Preliminary Inspection





NOTICE: The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage. Refer to the Material specification and/or the transmission fluid level indicator for the correct fluid. Use only clean transmission fluid designated for this transaxle and torque converter being serviced.

NOTICE: Do not mix Mercon(R) V or Mercon(R) LV transmission fluid. This may cause erratic shift feel, erratic shift timing and/or transmission failure.

NOTE: Transmission fluid application:
- Early build vehicles require MERCON(R) V
- Late build vehicles require MERCON(R) LV

The following items must be checked prior to beginning the diagnostic procedures.

Verification of Condition

This 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 transmission.

Determine Customer Concern

NOTE: Some transaxle conditions may cause engine concerns. An electronic pressure control short circuit can cause engine misfiring. The Torque Converter Clutch (TCC) 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.
