Which component in a torque converter is described as being splined to the input shaft and positioned very close to the impeller without touching it?

• A. Impeller
• B. Turbine
• C. Stator
• D. Pump drive hub

Answer: (B)

In a torque converter, energy is transmitted from the engine to the transmission through hydraulic fluid. The impeller is driven by the engine and pushes fluid toward the turbine. The turbine is splined to the transmission input shaft, allowing it to rotate with that shaft, and it sits very close to the impeller without touching. The tiny gap and the fluid in between let torque flow from the engine to the transmission smoothly and enable torque multiplication, especially at lower speeds. The stator sits between the two and redirects fluid to improve efficiency, while remaining mounted to the converter housing rather than the input shaft.
