Ok, both codes are for the governor pressure sensor and solenoid.
You want to first drop the transmission pan and check for debris in the fluid and filter as this will cause the codes.
Next, check the wiring harness to the sensor and solenoid for breaks, cuts, chafing and repair if needed
If above are ok, replace the governor pressure sensor and solenoid. See attachment for their location on the bottom of the valve body. With pan down and filter off, it is just a matter of disconnecting the harness connector to them and unbolting and replacing them
