Before Performing Tests

Note:
^ Prior to entering test procedures, check the PCM wiring harness for proper connections, bent or broken pins, corrosion, loose wires, proper routing, proper seals and their condition. Check the PCM, sensors and actuators for damage.

Note:
^ If a concern still exists after electrical diagnosis has been performed, see Diagnosis by Symptom. See SYMPTOM TROUBLESHOOTING CHART-AUTOMATIC TRANSMISSION. Symptom Troubleshooting Chart-Automatic Transmission

If DTCs appear while performing the on-board diagnostics, see the Diagnostic Trouble Code Index for the appropriate repair procedure. See DTC INDEX-AUTOMATIC TRANSMISSION. Diagnostic Trouble Code Descriptions
