2005 Nissan Pathfinder Transmission Transfer Case Motors

The 4WD transfer case on certain Nissan Armadas and Pathfinders is lubricated by a recirculating oil pump with a DC motor that’s prone to failure after only a few thousand hours, resulting in driveline noise and ultimately, a failed transfer case. That premature – and costly – failure often occurs when the brushes in the transfer case’s original equipment DC motor burn out, shutting down the pump that keeps the transfer case lubricated. This Dorman OE FIX transfer case oil pump uses a brushless DC motor instead of a brushed motor, eliminating the typical cause of failure. And because the brushless DC motor is rated to last tens of thousands of hours rather than a few thousand, future costs to service the transfer case can be significantly reduced. This upgraded pump design is designed and built to last, and has undergone testing for vibration, salt spray and dust and water resistance, as well as thermal cycling, electrical, and mechanical reliability testing.

Product Features:

• Upgraded design – this transfer case oil pump features a long-life brushless DC motor instead of the brushed DC motor on the original equipment pump, which can fail after just a few thousand hours of use
• Saves expense – the brushless DC motor in this pump is rated for tens of thousands of hours, decreasing the frequency of costly service intervals required for the OE DC brushed motor
• Rigorously tested – this pump has undergone testing for resistance to vibration, water, dust, and salt spray, and for thermal cycling, electrical and mechanical reliability
• Trustworthy quality – backed by team of engineers and inspectors in the United States
