. The input and output speed sensor signals will need to be monitored and go from there. You may have a failed speed sensor, a poor connection at one of the sensors, a wiring issue between one of the sensors and the TCM, or you may have gotten two transmissions with internal issues.
