Detailed Product Overview
This Dorman transmission line is engineered to move automatic transmission fluid between the transmission and the cooler while maintaining a leak-resistant connection path. It is listed for the outlet (upper) position and connects to the top of the radiator on equipped vehicles. Compatible With 1999-2000 Chevrolet Silverado 2500, outlet (upper), 2000 Chevrolet Suburban 2500, outlet (upper), 1999-2000 GMC Sierra 2500, outlet (upper), and 2000 GMC Yukon XL 2500, outlet (upper). Part number 624-273 is a practical replacement when the original cooler hose shows age-related wear or routing damage. This part cross-references 5801420 and 15717834 for the same application.
Common Problems This Part Can Address
- Transmission fluid seepage at the cooler line
- Cracked, hardened, or deteriorated hose material
- Restricted fluid transfer between the transmission and radiator cooler
- Damaged molded routing on the upper outlet line
- Loss of proper transmission cooling flow on heavy-duty applications
Installation Notes and Tips
Verify the vehicle has RPO code KNP heavy-duty transmission cooling system before ordering. Confirm the outlet (upper) routing and top-of-radiator connection point match the original line. Inspect mating surfaces and adjacent cooler fittings for wear before installation. Because no gasket or seal is included, reuse or replace any required sealing components separately as needed. Part number 624-273 should be matched to the original line length, shape, and connection layout before installation.
Quality Assurance
Dorman manufactures this hose assembly using metal and rubber materials selected for transmission fluid service and temperature exposure in demanding cooling-system applications. The construction supports leak-free fluid delivery between the transmission and transmission oil cooler on the listed Chevrolet and GMC trucks and SUVs.
