ISSUE
Some 2009 Explorer, Mountaineer and Explorer Sport Trac vehicles equipped with a 6R80 transmission and built prior to 10/1/2008 may exhibit a bump
feeling while braking to a stop below 15 MPH (24 Km/h) and some vehicles a harsh 1-2 upshift. A later calibration is available to improve these
conditions.
ACTION
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
1.
Install Integrated Diagnostic System (IDS)/Portable Diagnostic Software (PDS) or equivalent and start a session, identify (ID) vehicle.
2.
Update the powertrain control module (PCM)/transmission control module (TCM) calibration using IDS release 62.11 and higher. This new
calibration is included in the VCM 2009.7 DVD. Calibration files may also be obtained at the website.
The TCM cannot be independently reprogrammed. Reprogram using the programmable module installation (PMI) function to ensure that engine and
transmission calibrations are updated to the latest level simultaneously.
In some cases it maybe helpful to
^
Disconnect the TCM connector.
^
Start a new IDS session.
^
Perform PMI on the PCM.
^
Once IDS instructs to install the new module in the vehicle, plug the TCM in and follow the prompts.
a. Verify that the TCM calibration shows 9L2P-7J104-AG part number after reprogramming is complete.
b. Select the following from the IDS tool:
(1) Toolbox.
(2) Powertrain.
(3) OBD Test Modes.
(4) Mode 9 Vehicle Information.
(5) TCM Cal Part Number.
3.
Clear TCM keep alive memory (KAM) and adaptive tables.
a. Using IDS:
(1) Open Toolbox.
(2) Choose Powertrain.
