PRELIMINARY
1. Visually inspect the automatic transaxle from above and below the vehicle:

- Fluid leaks
- Loose engine or transaxle support insulators
- Front wheel driveshaft joint loose, worn or damaged
- Gearshift lever linkage worn or damaged
- Excessive wear or damage to front brakes

- Stretched, open or damaged wiring harness
- Corroded or loose connectors
- Non-factory installed electrical equipment
2. Check the accelerator pedal linkage for freedom of travel.
3. Shift the gearshift lever manually through all ranges to check for ease of movement, obvious binding, or incorrect adjustment.
4. Drive the vehicle to verify the customer complaint if possible.
5. Request the customer to road test the vehicle with the technician for intermittent concerns with the automatic transaxle.
6. If no fault is visually evident, proceed to Check Fluid Level and Condition.
KNOW/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, proceed to verifying the concern.
VERIFICATION OF CONDITION
Before verifying the condition, proceed to the Check Fluid Level and Condition. Check for leaks.
NOTE: Some transmission conditions may cause engine concerns. The torque converter clutch not disengaging will stall the engine.
