Question 1

In a variable displacement vane pump, what part below changes pump output based on the oil pressure acting on it?

Accepted Answer

The moveable housing of the pump in a variable displacement vane pump adjusts its position based on oil pressure, thereby changing the pump's output.

Question 2

Technician A says the majority of automatic transmission control valves are located inside the valve body. Technician B says a typical valve body is made of aluminum or cast iron. Who is correct?

Accepted Answer

Technician A is correct because most automatic transmission control valves are indeed located inside the valve body. Technician B is also correct because valve bodies are typically made of aluminum or cast iron.

Question 3

Technician A says transmission lip seals are made from neoprene. Technician B says transmission o-rings are made from neoprene rubber. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct as transmission lip seals and o-rings can be made from neoprene rubber.

Question 4

When a gear is selected in a conventional automatic transmission, how is the input shaft torque delivered to the turning members of the planetary gear sets?

Accepted Answer

The answer of When a gear is selected in a...

Question 5

Which of the following is found in a valve body?

Accepted Answer

A valve body can contain check valves, orifices, and spool valves, as they are all components used to control fluid flow within a hydraulic or pneumatic system.

Question 6

Which of the following is least likely to be used as a servo piston seal?

Accepted Answer

Locking seals are not typically used as servo piston seals, as they are designed for different applications that require a more permanent seal. Neoprene and Teflon are more common materials for seals due to their flexibility and resistance to various conditions.

Question 7

Which of the following is most likely to be used with an automatic transmission?

Accepted Answer

A flexplate is used in automatic transmissions to connect the engine to the torque converter, replacing the flywheel used in manual transmissions.

Question 8

Technician A says thrust washers are a friction type of bearing. Technician B says thrust bearings are a type of flat needle roller bearing. Who is correct?

Accepted Answer

Thrust bearings are a type of flat needle roller bearing that is used to support axial loads. Thrust washers are a type of friction bearing that is used to reduce friction between two surfaces.

Question 9

A band has a _______ layer of friction material bonded onto spring steel or cast steel backing.

Accepted Answer

A band typically has a thin layer of friction material bonded onto a steel backing to provide the necessary grip and flexibility.

Question 10

Fluid can be trapped at the outer portion of the clutch cylinder due to centrifugal force. What prevents this from happening?

Accepted Answer

A centrifugal relief valve in the clutch piston or drum prevents fluid from being trapped at the outer portion of the clutch cylinder by allowing excess fluid to escape, counteracting the effects of centrifugal force.

Question 11

Which of the following is typically the output of a reed switch?

Accepted Answer

The answer of Which of the following is typically the...

Question 12

Modern automatic transmission cases are made of:

Accepted Answer

Modern automatic transmission cases are typically made of lightweight aluminum due to its strength, durability, and reduced weight, which improves fuel efficiency.

Question 13

Choose the correct statement with respect to the function of a flexplate and its components.

Accepted Answer

The answer of Choose the correct statement with respect to...

Question 14

Choose the correct statement.

Accepted Answer

The drum is splined to the sun gear, ring gear, or the planet carrier in a transmission system to facilitate the transfer of torque and rotational motion.

Question 15

Tech A states that some vehicles will include a transmission fluid warmer to help prevent wear in the transmission. Tech B states that all transmissions will have a transmission fluid cooler. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Some vehicles will include a transmission fluid warmer to help prevent wear in the transmission, and all transmissions will have a transmission fluid cooler.

Question 16

Technician A says that multi-plate clutches must have a specified amount of clearance when they are installed. Technician B says that there should be no clearance when they are installed because the clutch would slip. Who is correct?

Accepted Answer

Multi-plate clutches require a specified amount of clearance to ensure proper engagement and disengagement. Without this clearance, the clutch may not function correctly.

Question 17

Which of the following statements is NOT true regarding the transmission pan?

Accepted Answer

The transmission pan is removable to allow access for maintenance and repairs, such as changing the transmission fluid and filter.

Question 18

Technician A says that a manual transmission utilizes a flywheel and an automatic transmission utilizes a flexplate. Technician B says that a flexplate can be lighter than a flywheel. Who is correct?

Accepted Answer

Technician A is correct because manual transmissions use a flywheel to connect the engine to the transmission, while automatic transmissions use a flexplate. Technician B is also correct because flexplates are generally lighter than flywheels, as they do not need to store as much rotational energy.

Question 19

The __________ is the major control for the automatic transmission.

Accepted Answer

The valve body is the major control component in an automatic transmission, directing hydraulic fluid to various valves to control gear shifting.

Question 20

Technician A says that the valve body on a rear wheel drive vehicle may be found in the lower transmission pan. Technician B says that the valve body on a front wheel drive vehicle may be found behind the side transmission pan. Who is correct?

Accepted Answer

Technician A is correct because in rear-wheel-drive vehicles, the valve body is typically located in the lower transmission pan. Technician B is also correct because in front-wheel-drive vehicles, the valve body can be found behind the side transmission pan.
