This article supersedes TSB 08-23-16 to update the vehicle lines and issue statement.
ISSUE
Some 2008-2009 Taurus, Taurus X, Sable vehicles built before 10/15/2008, and 2008-2009 Edge and MKX vehicles built before 11/20/2008 may exhibit a harsh driveline clunk at low speed, below 10 MPH (16 Km/h) during stop and go driving on tip-in may be due to a Powertrain Control Module (PCM) calibration. There is a new calibration that will improve the low speed stop and go driving feel.
ACTION
Reprogram the PCM to the latest calibration using IDS release 57.10 and higher or 58.1 and higher. This new calibration is not included in the VCM 2008.11 DVD. Calibration files may also be obtained at the website.
NOTE
THIS NEW CALIBRATION WAS IMPLEMENTED IN PRODUCTION ON OCTOBER 15, 2008 FOR THE 2009 MODEL YEAR TAURUS, TAURUS X, SABLE VEHICLES, AND ON NOVEMBER 20, 2008 FOR THE 2009 MODEL YEAR EDGE, MKX VEHICLES, THIS PROCEDURE DOES NOT APPLY TO ANY VEHICLE BUILT AFTER THOSE DATES.
