Codes P1744 and P0457 but there is nothing worng runs fine

Code P0457 indicates that the Fuel Cap is off, so start by checking the fuel cap. Make sure that it is very tight. the P1744 is a bit more complicated, it has to do with the Torque Converter Clutch slipping for your Transmission. You may not feel anything out of the ordinary, but the light will stay or keep coming on until the Torque Converter Clutch is addressed by a good Transmission Shop. http://repairpal.com/ford-repair-in-lampasas-texas
