A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

Technician A is correct because valves in the valve body are indeed operated by hydraulic and spring pressure. Technician B is also correct because if the valves do not move freely, it can lead to improper shifting of the vehicle.

Question 8

Multiple valves, solenoids, and sensors can be found in the valve body.

Accepted Answer

The valve body in an automatic transmission contains multiple valves, solenoids, and sensors that control the flow of hydraulic fluid to various parts of the transmission.

Question 9

Technician A says that when rebuilding an automatic transmission, the valve body requires no special service. Technician B says that when rebuilding an automatic transmission, the valve body never needs to be replaced. Who is correct?
A) Technician A
B) Technician B
C) Both technicians
D) Neither technician

Accepted Answer

The valve body in an automatic transmission often requires inspection, cleaning, and sometimes replacement during a rebuild, as it is a critical component that controls fluid flow and shifting.

Question 10

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?
A) Technician A
B) Technician B
C) Both A and B
D) Neither A nor B

Accepted Answer

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

Question 11

The clutch pack steels typically have splines, or teeth, on the inside edge to hold them to a member of the planetary gear set.

Accepted Answer

The clutch pack steels typically have splines or teeth on the outside edge to engage with the clutch drum, while the friction plates have splines on the inside edge to engage with the planetary gear set.

Question 12

What type of clutches are used to hold or drive individual members of the planetary set in an automatic transmission?
A) Single-disc dry clutch
B) Single-disc wet clutch
C) Multi-disc wet clutch
D) Multi-disc dry clutch

Accepted Answer

Multi-disc wet clutches are commonly used in automatic transmissions to hold or drive individual members of the planetary gear set due to their ability to handle high torque and dissipate heat effectively.

Question 13

What effect does adding more clutch plates and steels have on a multi-plate clutch in a transmission?
A) Increases the torque capacity of the clutch
B) Decreases the torque capacity of the clutch
C) Increases the clutch clearance
D) Either A or B, depending on the situation

Accepted Answer

Adding more clutch plates and steels increases the surface area for friction, which enhances the torque capacity of the clutch.

Question 14

Grooving of the clutch discs allows the fluid to escape from between the plates when the clutch engages and creates a firmer, quicker shift.

Accepted Answer

Grooving on clutch discs helps channel the fluid away, reducing slippage and allowing for a more direct and quicker engagement of the clutch plates.

Question 15

Multi-disc clutches are unique in that they not only can be used to hold a member of the planetary gear set, but they are also the only apply device that can be used to drive a member of the planetary gear set.

Accepted Answer

Multi-disc clutches are the only type of apply device that can be used to drive a member of the planetary gear set because they can transmit torque in both directions.

Question 16

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?
A) Through bands
B) Through sprags
C) Through clutches
D) All of the above

Accepted Answer

In a conventional automatic transmission, clutches are used to engage and disengage different gears by connecting the input shaft to the planetary gear sets, allowing torque to be delivered to the turning members.

Question 17

Which of the following is TRUE of clutches and steels in a multi-disc clutch?
A) The frictions are on one end of the clutch and the steels are on the other end
B) The steels and frictions are placed alternately into the clutch drum
C) The steels release the clutch and the frictions apply it.
D) The frictions release the clutch and the steels apply it

Accepted Answer

In a multi-disc clutch, the steels and frictions are placed alternately into the clutch drum to allow for effective engagement and disengagement.

Question 18

Which of the following are not used to release a multi-disc clutch?
A) A single large coil spring
B) Many small coil springs
C) A diaphragm spring
D) A bendix spring

Accepted Answer

A Bendix spring is not used in the release mechanism of a multi-disc clutch; it is typically associated with starter motors.

Question 19

Fluid can be trapped at the outer portion of the clutch cylinder due to centrifugal force. What prevents this from happening?
A) A centrifugal relief valve in the clutch piston or drum.
B) A spring loaded pressure relief valve in the piston
C) An accumulator built into the apply circuit
D) An aspiration valve that is opened electrically

Accepted Answer

A centrifugal relief valve in the clutch piston or drum prevents fluid from being trapped by allowing excess fluid to escape when centrifugal force pushes it outward.

Question 20

What determines the torque capacity of a multi-disc clutch?
A) The type of transmission fluid used
B) The total number of clutch plates used
C) The clutch pack clearance
D) The size of the return spring

Accepted Answer

The torque capacity of a multi-disc clutch is primarily determined by the total number of clutch plates used, as more plates increase the surface area for friction, enhancing the clutch's ability to transmit torque.
