When you operate your automatic transmission vehicle, you have complete control over the torque converter. That’s because torque converters transform the power generated by your car’s engine into electrical energy that is then fed to your car’s gearbox. You’ve instructed your torque converter each time your vehicle switched gears, therefore it’s no surprise that you’d want to command it once more before going beneath a bridge. As a result of this, there is a global market for torque converters.

The worldwide torque converter market is anticipated to expand at a CAGR of 4.54% through 2021, according to Transparency Market Research. This is owing in part to technological advancements in torque converters. Torque converter faults have a significant impact on your automobile’s ability to perform and drive.

In this post, we’ll discuss the torque converter component of an automatic transmission. You will learn how a torque converter works, what signs indicate that it is faulty, and what the typical cost of replacing one is after reading this material.

What is A Torque Converter and How Does it Work?

The torque converter in between the engine and transmission is what transmits rotational power from the engine to the gearbox. This device, which fits between the transmission and engine, transforms torque by turning the flexplate with a crankshaft.

A pump with a number of blades is hidden beneath the torque converter cover. These blades spin in unison with the engine crankshaft, similar to those on a propeller. This causes fluid from the transmission to flow onto the impeller’s blades.

The output shaft of the transmission is connected to this component. The speed and gear of the automobile are determined by how much hydraulic pressure is produced within the transmission in this manner.

How Can We Tell When A Torque Converter becomes Faulty?

The torque converter may break down for a variety of reasons, including incorrect maintenance, overtightening, lack of lubrication, coolant leaks, and so on. Because of this, many drivers believe their transmission is failing when in fact it’s the result of one or more issues with the torque converter.

They may not know that it’s possible that the torque converter is faulty instead. The cost of replacing the torque converter is far less than that of a transmission replacement.

When the torque converter wears out, the vehicle’s power must be increased in order to maintain the same speeds. The engine cycle will need more revolutions per minute to complete, reducing transmission fluid pressure and fuel efficiency.

The system, on the other hand, generates far more heat, which can lead to additional difficulties in a variety of situations.

Torque Converter Rebuilders: How Long Does it Last?

A transmission rebuild involves a number of components that must work in perfect coordination. There are more than 1,000 distinct parts, ranging from tiny springs to massive heavy gears. New soft components such as seals and clutch discs are added to existing ‘hard parts’ like gears and pumps during a transmission rebuild.

A rebuilt transmission is projected to survive between 30,000 and 50,000 miles on average. A rebuild can last as long as the original transmission, which is around 120,000 to 200,000 miles on average if done correctly and regularly maintained.

There are several elements that influence rebuilt transmission dependability, including the quality of the rebuild, the condition of the transmission being rebuilt, and the maintenance method.

Benefits of Torque Converter Rebuilders

A remanufactured transmission, on the other hand, is a fantastic option if you don’t want to buy a brand-new one. These are completely re-engineered and put together in a factory production line. Many of these designs, when compared to their stock forms, include a lot of upgrades, which means many of the design errors that cause components to fail prematurely may be avoided. This might extend the service life of a reman transmission considerably beyond what it would have had if it were used in its stock form.

The inspection team for torque converter rebuilders checks all of the critical components in the donor transmission, from end to end, to ensure that they comply with the manufacturer’s standards and tolerances. Inspect the case, gears, pumps, shafts, torque converter for hairline fractures, valve body, metal tensile strength, warping, and other characteristics. If a component doesn’t fulfill the required standards it is discarded and replaced.

The components are then washed and sent to the appropriate stations on the assembly line for reassembly. Quality control managers examine the build throughout the procedure to ensure that it fulfills the promised criteria. The final step of the process is to modify the engine, including any necessary upgrades or changes, to address factory design flaws. The valve body is rebuilt and tested on a special dyno machine to guarantee that it meets the requirements. Prior to installation, all of the solenoids are checked.

The software program C.A.R.S. (Computer Aided Real-world Simulation) is used to test the remanufactured transmission on a specialized dyno machine in the dyno room after it has been built and passes its final quality control inspection. The transmission is subjected to a variety of real-world driving conditions in order to assure that it meets the manufacturer’s requirements. It also aids in the break-in of all of the friction components, ensuring that it is fully adjusted and ready to use when installed.


If you or someone you know has any of the symptoms listed above, your torque converter is most likely to be at fault. The cost of repairing your torque converter will in all likelihood exceed the price of replacing it. But, rather than making any hasty judgments, have a specialist or automobile expert examine it first.

The average cost for a torque converter replacement ranges from $600 to $1,000, according to the National Automobile Dealers Association. If you want to perform the replacement task yourself, a new torque converter will set you back anything from $150 to $500.

The precise cost varies based on the manufacturer and model of your car. If you do it yourself, at the very least you’ll be eliminating labor expenses.
