SYMPTOM TROUBLESHOOTING CHART-AUTOMATIC TRANSMISSIONDiagnosis by Symptom Chart Directions
1. Using the Symptom Index, select the symptom that best describes the condition.
2. See the action indicated in the Diagnosis by Symptom Index.
3. Always begin diagnosis of a symptom with:
^ Preliminary inspections.
^ Verifications of condition.
^ Checking the fluid levels.
^ Performing other test procedures as directed.
Caution:
^ Not all concerns and conditions with electrical components will set a diagnostic trouble code (DTC). Be aware that the components listed may still be the cause.
Note:
^ The powertrain control module (PCM) has an adaptive learning strategy to electronically control the transmission which will automatically adjust the shift feel. When the battery has been disconnected, or a new battery installed, certain transmission parameters may be lost. The PCM must relearn these parameters. During this learning process you may experience slightly firm shifts, delayed, or early shifts. This operation is considered normal and does not affect the function of the transmission. Normal operation returns once these parameters are stored by the PCM.
