Installation Notes and Tips

Verify the vehicle’s cable length, end style, and thread size before ordering. This cable is listed for lower-position and adapter-style applications, and some fitments note cruise control exclusions or THM400-specific use. Inspect the speedometer head, transmission connection, and routing path before installation so the new cable is not forced into a tight bend.

For best results, route the cable smoothly and confirm both threaded connections seat correctly. If the old cable failed from binding, check the housing path and related drive components for wear before installing the replacement.
