Index Directions

The 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 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 released. Upshifting is controlled by the Powertrain Control Module (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 be the cause. Verify correct 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.
