Ford F-150 Transfer Case Shift Motor Dorman 600-905

This is the electric shift motor on the transfer case of 2015-2020 Ford F-150 4x4 trucks and 2018-2021 Expedition and Navigator 4WD models. When you turn the 4WD selector, the transfer case module drives this motor to move the shift shaft into 2H, 4A, 4H or 4L depending on what the truck is equipped with. It is a new motor with a factory-style sealed connector.

Fits Ford F-150 2015-2020, Ford Expedition 2018-2021, and Lincoln Navigator 2018-2021. It does not fit the 2009-2014 F-150; that generation uses a different motor.

Typical failure symptoms: 4x4 Not Engaged or Service 4x4 message on the cluster, the selector light flashing without the range changing, a grinding or clicking noise from the transfer case area during a shift request, or the truck stuck in 4H or 4L.

Before condemning the motor, check the connector for water and green corrosion, confirm the fuse is good, and check resistance across the motor terminals. An open or shorted winding points at the motor; a good motor with no power points at the harness, switch or transfer case control module. Match the part number on your old motor or the transfer case ID tag before ordering, since these years used more than one case and motor.

On the bench: disconnect the battery, unplug the motor connector, remove the mounting bolts and pull the motor straight off the transfer case shift shaft. Before installing the new motor, note the position of the shift shaft and make sure the socket on the new motor lines up with the shaft flats; do not force it on. Bolt it down, plug it in, reconnect the battery and cycle through 2HI, 4HI, Neutral and 4LO with the engine running to confirm every range light goes solid.
