Question: How To Repair A Transmission Cooler Line

Can a transmission line be repaired?

Like all parts of an engine, transmission cooling lines can wear out. If they break or develop a leak, you will lose transmission fluid, leaving your car vulnerable. Thankfully this is a fairly simple fix, and most transmission line repairs cost between $100 and $500 dollars.

Can you use rubber hose transmission line?

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 causes transmission cooler lines leak?

Transmission cooling lines leaking means either low-level of fluid or interrupted flow in the transmission. In both cases, the result is an overheated transmission that may stop functioning if the condition persists. Sometimes, it is difficult to spot the leak at the initial stage.

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

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 fluid runs through transmission cooler lines?

How Car Transmission Lines Work. Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. 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.

Are transmission cooler lines high pressure?

Its NOT only pressure you have to worry about, its also compatibility with the trans fluid. NOT aware of the pressures being any higher than other transmissions, so if you use “Transmission Cooler Hose” you should be fine.

How do transmission cooler lines connect to radiator?

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.

What do oil cooler lines do?

The oil cooler is usually mounted near the radiator and will help to cool the oil with the air that is passing through the engine. The oil cooler lines of most vehicles are made from metal and have compression fittings on either end. Over time, these fittings may start to become worn.

How do I know if my transmission cooler is leaking?

Symptoms That You Need To Know For Transmission Cooling Lines Leaking Reddish Pool Of Fluid Underneath Your Car. Low Transmission Fluid Level. Burning Smell Or Overheating Gearbox. Visible Damage On The Cooling Lines. Odd Noises While Shifting Gears. Difficulty Shifting Into Gear.

How serious is a transmission line leak?

A transmission leak spells serious trouble for your car, truck, or SUV. If you have a leak, low fluid levels can affect the transmission’s performance and damage crucial parts. Transmission fluid is usually red to dark red; it’s pink if there’s a real problem.

Does it matter which transmission cooler line goes where?

Generally the higher line on the radiator has fluid going INTO the transmission and the lower one goes back to the transmission, so the higher line has fluid coming out of it and the lower line sucks it back into the transmission.

Can I use fuel hose for transmission cooler?

Registered. Fuel line hose isn’t up to the pressures normally associated with automatic transmissions. Use the proper stuff. If that thing splits or blows loose and hoses down any portion of your exhaust system hot enough to ignite it, your truck could end up burned to the ground.

Can you use copper for transmission lines?

As copper has very good electrical characteristics. It has a high conductivity. So it is good material for transmission line but the cost of copper is very high as well as high specific gravity because of that it is not used for transmission lines.

How long does it take to repair a transmission line?

Transmission repair can take a full day but it will take at least 3 to 4 days to rebuild a transmission.

What happens when transmission lines leak?

While it is not especially dangerous to continue driving with a leaking transmission fluid, it can cause catastrophic damage to your engine. As soon as you notice your car is leaking transmission fluid, you should seek to contact a certified mechanic to have your transmission fluid serviced.

Do you have to bleed transmission lines?

Do i need to bleed the cooler once installed or will the air just get flushed out? You would not need to bleed the transmission cooler part # D13503 before you install it on your truck. The fluid is thick enough and the pressure it high enough that air bubbles would immediately work themselves out.

What happens if you put transmission cooler lines backwards?

If you had it reversed, the pump would be trying topush fluid through the bottom of the cooler, up through the cooler, out the top into the bottom of the rad, and up through the rad to the top. More weight to push.

How much pressure is there in a transmission line?

During normal operation, its about 150 and the return line around 50 psi.

What is normal transmission line pressure?

Place the transmission in forward position and operate the transmission to 600 RPM. The pressure should read 40 to 70 psi.
