ISSUE
Some 2005-2007 Five Hundred, Montego, and 2006-2008 Fusion, Milan, 2006 Zephyr and 2007-2008 MKZ vehicles equipped with an Aisin automatic transmission may experience shift concerns when the vehicle mileage gets above 20,000 miles (32,200 km). Shifting concerns are generally noticed during passing maneuvers with transmission at temperatures greater than 212 °F (100 °C) operating temperatures. Symptoms may be present during downshift 5-3 at 35 MPH (56 km/h) and/or 4-3 at 20 MPH (32 km/h) with throttle opening at approximately 50% or greater and include:

^ Harsh shift and/or clunk noise

^ Delayed shift and/or perceived slip/engine flare

ACTION
Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

1. If diagnostic trouble codes (DTCs) are present in transmission control module (TCM) / powertrain control module (PCM), do not continue with this procedure. Perform normal diagnostics. Refer to Workshop Manual (WSM), Section 307-01B

2. If no DTCs are present and mileage is below 20,000 miles (32,200 km) reprogram TCM / PCM and retest.

3. If no DTCs are present and vehicle is over 20,000 miles (32,200 km), fluid should be drained and checked for excessive contamination. If fluid is not burnt, the valve body should be replaced and TCM / PCM updated to the latest calibration level. Refer to WSM, Section 307-01B for main control valve body replacement.
