as when in a traffic jam. Additionally some 2007 Expedition vehicles may exhibit a harsh 1-2 shift and/or 2-1 downshift, 1-2 shift flare, and/or long
engagement time.
ACTION
Reprogram the powertrain control module (PCM) and transmission control module (TCM) to the latest calibration using IDS release 47.6 or higher and
48.1 and higher. This new calibration is not included in the VCM 2007.3 DVD. Calibration files may also be obtained at the website.
