An automatic transmission cooling line or hose is a transmission system component designed to circulate transmission fluid between the gearbox and the cooling radiator or heat exchanger. It removes excess heat from the ATF and maintains proper transmission operating temperature.
Cooling lines connect the transmission to the radiator or integrated heat exchanger and work together with the transmission pump, cooling circuit, and engine system. They may be made as rigid metal pipes, reinforced rubber hoses, or combined assemblies.
A damaged transmission cooling line may cause ATF leaks, overheating of the gearbox, harsh shifting, pressure loss, oil contamination in the engine bay, or limp-mode activation.
Our catalog includes transmission cooling lines and hoses for many vehicle brands. Available options include genuine factory transmission components, reliable aftermarket replacements, and tested used lines without leaks or deformation. Feed and return lines, versions for different gearbox types, and assemblies with integrated brackets are available.
Used parts are inspected for sealing condition, connector integrity, absence of corrosion, cracks, and structural damage.
Selection is available by VIN number, transmission type, part number, cooling system configuration, and vehicle year. Replacing a faulty cooling line restores proper fluid circulation and protects the transmission from overheating.
