The rear half of the torque converter shell is shaped like a hollowed-out donut and is called a _______.

• A. Pump drive hub
• B. Torus
• C. Vortex
• D. Stator

Answer: (B)

This question tests recognizing a geometric term for a component shape. The rear half of the torque converter shell forms a hollow ring around the center, like a donut. That doughnut shape in geometry is called a torus. The torus provides the outer housing while leaving an inner cavity for the turbine and the stator to operate inside. The other terms refer to different parts or concepts: a pump drive hub is the input-side connection, the stator is a separate internal component, and vortex isn’t a term used for this part. So the donut-shaped rear shell is a torus.
