Which statement correctly describes the physical relationship between the turbine and impeller in a torque converter?

• A. Technician A
• B. Technician B
• C. Both Technician A and Technician B
• D. Neither Technician A nor Technician B

Answer: (B)

The main idea is that the turbine and impeller are connected only through hydraulic fluid, not by a direct mechanical linkage. In a torque converter, the impeller is attached to the engine and spins with it, while the turbine is attached to the transmission input shaft. The space between them is filled with transmission fluid, and as the impeller pushes fluid outward, that fluid flows to the turbine and makes it rotate. Because the fluid medium transmits power without a solid connection, the turbine can rotate at a different speed than the impeller, producing slip and allowing torque to be multiplied at low speeds. The stator sits between them to redirect the flow and improve torque transfer. So the correct description is that there is hydraulic coupling between the two, with no direct mechanical connection.
