Index Directions

Diagnosis by Symptom
The Diagnosis by Symptom charts give the technician diagnostic information, direction and possible components of concern, using a symptom as a starting point.
The Diagnosis by Symptom charts are divided into two categories: electrical routines, indicated by 200 series numbers, and hydraulic/mechanical routines, indicated by 300 series numbers. The electrical routines list the possible electrical components that could cause or contribute to the symptom described. The hydraulic/mechanical routines list the possible hydraulic or mechanical components that could cause or contribute to the symptom described.

Diagnosis by Symptom Chart Directions
The Powertrain Control Module (PCM) has a learned adaptive strategy to electronically control the transaxle which will automatically adjust the shift feel to the driver's demands. For the first few hundred miles (160 km) of operation, the transaxle may experience abrupt shifts. This is normal operation.
If the battery has been disconnected for any reason for a period of approximately 20 minutes, the shift tables will reset and will need to be relearned. Upshifting is controlled by the PCM. The PCM receives inputs from various engine and vehicle sensors along with driver demands to control shift scheduling. shift feel, and torque converter clutch operation.
1. Use the index and select the symptom/concern that best describes the condition.
2. Turn to the routine indicated in the index.
3. Always begin diagnosis of a symptom by using the following:
- preliminary inspections
- verification of condition
- fluid level check
- other test procedures as directed

4. Begin with the electrical routine if indicated. Follow the reference or action required statements. Always carry out the On - Board Diagnostic Tests as required. Never skip steps. Repair as required. If the concern is still present after electrical diagnosis, proceed to the hydraulic/mechanical routine listed.

NOTE: Not all concerns and conditions with electrical components will set a diagnostic trouble code (DTC). Be aware that components listed may still he the cause. Verify connect function of those components prior to proceeding to the hydraulic/mechanical routine listed.

5. The hydraulic/mechanical routines list possible hydraulic or mechanical components that could cause the concern. These components are listed in the removal sequence and by "most likely." All components listed must be inspected to verify correct servicing is carried out.
