Some 2013-2014 Lincoln MKZ vehicles may shift to Park when the vehicle is travelling below 5 mph and/or may exhibit a wrench light illuminated with DTC P081F stored in the gear shift module (GSM).
Reprogram the PCM and the GSM to the latest calibration using IDS release 86.03 and higher. The push-button shift transmission has unique operating characteristics including an automatic return to Park feature.
Refer to the owner’s manual (transmission section) for expected system operation.
