After On-Board Diagnostics

NOTE: The vehicle wiring harness, powertrain control module and non-transmission sensors may affect transmission operations. Repair these concerns first.

After the on-board diagnostic procedures are completed, repair all DTCs.

Repair the non-transmission related DTCs first; then repair any transmission related DTCs; refer to DIAGNOSTIC TROUBLE CODE CHARTS . This chart is helpful in referring to the correct manual(s) or tests, and aids in diagnosing internal transmission concerns and external non-transmission inputs. The pinpoint tests are used in diagnosing transmission electrical concerns. Make sure that the vehicle wiring harness and the PCM are diagnosed as well. The SELF-DIAGNOSTICS - CNG, FLEX-FUEL & GASOLINE article will aid in diagnosing non-transmission electronic components.
