Repair Verification

After making a repair to the transaxle, it is important the repair is verified before returning the vehicle to the customer. The vehicle must be driven so that each upshift and downshift is accomplished at least twice, and then the PCM must be checked for DTCs. Not all faults will illuminate an indicator lamp and the memory must be checked using a scan tool.
