WARNING: This page is about a different car, the 2013 Ford F-550 Super Duty, 2013 Ford F-450 Super Duty, 2013 Ford F-350 Super Duty, and 2013 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The vehicle wiring harness, PCM and non-transmission sensors can affect transmission operations. Repair these concerns first.
After the OBD procedures are completed, repair all DTCs.
Always repair all non-transmission related DTCs first, then repair any transmission related DTCs. Refer to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS for information on condition and symptoms. This chart is helpful in referring to the correct manual(s) and to aid in diagnosing internal transmission concerns and external non-transmission inputs. Use the pinpoint tests to diagnosis transmission electrical concerns. Make sure the vehicle wiring harness and the PCM are diagnosed as well. The INTRODUCTION - DIESEL MODELS or ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) aids in diagnosing non-transmission related electronic components.
