Dodge Ram 600-935 Transfer Case Shift Motor 5143477AA

This is the electric shift motor and encoder that bolts to the outside of the transfer case on electronic-shift 4WD Dodge and Ram trucks. It replaces OE part 5143477AA / 5143477AB and aftermarket 600-935. When you turn the 4WD selector, the module commands this motor to rotate the shift shaft into 2HI, 4HI, N or 4LO, and the encoder tells the module which position it actually reached.

Fits Dodge Ram 1500 and 2500 2006-2010, Ram 3500 2006-2009, Ram 1500/2500/3500/4500 2011-2012, Dodge Dakota 2005-2011, Dodge Durango 2005-2009, Chrysler Aspen 2007-2009 and Mitsubishi Raider 2006-2009. It uses a 7-pin connector. Confirm your truck has the dash-mounted electronic 4WD switch, not a floor shifter, before ordering.

Typical symptoms of a failed motor: Service 4WD message or flashing 4WD indicator, the truck will not go into or come out of 4WD, clicking from the transfer case area when you select a range, or it gets stuck in one mode. Before replacing, check the connector for corrosion and water, and verify the fuse and the transfer case module, since a bad ground or chewed harness produces the same codes.

On the bench: unplug the harness, remove the mounting bolts and pull the motor straight off the shift shaft. Note the shaft position, set the transfer case in the same range the old motor was left in, line up the new motor's socket with the shaft flats, then bolt it on and plug it in. Cycle the selector through every range with the engine running to confirm it engages and the lights stop flashing.
