ISSUE
Some 2005-2006 Five Hundred and Montego vehicles equipped with Aisin six speed transmissions and built prior to 10/17/2005 may experience shift concerns when the vehicle mileage gets above 20,000 miles (32,187 km). Shifting concerns are generally noticed during passing maneuvers with transmission 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 DTCs are present in the transmission control module (TCM) / powertrain control module (PCM), perform normal diagnostics. Refer to Workshop Manual (WSM), Section 307-01B.
2. If no DTCs are present and mileage is below 20,000 miles (32,187 km) reprogram TCM / PCM and retest.
3. If no DTCs are present and mileage is over 20,000 miles (32,187 km), fluid should be drained and checked for excessive contamination. If fluid is clean, 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.
4. If excessive contamination is present, install a new transaxle assembly following normal prior approval guidelines.
Reprogramming
Reprogram the PCM and TCM to the latest calibration using IDS release 45.8 and higher. Calibration files may also be obtained at the website.
