Why This Hose Matters
This Dorman 624-544 transmission line is built to restore fluid transfer between the transmission and the cooler circuit when the original hose is damaged, leaking, or no longer sealing properly. The molded metal-and-rubber design supports a stable connection at the lower radiator cooler return tube while maintaining the flexibility needed for routing in the engine bay. It is a practical replacement for Dodge Ram 1500, Ram 2500, and Ram 3500 trucks that use the lower return tube and hose from the lower radiator cooler to the transmission.
Common Problems It Can Address
- Transmission fluid leaks at the cooler hose connection
- Cracked, corroded, or deteriorated cooler line sections
- Loose or unreliable sealing at the quick-disconnect end
- Restricted fluid transfer caused by a damaged hose assembly
- Replacement needs after failure of the lower return tube and hose assembly
Installation Notes
Verify the vehicle uses the lower-position return tube and hose routing before installation. Inspect the mating fittings, seals, and surrounding cooler lines for wear or contamination, and confirm the connection surfaces are clean before assembly. Match the female-thread and quick-disconnect ends to the original routing on the transmission and lower radiator cooler circuit.
Quality Assurance
Dorman manufactures this replacement transmission cooler hose assembly with metal and rubber components to support leak-resistant fluid delivery in the transmission cooling system. The included gasket or seal helps complete the connection at the installation point.
