Non-Trouble Code Procedures

After On-Board Diagnostics

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

After the On-Board Diagnostics procedures are completed, repair all DTCs.

Always repair all non-transmission-related DTCs first, then repair any transmission-related DTCs. Refer to the Diagnostic Trouble Code Chart for information on condition and symptoms. This chart will be helpful 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 the PCM are diagnosed as well. TorqShift Automatic Transmission
