Ram 1500 Transfer Case Shift Motor Dorman 600-908

This is the electric shift motor that bolts to the transfer case on Ram 1500 4x4 trucks from 2011 on, including the Ram 1500 Classic, plus 2013-2018 Ram 2500 and 3500 heavy-duty trucks. When the 4WD switch is moved, the transfer case module powers this motor to rotate the shift shaft into the selected range. It is a new motor with a factory-style sealed connector.

Fits Ram 1500 2011-2015 and 2017-2023, Ram 1500 Classic 2019-2023, Ram 2500 2014-2018, Ram 3500 2013-2018, and Ram 4500/5500 2013-2016. It also covers 2003-2005 Chevrolet Silverado 1500, Suburban 1500 and Tahoe, GMC Sierra 1500, Yukon and Yukon XL 1500, Cadillac Escalade, and 2003-2009 Hummer H2.

Typical failure symptoms: Service 4WD light, the 4WD indicator flashing and not going solid, no response from the 4WD switch, or the truck stuck in 4HI or Neutral. On Rams, water intrusion at the motor plug is a frequent root cause, so seal the connector when you install the new unit.

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.
