How Long Does A Torque Converter Last


A torque converter is an automatic transmission device that shifts into action when you start moving your vehicle forward. It comes in two varieties, first-stage or dry and second- stage or wet. As you know, once the engine gets going it keeps powering along no matter what angle the car is at!

The torque converter was invented back in 1937 to help deal with one problem; how do you get a heavy vehicle like a truck up to speed? The answer is for someone else to do the work of getting it started! By using a torque converters first stage, they can take care of shifting the fluid quickly so that you don’t have to. This cuts down drag and helps give you better fuel economy.

There are also second stage ones which are designed to handle more power by taking longer to shift. These are not good if you need instant acceleration as there will be too much delay while the engine spins up.

History of torque converters

The first use of a torque converter was in 1884 by Karl Benz, an engineer at Daimler AG. He built it to help facilitate easier starting of his company’s motorized vehicles.

Torque is the product of force times distance traversed. For example, if I push my car forward with 100 pounds of pressure and go one foot down, then the engine receives 100 new horsepower because it has to work against that weight for one second before it gets going!

The clutch inside most cars disengages the torque converter from the engine when you take your hand off the gas pedal. This cuts off the power immediately without wasting any energy keeping the two connected.

Most people are familiar with how a torque converter works when they start their vehicle due to the noise and vibration they hear and feel as the device connects up with the engine. However, less known is what happens next. You may have noticed a small drop in sound as the converter breaks away- that’s the air rushing out! It takes some time for the fluid in the torque converter to stop spinning, so there’s a brief period where there’s no obvious change in tone or speed.

That’s why many consider the converter to be mostly silent until it drops out- only hearing it in action when it finally gives way.

How torque converters work

A fluid-to-solid transition is occurring in your car when you turn the engine on! That’s how torque converters work, which are used in automatic transmissions to seamlessly transfer power from the engine to the wheels as needed.

You probably already know that torque comes from spinning components like a motor or an axle, and it gets transferred through a shaft. The converter adds another rotating component between the engine and the transmission, making the vehicle more efficient at pulling momentum off the back end and transferring it to the front end.

The longer the converter stays open while the engine turns over, the higher the efficiency of the system. But if it isn’t closed long enough for the oil to drain out, then it can cause damage to the internal parts.

We’ll talk about why that happens in just a minute, but first let’s take a look at how torque converters work. We will also discuss some common misconceptions about them.

How to check torque converter health

The automatic transmission fluid is one of the most important parts of your car. Without it, you would not be able to start your vehicle!

That is why it is so crucial to make sure that you are never low on transmission fluid- you could potentially lose all power if that happens!

There are several ways to check for engine fluid loss. If you feel there is some drop off in performance, then it is time to change the fluid!

You can also check the thickness of the fluid by using a thin piece of paper or cardboard.

The life of the torque converter

Aftermarket performance gear often includes replacing components such as the clutch, dry sump oil system, or engine bay covers. These are usually replaced due to corrosion or wear and tear. However, what people may not know is that most of these parts have an average lifespan!

Clutches, oil systems, and other internal combustion equipment use a fluid called hydraulic fluid to function properly. As the machine uses energy to turn the wheels, there must be resistance to this turning motion in order for it to work. A torque converter functions by using this fluid to do so!

By having fluid move quickly from one place to another, the torque converter can transmit power effectively. Because they play such an integral part in powering your car, aftermarket converters typically last longer than OEM ones!

However, like any mechanical device, over time their efficiency will begin to drop.

Water damage and torque converters

The engine in your car is strong, but it doesn’t last forever. That engine life span can be shortened by water exposure or fluid leaks that cause corrosion.

Corrosion is when atoms from another element are attached to the surface of an object. In this case, oxygen gets attached to the surface of the vehicle part and breaks down the original material, creating a weaker layer.

Water can sometimes get into your car through cracks, holes, or spills. These things may allow water to reach the parts of your car that have metal in them, such as brake lines, fuel pipes, or intake hoses.

If you find liquid inside your car, check out if it’s dry for at least a minute! If it has dried, then try to remove it and see what kind of fluid it is. You don’t want to touch it with your hands because some fluids can hurt or even burn you.

Hopefully you will never need to replace your own torque converter, but it is good to know how long they usually last so you aren’t too surprised if you do.

Bad engine oil and torque converters

One of the biggest reasons that your car will fail is due to poor engine oil. Engine oils are integral to ensuring your vehicle runs smoothly and reliably.

Engine oils help prevent friction in various parts of the engine, which helps power production and fuel efficiency. If engines were perfect without engine oil, then there would be no need for engine overhauls or synthetic oils!

As cars become more powerful and efficient, they require better quality oil to run properly. Unfortunately, most popular brands are not designed for high-performance use – instead, they are engineered for mileage and reliability.

If you are looking to upgrade your engine’torque converter, make sure to get top notch engine oil before installation.

Bad transmission oil and torque converters

Changing your car’s engine oil is one of the most important maintenance procedures you can do to keep it working properly. Engine oils are designed to be replaced regularly, however, some oils have a shorter lifespan than others.

A torque converter clutch (TCC) in your vehicle requires special gear lube that will break down over time. If you are looking to sell your vehicle or want to make sure it lasts as long as possible, then it is important to know how much life the TCC gear lube has left.

This article will tell you just that! Read on for all the information you need.

Dirty torque converter fluid and torque converters

Having poor torque converter fluid is very common when buying or selling a vehicle. A lot of sellers drop dry mineral oil in their engine’s hydraulic system to help them start their car every day, but they forget to check if it goes into the transmission as well!

This can cause premature failure of the transfer case, which is what controls momentum carried from one gear to another. This also puts extra stress on the gears, causing damage and eventual failure.
