TSB 10-12-4
ISSUE:
Some 2009-2010 Expedition and Navigator vehicles built on or before 5/1/2010 and 2009-2010 F-150 vehicles built on or before 2/1/2010 and equipped with 5.4L 3V engineand 6R80 transmission may exhibit a delayed then harsh downshift during a commanded downshift at speeds above 40 MPH (64 Km/h).
ACTION:
Follow the Service Procedure to correct the condition.
SERVICE PROCEDURE
1. Install Integrated Diagnostic System (IDS)/Portable Diagnostic Software (PDS) or equivalent and ID vehicle.
2. Reprogram the powertrain control module (PCM)/transmission control module (TCM) calibration using IDS release 67.03 and higher. This new calibration is not
included in the VCM 2010.5 DVD. Calibration files may also be obtained at
www.motorcraft.com.
a. Verify that the TCM Calibration is:
1. AL3P-7J104-AC for all vehicles except the F-150 4X4.
2. AL3P-7J104-BC for F-150 4X4.
b. Select the following from the IDS tool:
1. Toolbox
2. Powertrain
3. OBD Test Modes
4. Mode Level 9 Vehicle Info
5. TCM Cal Part Number
3. Clear TCM keep alive memory (KAM) and adaptive tables.
a. Using IDS:
1. Open Toolbox
2. Choose Powertrain Then Choose TCM
3. Choose Reset KAM
b. Using PDS:
1. Choose all Tests and Calibrations
2. Scroll down the menu and choose reset TCM KAM
4. Verify that the transmission fluid temperature (TFT) PID is above 175 °F (80 °C). If it is not at 17 5 °F (80 °C), drive unit approximately 3 miles (5 K m) to reach
temperature.
5. Drive unit to perform adaptive shift strategy learn.
a. Accelerate from a stopped position with light throttle to 15 MPH (24 Km/h) and remove foot from accelerator pedal.
b. Brake very gently to a complete stop, allow at least six (6) seconds.
c. Repeat steps (a-b) five (5) times in the dealership parking lot or similar setting.
d. 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.
e. Continue to accelerate until you achieve 50 MPH (80 Km/h) or the 5-6 upshift.
f. Brake gently to a complete stop and hold foot on brake for ten seconds.
g. Repeat steps (d-f) three (3) times.
FORD: 2009-2010 Expedition, F-150
LINCOLN: 2009-2010 Navigator
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.
NOTE: IT IS CRITICAL THAT TCM KAM BE CLEARED FOR THIS PROCEDURE TO BE FULLY EFFECTIVE
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.
NOTE: TFT MUST BE AT 175 °F (80 °C) OR ABOVE BEFORE PROCE EDING TO STEP 5.
NOTE: PERFORM ADAPTIVE SHIFT STRATEGY LEARN ON LEVEL SURFACE ROAD.
NOTE: SEVERAL DAYS OF DRIVING ARE REQUIRED FOR THE TRANSMISSION TO FULLY ADAPT.
