Infiniti QX80 Transfer Case Shift Motor 290101LA0A

This is the transfer case shift actuator motor for the 5.6L V8 Infiniti QX56 (2011-2013), QX80 (2014-2020 and 2022) and Nissan Armada (2017-2022). It replaces Nissan 29010-1LA0A and crosses to TDA0010. The unit weighs 3.5 lb.

On these trucks the 4WD mode knob tells the transfer case control unit to drive this motor between 2WD, AUTO, 4H and 4LO. When the motor wears out or its internal position sensor fails, the 4WD warning light comes on, the mode indicator flashes, or the truck will not shift into 4LO. It may also be stuck in one mode.

Scan the transfer case control unit for codes before you order. A code that points to the actuator circuit or actuator position supports replacing the motor. Put the transfer case in 2WD before you remove the old motor. Then match the new motor to the shaft position and do not force it onto the case. Clear the codes afterward and run the truck through every mode to confirm it shifts.
