Ford F-150 Shift Interlock Solenoid 924-972

This is the brake shift interlock solenoid for the 2011-2018 Ford F-150, the 2011-2016 F-250, F-350, F-450 and F-550 Super Duty, and the 2015-2017 Expedition with the automatic transmission. It replaces aftermarket number 924-972 and Ford 7L1Z-3Z719-A, and the listing also references BC3Z-3Z719-A, CC3Z-3Z719-B, CC3Z-3Z719-C, FL3Z-3Z719-A, FL3Z-3Z719-B and FL3Z-3Z719-C. It has a metal and plastic housing with a 4-terminal connector and plugs into the factory harness. This is a different part from the 2004-2014 F-150 BTSI actuator (609-039), so match your truck's year before ordering.

The interlock solenoid holds the column shifter in Park until the brake pedal is pressed. When it fails, the usual complaint is a shifter that will not come out of Park even with the brake pedal down and the brake lights working. It can also fail the other way and let the shifter leave Park without the brake. A solenoid that clicks with no release, or a shifter that only releases some of the time, points to this part. Check the brake lights and the brake pedal switch first, because the solenoid only releases when it gets the brake signal.

To move the truck in the meantime, use the shift lock override. To replace it, disconnect the battery, remove the steering column shrouds, unplug the old solenoid, remove its mounting screw and note how the wiring is routed. Install the new solenoid in the same position, route the wiring the same way, reconnect, and test that the shifter stays locked in Park without the brake and releases every time with it.
