What is the purpose of the stator in a torque converter?

• Controls the vehicle's speed

• Causes the fluid to change direction and multiply torque

• Filters the engine oil

• Regulates the tire pressure

When does the torque converter clutch engage?

• At cruising speed after shifting through all gears

• When the vehicle is in reverse gear

• During acceleration from a stop

• When the engine is turned off

What is the significance of stall speed in a torque converter?

• It measures the tire pressure

• It is the point where torque multiplication occurs during acceleration

• It indicates the maximum engine speed

• It controls the vehicle's braking system

Which component of the torque converter is responsible for locking up the turbine and impeller?

• Torque converter clutch

• Stator

• Turbine

• Impeller

What happens when the torque converter clutch fails to disengage?

• It activates the cruise control system

• It improves the vehicle's acceleration

• It increases the fuel efficiency of the vehicle

• It can cause the engine to stall when coming to a stop

How does the stator contribute to torque multiplication in a torque converter?

• By increasing the engine RPM

• By changing the direction of the fluid flow

• By reducing the engine temperature

• By adjusting the suspension system

What is the function of the impeller in a torque converter?

• Regulates the brake system

• Controls the vehicle's audio system

• Spins with the engine to move fluid through the converter

• Monitors the tire pressure

When does the torque converter clutch lock up in a vehicle?

• At cruising speed after shifting through all gears
