ISSUE
Some 2007-2010 Expedition, 2009-2010 Navigator and F-150 vehicles equipped with a 5.4L engine and a 6R75/6R80 transmission may exhibit delayed forward/reverse engagement. Diagnostic trouble codes (DTCs) P0741, P0731, and/or P0735 for torque converter and/or gear ratio concerns may be stored in the powertrain control module (PCM). This concern typically occurs after cold start and in colder climates.
