What is a transmission cooler hose?

The transmission oil cooler hose on a car helps to carry the transmission fluid from the transmission to the transmission cooler. The oil cooler is designed to lower the temperature of the transmission fluid to make it easier for the internal parts of the transmission to use.

Where are transmission cooler lines?

Metal transmission cooler lines are typically pre-bent with fittings that are held on by a flare at each end of the line. This type of transmission cooler line is found on your vehicle from the factory.

Is transmission connected to radiator?

Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. Your car’s transmission lines are essential to preventing the transmission from overheating by carrying hot fluid away from the transmission until it is cooled and subsequently pumped back into the transmission.

How do transmission cooler lines connect to radiator?

The hoses traveling from the transmission to the radiator are called transmission cooler lines. 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.

Can you use rubber hose for transmission cooler lines?

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 happens if your transmission gets too hot?

A transmission that frequently overheats can cause fluid to leak from the transmission, so if you are constantly replacing the fluid, it’s a good indication of a leak. A slipping transmission is also an indication of low, dirty, or burnt transmission fluid. You also need to be aware of the check engine light.

Can I use rubber hose for transmission cooler lines?

How long does it take to change transmission cooler lines?

Repairing the cooling line for your transmission can take quite a bit of time. You can expect to leave your vehicle at the repair shop for a day or two for this repair.

How does transmission fluid get cooled?

Automatic transmissions produce a great amount of heat and must be continually cooled. The fluid is cooled inside the radiator in a separate heat exchanger called a cooler tube which is made of brass. The transmission fluid circulates through it, is cooled by the engine coolant and then sent back to the transmission.

Should I bypass my radiator when installing an external transmission cooler?

Should I Bypass My Radiator When Installing An External Transmission Cooler? It is recommended however to keep the factory radiator transmission cooler and use and external cooler if you live in a cooler climate. The factory cooler will help get the transmission temperature into a suitable range.

Can you use compression fittings for transmission lines?

P.S. Compression fittings on trans cooler lines should be fine, but then, adding a bit of hose and clamps would also work well, and be easier.

How much psi should be in a transmission cooler line?

there is at idle between 20-50 psi but during use pressures in transmission lines can reach 100 psi or more. if you are going to use rubber lines be sure to use barbed fittings so the hose does not blow off. Cooler and lube pressure are about the same at 5-30 psi.

What are transmission hoses going into the radiator called?

What are transmission cooler lines in a radiator?

How do you get transmission fluid out of radiator?

Raise the vehicle with a jack and set it on jack stands. Locate the transmission cooler line fitting at the back of the radiator and remove it by turning it counterclockwise. Have a rag ready as transmission fluid will seep out.
