Answer 1

P1781 OD pressure switch sensor circuit

P1782 2-4 Pressure switch sense circuit

P0731 Gear ratio error in 1st

Go tto the fuse junction box check fuse 15 which is a 20 amp fuse for power make sure it is not open, you may need to replace the transmission control relay. If this is fine go to the solenoid pack inspect your connection to the solenoid pack if they are fine you may have a wrong or skwed solenoid pack.
