The following items must be checked before proceeding:

Know and Understand the Concern
To account for customer driving habits and conditions, your automatic transaxle electronically controls the shift feel by using an adaptive learning strategy. During the first few hundred kilometers (miles) of operation, it is normal for your transaxle to have abrupt shifts. The adaptive learning strategy is maintained by power from the battery. When the battery is disconnected or a new battery is installed, the transaxle must relearn its adaptive strategy. Optimal shifting will resume within a few hundred kilometers (miles) of operation.

In order to correctly diagnose a concern, first understand the customer complaint or condition. Customer contact may be required in order to begin to verify the concern. Understand the conditions as to when the concern occurs. For example:
- Hot or cold vehicle temperature.
- Hot or cold ambient temperature.
- Vehicle driving conditions.
- Vehicle loaded or unloaded.

After understanding when and how the concern occurs, proceed to verifying the concern.

Verification of Condition
This provides information which must be used in both determining the actual cause of customer concerns and carrying out the appropriate repair procedures.

The following procedures must be used when verifying customer concerns for the transaxle:

Determine Customer Concerns

NOTE: If noise/vibration, check for dependencies: rpm, vehicle speed, shift, gear, range or temperature. Some transaxle conditions may cause engine concerns. The torque converter clutch not disengaging will stall the engine.

- Hot or cold vehicle operating temperature.
- Hot or cold ambient temperature.
- Type of terrain.
- Vehicle loaded/unloaded
- City/highway driving.
- Upshift.
- Downshift.
- Coasting.
- Engagement.
- Noise/vibration - check for dependencies, either rpm dependent, vehicle speed dependent, shift dependent, gear dependent, range dependent, or temperature dependent.
