Publication Date: May 25, 2009

FORD: 2009 F-150


ISSUE:
Some 2009 F-150 vehicles equipped with 5.4L 3V engine and equipped with a 6R80 automatic transmission may exhibit the following symptoms during warm-up: a harsh 1-2 upshift, harsh 2-1 downshift while coasting 15 MPH (24 Km/h). A harsh downshift into 4th gear at highway speeds 45-70 MPH (72-113 Km/h) may also be experienced. Some vehicles may have a diagnostic trouble code (DTC) P0741 torque converter performance code present or stored.

ACTION:
Follow the Service Procedure to correct this condition

SERVICE PROCEDURE

NOTE: DO NOT ATTEMPT TO REPLACE THE MECHATRONIC UNIT. MECHATRONIC REPAIR/REPLACEMENT IS NOT AUTHORIZED FOR THIS ISSUE.



Install IDS/PDS or equivalent and ID vehicle.
Update the powertrain control module (PCM)/transmission control module (TCM) calibration using IDS release 60.14 and higher or 61.04 and higher. This new calibration is not included in the VCM 2009.5 DVD. Calibration files may also be obtained at www.motorcraft.com.
NOTE: THE TCM CANNOT BE INDEPENDENTLY REPROGRAMMED, REPROGRAM USING THE PMI FUNCTION TO ENSURE THAT ENGINE AND TRANSMISSION CALIBRATIONS ARE UPDATED TO THE LATEST LEVEL SIMULTANEOUSLY.



Verify that the TCM Calibration shows AL3P-7J104-AB (4x2) or AL3P-7J104-BB (4x4) part number after reprogramming is complete by selecting the following from the IDS tool.
Toolbox
Powertrain
OBD Test Modes
Mode Level 9 - Vehicle Information
TCM Cal Part Number
NOTE: IT IS CRITICAL THAT TCM KAM BE CLEARED FOR THIS PROCEDURE TO BE FULLY AFFECTIVE.



Clear TCM keep alive memory (KAM) and adaptive tables
Using IDS:
Open Toolbox
Choose Powertrain
Choose Reset KAM
Then Choose TCM
Using PDS:
Choose all Tests and Calibrations
Scroll down the menu and choose reset TCM KAM
NOTE: FOR PDS, RESET TCM KAM IS NOT THE SAME AS CLEAR TRANSMISSION ADAPTIVE TABLES, WHICH IS UNDER THE POWERTRAIN - TRANSMISSION MENU TREE.



NOTE: UNHOOKING THE BATTERY WILL NOT CLEAR THE TCM KAM. IT IS CRITICAL THAT TCM KAM BE CLEARED PRIOR TO RELEARNING THE ADAPTIVE TABLES FOR THE TRANSMISSION.



NOTE: DO NOT CLEAR THE PCM KAM.



Verify that the transmission fluid temperature (TFT) PID is above 175 °F (80 °C). If it is not at 175 °F (80 °C), drive unit approximately 3 miles (5 Km) to reach temperature.
NOTE: TFT MUST BE AT 175 °F (80 °C) OR ABOVE BEFORE PROCEEDING TO STEP 5.



NOTE: PERFORM ADAPTIVE SHIFT STRATEGY LEARN ON LEVEL SURFACE ROAD.



Drive unit to perform adaptive shift strategy learn.
Accelerate from rest with light throttle to 15 MPH (24 Km/h), remove foot from accelerator pedal.
Brake very gently to a complete stop (allow at least six (6) seconds).
Repeat steps (a-b) five (5) times in the dealership parking lot or similar setting.
Accelerate from rest with light throttle ensuring that the 1-2, 2-3 and 3-4 shifts occur at engine speeds between 1700-2000 RPM.
Continue to accelerate until you achieve 50 MPH (80 Km/h) or the 5-6 upshift.
Brake gently to a complete stop and hold foot on brake for ten seconds.
Repeat steps (d-f) three (3) times.
NOTE: SEVERAL DAYS OF DRIVING ARE REQUIRED FOR THE TRANSMISSION TO FULLY ADAPT.
