ISSUE
Some 2009-2011 Edge, MKX, Taurus, Flex, MKS and 2010-2011 MKT vehicles built 3/13/2009-6/30/2010 and equipped with a 6F50 or 6F55
transmissions may intermittently exhibit slipping/neutral out, 5th gear start from stop, electronic PRNDL error, backup camera on in Drive or speed
control dropping out intermittently, this may be due to high resistance in the transmission range (TR) sensor.

ACTION
Follow the Service Procedure to diagnose and correct the concern.
