How Torque Converter Automatic Transmission Works

The convenient feeling of driving an automatic vehicle becomes enjoyable because one does not have to care over the gear changes and this automatic work is done by a torque converter. A manual car does not have a clutch, it possesses a torque converter that stops the spinning of the engine from the transmission when brakes are applied.

The torque converter is a fluid that combines the engine and the transmission and has several important functions. This fluid is thrown with a pump using centrifugal force caused by it. It contributes to smooth gear changing.

Clark Torque Converters

Clark is a well-established name in the industry known for providing reliable and efficient pieces of whatever they provide, especially torque converters. Clark converter are considered the best pieces in the market because of their high quality.

Clark converter is very advantageous. Besides the pros of being a high-quality piece, it has the following features:

  • They extend a vehicle’s life by absorbing shock
  • They allow power shift transmission
  • There are no complications and require no adjustments on a periodic basis

Components of a Torque Converter

It has four components namely pump, stator, turbine, and transmission fluid.

  • Pump

The pump is a component in the torque converter that allows it to move the liquid outside.

  • Turbine

The liquid from the pump is transferred to the turbine.

  • Stator

It ensures the right direction of the fluid after moving out of the turbine towards the pump. It boosts the efficiency of the converter. By redirecting the fluid, it gathers all the energy and delivers it back to the engine.

  • Transmission liquid

With the transmission liquid, the power from the engine is delivered to the transmission.

How does Automatic Transmission occur?

The torque converter seizes the rotation of the engine from the transmission when brakes are applied. These two systems transmitting energy are hydrostatic and hydrodynamic.

The pump being directly in contact with the engine turns at a similar speed as the engine. The liquid carried in the pump thus gets flung out due to the centrifugal force caused by the rotation of the pump and thus pressure increases. The turbine is connected to the transmission. It bangs with the blade of the turbine and due to this force of swirling liquid and pressure so caused, the turbine rotates.

The combining of the fluid is done and the transmission of engine power is completed by the flow of the liquid. A component called a reactor or a stator has to be fitted between the pump and turbine.

Clark converters have the capacity to multiply the torque. Factors affecting its multiplication include speeds of pump and turbine, number of blades in these components, and angles of these blades.


To sum up, torque converters have high power transmission capacity and accelerate better along with the capacity to multiply torques like the Clark converter. These are better able to adjust the gear ratio and are best suitable for the enhanced driving experience because the speed can be adjusted accordingly.
