Engine management has recently just come on in my 04 st170, got it plugged in to see what was what, codes read are

P0181 - Fuel Temp Sensor A Circuit
P0114 - Engine Coolant Temp Sensor
P0761 - Shift Solenoid C Performance or Stuck off

Just looking for any advice if any one has been through same or similar problems, car runs fine just wanting to look a little more into it and cost? one for always wanting the car to be just right.
Much appreciated.
