Question

​Technician A says when the transmission is in gear, the fluid coupling allows the vehicle to stop without stalling. Technician B says this is because the impeller doesn't rotate fast enough to drive the turbine. Who is correct?
A)​A only
B)​B only
C)​Both A and B
D)​Neither A nor B

Quizplus · Accepted Answer

Both technicians are correct. Technician A is correct in stating that the fluid coupling allows the vehicle to stop without stalling because it can slip when necessary, such as when the vehicle is stopped while in gear. Technician B is correct in explaining that this is due to the impeller not rotating fast enough to drive the turbine, which allows for the necessary slippage to prevent the engine from stalling.
