TSB 10-12-4 5.4L 3V and 6R80 transmission - Delalyed/harsh downshift above 40 mph

FORD: 2009-2010 Expedition, F-150
LINCOLN: 2009-2010 Navigator


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 engine and 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.

The service procedure basically is a reprogram of the TCM.

Look on your drivers door or the cab for a sticker that will have it, plus other codes or you can look at your SVT cert.

even if the truck was built after that date of the TSB and you tell the dealer the truck is shifting hard or delayed and you show them the TSB, they should reflash it.....

I watched birds vid, and my second lag back to back numerous times. The lag is slightly shorter, the biggest difference was the speed from 40 to 50 between the two.
