Autopart International 3403-737398 Transfer Case Shift Motor

The Autopart International 3403-737398 Transfer Case Shift Motor is an aftermarket replacement component designed to restore four-wheel drive functionality in 4WD and AWD vehicles. This electric motor mounts to the exterior of the transfer case and controls the internal shifting mechanism that engages different drive modes.

Key Features:

• Controls transfer case gear engagement for 2WD, 4WD High, and 4WD Low modes
• Electronically actuated shift motor with integrated position sensor
• Direct replacement for worn or failed OEM transfer case motors
• Designed to restore proper 4WD system operation and eliminate warning lights
• Moves selector arms to mesh gears and engage front axle driveshaft

This transfer case motor is essential for vehicles with push-button or switch-activated four-wheel drive systems. When functioning properly, it ensures smooth transitions between drive modes and prevents issues like grinding noises, failure to engage 4WD, or illuminated service lights on the dashboard. The motor also functions as an encoder, sensing and reporting the current position of the transfer case to the vehicle's computer system.

Common Symptoms of Failure: Four-wheel drive not engaging when selected, flashing 4WD indicator lights, "Service 4WD" warning message, grinding or whining noises during mode changes, or inability to shift out of 4WD mode.
