Ford Ranger Transfer Case Shift Motor 600-931 7-Pin

This is the electric shift motor that bolts to the rear of the transfer case on 2006-2011 Ford Ranger 4WD pickups and drives the shift rail between 2WD, 4x4 High and 4x4 Low. It replaces Ford OE numbers 6L5Z-7G360-AA, 6L5Z-7G360-AB and 6L5Z-7G360-AC, and it is the same unit sold as Dorman 600-931. It uses the 7-pin connector, so check your harness before ordering - Ranger transfer cases were built with more than one plug and the styles are not interchangeable.

Fitment is Ranger 2006-2011 with the 2.3L four, 2006-2008 with the 3.0L V6 and 2006-2011 with the 4.0L V6, all pickup bodies running the 7-pin motor. The motor carries both the drive gear and the encoder contacts that tell the 4WD module where the shift rail actually sits, which is why a bad one takes the dash indicator down with it.

The symptoms that point here are a 4x4 light that blinks and never stops, a truck that will not leave 2WD when you turn the dash switch, or one that engages 4x4 and refuses to come back out. Corrosion is the usual cause: the motor lives under the truck right in the salt spray, water gets past the housing seal, and the encoder contacts inside go green. Before you condemn it, check the 4WD fuse and confirm the motor is getting battery voltage at the connector when the switch is moved, because a chafed harness up the frame rail gives the same no-shift complaint.

Installation is four bolts on the back of the case and one connector. Support the motor as you pull it so the shift rail stays where it belongs, line up the drive gear on the rail before you seat the housing, and torque the bolts evenly so you do not crack the plastic. Cycle the switch through High, Low and back to 2WD with the truck rolling slowly before you call it done.
