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.
Why do transmission lines go to the coolant radiator?
These lines pull transmission fluid from the transmission and take it to the radiator, where it cools down. They then circulate it back to the transmission where it keeps doing its job. Like all parts of an engine, transmission cooling lines can wear out.
How much does it cost to have transmission cooler lines replaced?
The average cost for trans oil cooler line replacement is between $242 and $270. Labor costs are estimated between $108 and $137 while parts are priced at $133. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location. Related repairs may also be needed.

How long does it take to change transmission lines?
The timing will also vary depending on your vehicle model, year, and damage condition. On average, installing a new transmission cooler line on any auto vehicle takes a minimum of 1 & 1/2 hours to a maximum of 2 hours.

How do I know if my transmission cooler is leaking?
One of the more obvious signs of a failing transmission cooler is a leaking transmission cooler line. If you see pinkish or reddish-brown liquid under the front of your car or under the transmission, you likely have a leaking line on your hands.
What happens when transmission cooler fails?
When a transmission oil cooler hose fails it can cause the transmission to overheat. This can be due to low fluid level from a leak or preventing flow. In either case if the transmission overheats it can stop working entirely and this condition may be permanent.
What runs through transmission cooler lines?
Fluid heated by the transmission, engine, or power steering pump flows to the cooler. The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line.
Over time, road debris and heat can cause the transmission fluid lines to crack or break, which can cause fluid to leak out. Another reason for lost fluid is your vehicle’s torque pump has become cracked or an axle seal has been compromised.
Can you drive with a broken transmission line?
In most cases, it’s probably not dangerous to drive your car if it’s leaking transmission fluid. But, running your car with little to no transmission fluid can cause damage to your whole engine.
What transmission line goes to the radiator?
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 you drive with a leaking transmission cooler line?
Sometimes, it is difficult to spot the leak at the initial stage. With that, the question comes whether you can drive around with leaking cooling lines. Well, you can but should not. The faulty lines can discharge a great amount of fluid pretty quickly, resulting in possible transmission failure.
How serious is a transmission line leak?
A transmission leak will not get better on its own. If it goes unchecked, vehicle operation will eventually be affected, and you may find yourself with an expensive repair. So, while it may be safe to drive with a leaking transmission, it’s not advisable, and you shouldn’t put off fixing the problem.
The cooler pressure is not published anywhere that I can find but most automatic transmission’s have about 4 to 10 PSI. You have to keep in mind the cooler pressure is low because the oil is flowing to lubricate the gears and there is not much resistance in the lines.
Can a transmission leak cause a fire?
Yes, transmission fluid can start a fire. The most likely scenario for it to cause a fire is when it leaks from the transmission onto your engine. (Though it is unlikely that it will catch fire when you’re topping up the fluid in your vehicle.)
What temperature does transmission fluid catch fire?
Automatic transmission fluid has a flashpoint in the 300-383-degrees Fahrenheit range, meaning it can auto-ignite at this temperature. A thing to note is that the automatic transmission fluid flash point is lower than its boiling point, and despite being a high value, it is safe to consider it as a flammable substance.
What temp does transmission fluid boil?
Fluid Life Expectancy vs Temperature
The ideal operating temperature of transmission fluid is 175 degrees. Overheating occurs after the temperature surpasses 200 degrees, and the failure rate doubles for every additional 20 degree increase after that.
What happens if you spilled transmission fluid on engine?
It shouldn’t cause any amount of damage to your engine. Many old time mechanics used to (and maybe they still do) put tranny fluid into the engine to clean it out prior to an oil change.
How long can a car run without transmission fluid?
How long can a car run without transmission fluid is up to about 10 miles on low to no transmission fluid, but doing so would be extremely risky. Transmission fluid is essential for helping your car shift gears smoothly. Without it, gears are exposed to added friction and may not be able to move at all.
