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

After the on-board diagnostic procedures are completed, repair all DTC's.

Begin with non-transmission related DTC's, then repair any transmission related DTC's. Refer to the Diagnostic Trouble Code Charts, for information on condition and symptoms.
