What is a Torque Converter?

A torque converter is a fluid coupling device that is placed between the engine and the transmission in an automatic transmission vehicle. Its primary function is to transfer power from the engine to the transmission to enable the vehicle to move. It uses hydraulic pressure to transfer the power generated by the engine to the transmission. A torque converter consists of four main components; the impeller, turbine, stator, and lock-up clutch.

Working Mechanism

The torque converter is a complex device, and its working mechanism can be quite technical. However, we will try to explain it in simple terms. When the engine is running, it generates power that is transferred to the impeller, which is connected to the engine crankshaft. The impeller, in turn, transmits the power to the fluid that is circulating within the torque converter.

The fluid that is circulating is responsible for the rotational movement of the impeller. The rotating impeller causes the fluid to spin, which is then directed towards the turbine. The turbine is connected to the transmission and is responsible for delivering power to the wheels.

When the fluid reaches the turbine, it causes the turbine to rotate, which then transmits power to the transmission. The rotating turbine generates power that is transmitted to the wheels via the drivetrain. The torque converter allows the engine to rotate at a speed independent from that of the transmission. When the car is at a stop, the torque converter allows the engine to idle without stalling.

Lock-up Clutch

A lock-up clutch is an essential component of a torque converter. It helps to reduce energy losses in the torque converter. The lock-up clutch is used to mechanically connect the impeller and turbine, allowing them to rotate at the same speed. This helps to reduce the amount of slippage that occurs in the torque converter, reducing energy losses and increasing efficiency.


The stator is another essential component of the torque converter. It is located between the turbine and impeller and is responsible for redirecting the fluid back to the impeller. The redirected fluid helps to increase the torque coming from the impeller before it reaches the turbine. This increases the efficiency of the torque converter, allowing for more power to be transmitted to the wheels.
