ISSUE
Some 2011-2012 Escape, Fusion, 2011 Mariner and Milan vehicles built on or before 5/8/2012 and equipped with a 6F35 transmission may exhibit an intermittent harsh 1-2 shift or harsh 5-6 shift regardless of temperature or soak time. Additionally, 4-5 shift flare may be experienced after an extended cold soak on the first few 4-5 shifts of the day. 2.5L equipped vehicles with late 4-5 shift events and/or high RPMs being experienced may also benefit from this calibration update.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1. Reprogram the powertrain control module (PCM) to the latest calibration using Integrated Diagnostic System (IDS) release 78.02A and higher. This new calibration is not included in the VCM 2012.3 DVD. Calibration files may also be obtained at the website.
2. Verify that the transmission fluid level is at the top of the operating range if vehicle is not used for recreational flat towing behind a motorhome at a transmission fluid temperature of 85 °C (185 °F).
NOTE
PLEASE ADVISE THE CUSTOMER THAT THIS VEHICLE IS EQUIPPED WITH AN ADAPTIVE TRANSMISSION SHIFT STRATEGY WHICH ALLOWS THE VEHICLE'S COMPUTER TO LEARN THE TRANSMISSION'S UNIQUE PARAMETERS AND IMPROVE SHIFT QUALITY. WHEN THE ADAPTIVE STRATEGY IS RESET, THE COMPUTER WILL BEGIN A RE-LEARNING PROCESS. THIS RE-LEARNING PROCESS MAY RESULT IN FIRMER THAN NORMAL UPSHIFTS AND DOWNSHIFTS FOR SEVERAL DAYS.
