What are transmission cooling lines made of?
Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.
Can you replace transmission lines with rubber hose?
You can use rubber hose, but make sure it’s transmission cooler line rated. The pressure is quite low (12-15 psi). Double clamp it or use FI type clamps instead of the worm-drive style.
What kind of hose do you need for automatic transmission?
These can be cut and secured with standard hose clamps. Your automatic transmission is also a hydraulic system, and the fluid has to be cooled. This is done through hard lines that connect to the radiator. There is a rubber line that serves as a flex joint, this must be hydraulic hose.
How does a transmission hose go into the radiator?
They channel hot transmission fluid to the radiator, where it is cooled, then return it back to the transmission. They typically resemble brake lines and are made of metal. Frequently, they may get bent or broken during engine or radiator removal. Older vehicles often have these lines patched with rubber fuel lines.
What kind of hose to use for transmission cooler lines?
DIYers may be tempted to use any hose available in the garage but only new high-quality hoses made with chlorinated polyethylene (CPE) with a Hypalon cover (Hypalon is a synthetic rubber material resistant to chemicals, temperature extremes, and ultraviolet light) should be used.
Why are transmission cooler lines made of nylon?
Nylon braided transmission cooler lines, like their name indicates, are rubber lines encased in a protective nylon cover. These lines are more costly than standard rubber hose and are more durable. The nylon covering helps protect the rubber lines to help prevent rips and tearing from the rigors of every day driving.
