I have a u0073 and u0100 code what can the cause and repair be?

Question

Car runs fine until this occurs. When accelerating from a stop the at light and tcs off light came along with the swerving vehicle picture light. Car would barely run and acted as if the transmission was locking up. I then put it in park turned off the ign. then restarted and everything was back to normal. These codes were pulled up by someone with a OBD11 scanner.
