The torque converter is a fluid coupling that transfers power from the engine to the transmission. It consists of three main components: the impeller, the turbine, and the stator. The impeller is connected to the engine and the turbine is connected to the transmission. The stator is located between the impeller and the turbine.
When the engine is running, the impeller rotates and the fluid inside the torque converter begins to move. The fluid then strikes the turbine blades and causes the turbine to rotate. The stator helps to direct the fluid and increase the torque output of the torque converter.
If any of the components of the torque converter break, it can cause a rattling sound. Some of the most common parts that can break are the impeller blades, the turbine blades, and the stator vanes. When these parts break, they can cause the torque converter to vibrate and produce a rattling sound.
If you hear a rattling sound coming from your car, it is important to have it inspected by a mechanic as soon as possible. A broken torque converter can cause serious damage to your car's transmission.
