When the turbine speed is less than about 90% of the impeller speed, the shape of the converter case makes the fluid flow in a circular motion, through the impeller, turbine, and stator. What does this create?
A) Overdrive
B) Torque Converter Clutch lockup
C) Torque multiplication
D) Speed multiplication

Question
