Verification of Condition
PRELIMINARY INSPECTIONThe following items must be checked before proceeding:
KNOW AND UNDERSTAND THE CONCERN
In order to properly diagnose a concern you must first understand the customer complaint or condition. Customer contact may be required in order for the technician to begin to verify the concern. You must understand the conditions as to when the concern occurs. For example:
- hot or cold vehicle temperature
- hot or cold ambient temperature
- vehicle driving conditions
After understanding when and how the concern occurs then proceed to verifying the concern.
VERIFICATION OF CONDITION
Verification of Condition provides information which must be used in both determining the actual cause of customer concerns and performing the appropriate service procedures. The following procedures must be used when verifying customer concerns for the AX4S transaxle:

- Transmission Range (TR) Sensor Alignment Tool (MLPS Alignment Tool) T92P-70010-AH
DETERMINE CUSTOMER CONCERN
- 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
NOTE:
- If noise/vibration, check for dependencies, either rpm dependent, vehicle speed dependent, shift dependent, gear dependent, range dependent or temperature dependent.
- Some AX4S transaxle conditions may cause engine concerns. The torque converter clutch not disengaging will stall the engine.
CHECK TSBs
Refer to all technical service bulletins which pertain to the transaxle concern and follow the procedure.
PERFORM ON-BOARD DIAGNOSTICS
