What happens when the lock-up clutch is activated in a modern torque converter?

• The torque multiplication ceases

• The turbine and pump turn at the same speed

• The turbine is disconnected from the pump

• The reactor spins faster

Why does the turbine turn slower than the pump in a torque converter during normal operation?

• To increase torque multiplication

• To absorb energy from the fluid

• To center the turbine with the crankshaft

• To reduce energy loss in the fluid

What is the purpose of the one-way clutch connected to the reactor in a torque converter?

• To increase torque multiplication

• To absorb energy from the fluid

• To center the turbine with the crankshaft

• To allow motion in one direction only

How does the torque converter help in multiplying torque as the vehicle starts to move?

• By increasing the engine speed

• By reducing energy loss in the fluid

• By diverting fluid flow for improved swirl

• By locking the turbine with the pump

What is the role of the pump in a torque converter?

• To transfer engine power to the transmission

• To absorb energy from the fluid

• To center the turbine with the crankshaft

• To increase torque multiplication
