Detailed Product Information
SKP SK600903 is a replacement transfer case motor that moves the transfer case between drive modes when the shift system is commanded from the cabin.

This unit is built for NP8-equipped New Process 226 transfer cases and matches the 7-pin rectangular connector used on the listed applications. This part cross-references 600903 for the same application.
What This Part Helps Resolve
- Inability to switch between 2WD and 4WD
- Delayed or incomplete transfer case engagement
- Transfer case shift motor failure codes
- Intermittent four-wheel drive operation
