• True

• False

When a higher gear is engaged (higher vehicle speed) :

• Overdrive

• Underdrive

• The 5th wheel

• Opendrive

A clutch disc:

• Provides method of power transfer between the flex plate and input shaft.

• acts as a brake for the transmission.

• Provides method of power transfer between the flywheel and input shaft

• is very durable and resistant to damage from insufficient force from the pressure plate.

The clutch system component that applies/releases frictional force to/from the clutch disc is

• clutch release bearing

• the flywheel

• a pressure plate

• clutch fork

• True

• False

A planetary gear set consist of a Sun gear, planetary gears and a __________________.
