Can I 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.

Yes it HAS to be designed for hydraulic fluid. Trans fluid & regular rubber fuel line aren’t compatible, as it will swell it & leak. If I have to use any hose on the transmission line, I usually flare the steel line before I slip on the rubber hose, it helps to keep the hose from blowing off.

Also Know, can you use copper tubing for transmission cooling lines? Are there any issues using the copper nickel tubing for transmission cooler lines? It’s much easier to work with than steel lines, and not all that expensive either. And since they are used for brake lines, they should hold up to the transmission line pressures rather easily (or so I would think.)

Secondly, can fuel hose be used for transmission cooling lines?

Yes, you can install cheap fuel hose, and it WILL work but the question is, ‘for how long?’ . Transmission cooler hose is noticeably thicker and stiffer, and you can safely assume that the type of rubber used will work long-term with atf.

How much pressure is on a transmission cooling 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.

How much does it cost to replace a transmission cooling line?

Once those lines start to malfunction, then the transmission fluid can overheat. You will pay somewhere between $100 and $450 for a transmission cooler line replacement. The labor should be between $60 and $300, while parts can cost you anywhere from $40-$160.

What size are transmission cooler lines?

Transmission Cooler Fittings and Placement Information Fitting Location Thread Size Flow Direction Upper 1/8” Pipe Return/in Lower 1/8” Pipe Cooler feed/out

What causes low line pressure in a transmission?

Either of these require that the oil pan, valve body, or transmission be removed for inspection and repair. Line pressure is normally effected by throttle position and the gear range. Pressure that are lower than specifications are usually caused by leaking seals or a worn oil pump.

Are fuel lines Oil resistant?

Fuel line is a petroleum-resistant nitrile tube with a covering that resists weathering, ozone and heat and can be used for ethanol-laced fuels and diesel fuel. It should, however, not be used on coolant systems, oil systems or fuel-injection systems that produce pressures higher than 50 psi.

Can you use coolant hose for oil?

Heater hose line is designed for coolant and as such does not get along well with oil. Over time the hose will expand and also harden and become brittle.

Can you use fuel hose power steering?

You can NOT use fuel hose for ATF/steering. You can’t even use it for fuel injection. Fuel hose is for gravity, vacuum, or extremely low pressure fed fuel systems, not to be confused with fuel-injection hose. ATF/PSF are hydraulic pressure lines.

What are transmission cooler 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 metal fuel line with rubber?

The absolute best way is to replace the entire steel line. When this isn’t possible, use as much steel as you can and as little fuel injection rated hose as possible. The issue with rubber hose is that it will seep fuel if the outside of the steel line is rusty or has a rough uneven surface.
