The recall covers F-150 trucks from the 2011 through 2013 model years with six-speed automatic transmissions.

The company says a glitch in sending a signal from the transmission speed sensor is the cause. Ford has five reports of accidents including one that caused a whiplash injury from a sudden downshift.
