Dorman – Help – Transmission Shift Cable Repair (Part No.74021)

Transmission Shift Cable Repair

from

  • Simple installation – the steel end joint in this patented repair kit features an innovative split and threaded ferrule design that installs quickly and easily on the factory cable end
  • Restores shifting – this kit is designed to help ensure precise, reliable automatic transmission shifts on specified Toyota, Lexus, and Scion vehicles
  • Trustworthy quality – backed by a team of product experts in the United States and more than a century of automotive experience
