456-3657: Torque Converter Impeller

A Torque Converter Impeller is a fan-like wheel with curved blades that is attached to the torque converter housing. It is driven by the engine's crankshaft and rotates at the same speed. The impeller is responsible for circulating transmission fluid through the torque converter, which allows it to transmit torque from the engine to the transmission.

Attributes:
• Smooth out engine power delivery by absorbing shock and vibration
• Increase torque by creating a centrifugal force that propels the transmission fluid
• Hardened to BHN 80 minimum to withstand high loads and stress

Applications:
A Torque Converter Impeller is used to amplify engine torque at low speeds, ensuring smooth starts and preventing engine stalls. By rapidly spinning the transmission fluid, it creates a fluid coupling that multiplies torque before it reaches the transmission gears.
