Technician A says the impeller is driven by the force of the fluid from the turbine and is splined to the input shaft. Technician B says the torque converter's impeller is driven by the converter cover, and its rear hub drives the transmission's or transaxle's oil pump. Who is correct?

Quizplus · Accepted Answer

Technician B is correct because the impeller, which is part of the torque converter, is indeed driven by the engine via the converter cover (also known as the torque converter housing), and its rear hub is typically connected to the transmission's or transaxle's oil pump, providing the hydraulic pressure needed for the transmission to operate. Technician A's statement is incorrect because the impeller is not driven by the fluid from the turbine; instead, it drives the fluid towards the turbine.
