The torque converter is an intermediate car component that is located between the engine and the transmission. It converts the raw torque produced by the engine into power that the transmission can transmit to the wheels. There are four parts to the torque converter:
The impeller is the input device that receives the raw torque from the engine. It is attached directly to the engine’s flywheel which allows the impeller to turn as the engine runs. As the impeller turns, its blades direct transmission fluid through the rest of the torque converter.
The turbine is the output device that sends the converted engine power to the transmission. It is attached to the transmission input shaft.
The stator is located at the center of the torque converter. Its angled blades direct transmission fluid toward the turbine to be used by the transmission itself. Doing this multiplies the power that the transmission receives.
In some cars, a converter clutch links the engine and the transmission directly to help prevent gear slippage. This also helps keep the transmission healthy and increases fuel economy.
Signs of a bad torque converter
- Check engine light illuminates
- Car shudders at cruising speed
- Poor acceleration
- Whirring noise
- Transmission fluid leak
- Transmission slippage
Torque converter maintenance
If you notice any of the above signs, get your car serviced by a car care professional right away. Sometimes the transmission will produce a diagnostic trouble code that will indicate an issue with the torque converter. Issues with the torque converter may have been caused by it overheating or the stator spinning improperly or not at all.
