Verification of Condition

Verification of Condition
This section provides information which must be used in both determining the actual cause of customer concerns and carrying out the appropriate procedures. The following procedures must be used when verifying customer concerns for the transaxle.

Determine Customer Concern

Note: Some transaxle conditions may cause engine concerns. An Electronic Pressure Control (EPC) short circuit can cause engine misfiring. The torque converter clutch not disengaging will stall the engine.

Determine customer concerns relative to vehicle use and dependent driving conditions, paying attention to the following items:
- hot or cold vehicle operating temperature
- hot or cold ambient temperatures
- 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.

Note: Always check fluid levels prior to Road Test.

For Road Test procedures, refer to Road Tests under Transaxle Testing and Inspection Procedures. Shift Point Road Tests
