What It Helps Address

  • Transmission fluid temperatures that rise during stop-and-go driving

  • Reduced cooling efficiency in a worn or damaged cooler
  • Leaks or connection issues at the factory-style cooler interface
  • Service replacement needs on Jeep Wrangler cooling systems

Installation Notes and Tips

Verify the vehicle’s cooler connection style before installation. This CSF 20042 uses block fitting inlet and outlet tubes, so the replacement should match the existing transmission cooler plumbing on the vehicle. Confirm fitment by year and model before ordering, especially for 2012-2018 Jeep Wrangler and 2018 Jeep Wrangler JK applications.
