The torque converter is a fluid coupling that transfers rotational power to the engine in automatic transmission vehicles. However, many people do not know how the converter works and its advantages and disadvantages. Hence, understanding its operation and care can help you maintain your vehicle’s health.
We’ll explain what is a torque converter and its importance to ensure your car’s transmission system works properly.
How a Torque Converter Works
The vehicle’s automatic transmission system features a torque converter for changing gears. The torque converter is responsible for transmitting the power from the engine to the gearbox. This is done through a hydraulic system.
With the help of a hydraulic system, the torque converter allows the car to stop and move. The converter also transfers power from the engine to the transmission, reducing the bumps while driving.
Another function of the torque converter is that it allows several rotations between the car transmission and the engine.
Torque Converter Parts
In addition to the fluid, the torque converter has three parts:
Turbine
Connected to the transmission shaft, the turbine is responsible for multiplying the torque of your engine. When the vehicle is stationary, it needs more force to move. The turbine precisely helps to transfer power from the engine to the transmission system.
Pump Booster
Fixed on the torque converter housing and connected to the engine, the pump impeller has the function of rotating the transmission fluid and sending it to the turbine. It transfers the power from the engine to the transmission system.
Stator
As the name implies, this part is located between the turbine and the pump impeller. It stabilises the fluid that arrives at the turbine, sending it back to the impeller. This fluid rotation causes a multiplication of the torque, helping the engine’s power, especially when the car is operational.
Advantages and Disadvantages of Torque Converter
Some of the advantages and disadvantages of the torque converter are mentioned below:
Advantages of Torque Converter
The torque converter has several advantages some of them include:
- Less noise
- Less wear on transmission components
- Smooth clutch engagement
- Does not need human action for the system to operate
Disadvantages of Torque Converter
The main disadvantages are:
- Higher fuel consumption, especially when it does not have a blocking system
- Expensive maintenance
- More fluid change needed
- Depending on the engine rotation speed
Symptoms of a Bad Torque Converter
You will see observe the following symptoms when the torque transmission is faltering:
Converter Overheating
This usually happens because the transmission fluid is low. As a result, the part will not be able to do the job properly. Also, low fluid can malfunction the torque converter. Hence, if the converter overheats, it will not be able to transfer power to the transmission motor. As a result, you will have poor acceleration and system wear.
Also, there are several other reasons for cars overheating. Hence, check if the torque converter is working fine.
Transmission Failures
It could be a problem with the torque converter. This is because engine torque does not convert into hydraulic pressure; the transmission needs to shift gears.
Strange Sounds
Strange squealing sounds are a big problem. They can be identified through clicks or squeaks. However, whatever the case, you will have to pay attention to the noises and take the car to a professional who specialises in transmission.
Faults at Neutral
The malfunction of the torque converter causes failures when engaging the neutral gear. However, there is a way to test the problem, but only a professional will be able to do this test.
With this, we conclude our guide on the torque converter. If you are still driving a manual car, browse through these used cars for sale in the UAE and upgrade your vehicle with better torque. However, before you plan to buy a car with a torque converter, make sure you know the difference between torque converter vs. CVT vs. dual-clutch.
