Detailed Product Overview

This Dorman transfer case motor is designed for Toyota 4Runner and Toyota Tacoma applications where the transfer case no longer shifts properly between 2WD and 4WD ranges. Part number 600-423 matches the original style of the vehicle’s transfer case actuator setup, helping restore normal range selection without changing the factory connection layout. It is a practical replacement for a seized or worn transfer case motor on 2020-2023 Toyota 4Runner models without the Limited Package and 2016-2023 Toyota Tacoma models.

The unit uses a rectangular connector, blade terminals, and a bolt-on mounting design with three mounting holes. The plastic housing is sealed to help protect internal components from exposure under the vehicle. Dorman 600-423 is built for direct replacement service where the original transfer case motor has failed and the drivetrain will not shift as expected.

What It Helps Fix

• Transfer case stuck in high range
• Transfer case stuck in low range
• Failure to shift between 2WD and 4WD modes
• Seized or inoperative transfer case motor
• Intermittent range-selection problems on the transfer case
