After OBD

WARNING: This page is about a different car, the 2012 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The vehicle wiring harness, TCM and non-transmission sensors may affect transmission operations. Service these concerns first.

After the OBD procedures are complete, service all DTCs.

Begin with non-transmission related DTCs, then service any transmission related DTCs . Refer to the DIAGNOSTIC TROUBLE CODE (DTC) CHARTS for information on condition and symptoms. This chart is helpful referring to the correct manual(s) and to aid in diagnosing internal transmission concerns and external non-transmission inputs. The pinpoint tests are used in diagnosing electrical concerns of the transmission. Make sure the vehicle wiring harness and TCM are diagnosed as well. REFER to INTRODUCTION - GASOLINE MODELS for diagnosing non-transmission electronic components. The diagnostic routine hydraulic/mechanical charts will help in diagnosing internal transmission concerns and external non-transmission inputs.
