In torque converter operation,when does the stator start to freewheel?
A) during torque multiplication phase
B) at the beginning of coupling phase
C) at the end of turbine lock-up phase
D) at the beginning of impeller stall

Question

Quizplus · Accepted Answer

The stator starts to freewheel at the beginning of the coupling phase, as its role in torque multiplication is no longer needed, allowing the impeller and turbine to rotate at nearly the same speed.
