Exam 6: Automatic Transmission Fundamentals

Technician A says multi-disc clutches and bands are mechanically controlled. Technician B says one-way clutches and sprags are hydraulically controlled. Who is correct?

Which of the following is NOT a function that separates an automatic transmission from a manual transmission?

Technician A says a multi-disc clutch is a holding/application device in an automatic transmission. Technician B says a one-way roller or sprag is a device that typically drives another component in an automatic transmission. Who is correct?

Which of these transmissions uses two, either wet or dry, clutches in place of a standard torque converter to connect the engine to the transmission?

Tech A says that dog clutches are used on most automatic transmissions. Tech B says that all transmissions utilize helical cut gears. Who is correct?

The transmission can automatically couple and uncouple from the engine when needed, much like a clutch on a manual transmission vehicle.

Two technicians are discussing automatic transmission clutches. Technician A says one-way clutches prevents components from turning in either direction. Technician B says that one purpose of a multi-disc clutch is to hold one rotating member to another rotating member. Who is correct?

As the vehicle begins to move from a stop, torque multiplication is minimal because there is a large difference between the speed of the impeller and the turbine.

Tech A says that dual-clutch transmissions are more like a manual transmission internally. Tech B says that the driver needs to operate the clutches on a dual-clutch transmission. Who is correct?

A torque converter does all of the following except:

Technician A says there are two major differences between an automatic and manual transmission. Technician B says that due to the number of vehicles with automatic transmissions installed, it is important for a technician to have knowledge of automatic transmission fundamentals. Who is correct?

Two technicians are discussing automatic transmission clutches. Technician A says one-way clutches prevents components from turning in either direction. Technician B says that one purpose of a multi-disc clutch is to hold one rotating member to another rotating member. Who is correct?

All of the following statements with respect to automatic transmission are true except:

An automatic transmission is generally defined as a transmission that will automatically upshift and downshift in response to engine speed and load.

Which of these transmissions uses two, either wet or dry, clutches in place of a standard torque converter to connect the engine to the transmission?

Which of the following is NOT a function that separates an automatic transmission from a manual transmission?

Today, the majority of vehicles sold in North America are equipped with automatic transmissions as standard equipment.

Which of the following is NOT a holding device used in an automatic transmission?

Tech A states that most automatic transmissions use pneumatic pressure to apply individual clutches and bands. Tech B states that most automatic transmissions use hydraulic pressure to apply individual clutches and bands. Who is correct?

When a gear is selected in an automatic transmission, the input shaft becomes locked to the output shaft of the transmission through which of the following?
