Common Problems This Part Can Address

• Transmission fluid leaks from a rusted or damaged cooler hose
• Restricted fluid flow caused by a collapsed or kinked line
• Corrosion on the original steel tubing
• Improper routing after a previous repair
• Heat-related deterioration of the hose section

Installation Notes and Tips

Confirm the end fittings and routing before installation on your Dodge Ram 2500 or Dodge Ram 3500. Inspect the mating connections, brackets, and surrounding components for wear or corrosion, and verify that the line follows the factory lower transmission-to-radiator path. The pre-bent design is intended to simplify alignment with the original vehicle layout.
