Question 1

The extension housing seal is considered an internal transmission seal.

Accepted Answer

The extension housing seal is considered an external transmission seal as it is located at the rear of the transmission where the driveshaft connects.

Question 2

Which of the following seal designs are made from neoprene rubber and are often found sealing stationary parts of the transmission, such as a speedometer cable assembly or governor cover.

Accepted Answer

O-ring seals are commonly made from neoprene rubber and are used to seal stationary parts in various applications, including transmission components like speedometer cable assemblies or governor covers.

Question 3

Transaxles may have a second pan fitted somewhere other than the bottom of the transmission that encloses the valve body. What is that pan commonly called?

Accepted Answer

The pan that encloses the valve body on a transaxle and is not located at the bottom is commonly referred to as the "side pan."

Question 4

The bottom transmission pan is often removed during routine transmission fluid service to change the filter and clean a magnet, if equipped, located inside the pan that catches small particles of steel and iron that are floating in the fluid.

Accepted Answer

The bottom transmission pan is removed during routine service to access the filter and clean the magnet that collects metal particles, ensuring the transmission fluid remains clean.

Question 5

Technician A says modern automatic transmission cases are made of lightweight aluminum and alloys. Technician B says on the rear or output side of the transmission, there is a housing called the extension housing. Who is correct?

Accepted Answer

Modern automatic transmission cases are indeed made of lightweight aluminum and alloys, and the extension housing is a component found on the rear or output side of the transmission.

Question 6

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

The majority of automatic transmission control valves are indeed located inside the valve body, and typical valve bodies are made of materials like aluminum or cast iron.

Question 7

Which of the following can be found in a valve body?

Accepted Answer

A valve body can contain check valves, orifices, and spool valves, as these are all components that can be part of a valve system.

Question 8

Which of the following is found in a valve body?

Accepted Answer

A valve body can contain check valves, orifices, and spool valves, as these components are integral parts of various types of valve systems.

Question 9

Which of the following are NOT external transmission components?

Accepted Answer

All the listed components (Case, Extension, Pan) are external parts of a transmission system.

Question 10

A transmission painted a particular color indicates which of the following?

Accepted Answer

The answer of A transmission painted a particular color indicates...

Question 11

A transmission pan holds about half of the total transmission fluid.

Accepted Answer

The transmission pan typically holds about half of the total transmission fluid, with the rest circulating through the transmission system.

Question 12

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

Accepted Answer

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

Question 13

Some transmissions use variable displacement pumps to reduces the pumping load on the engine when the transmission requires less fluid to be pumped. Which of the following pump designs are used as variable displacement pumps?

Accepted Answer

The answer of Some transmissions use variable displacement pumps to...

Question 14

In the variable displacement pump, the pump housing can pivot in relation to the rotor.

Accepted Answer

In a variable displacement pump, the pump housing or swashplate can pivot to change the angle relative to the rotor, allowing for adjustment of the pump's displacement and flow rate.

Question 15

What part can directly drive the front pump of an automatic transmission?

Accepted Answer

The torque converter is directly connected to the engine and drives the front pump of an automatic transmission, providing the hydraulic pressure needed for the transmission to operate.

Question 16

Which of the following two materials are most commonly used to make transmission pump housings?

Accepted Answer

Cast iron is the most common material used for transmission pump housings due to its strength, durability, and relatively low cost. Aluminum is also commonly used due to its light weight and corrosion resistance.

Question 17

Which of the following is a common name for the primary automatic transmission oil pump?

Accepted Answer

The front pump is commonly referred to as the primary automatic transmission oil pump, as it is located at the front of the transmission and is driven by the engine.

Question 18

Which of the following statements is TRUE about cast iron pump housings?

Accepted Answer

Cast iron pump housings are known for their durability and resistance to wear, they typically require less frequent replacement compared to aluminum, and they are indeed heavier than aluminum.

Question 19

What kind of pump uses a spring-loaded movable pump housing that pivots in such a way that the volume of the pumping chambers can be increased or decreased based on fluid pressure.

Accepted Answer

A variable displacement vane pump uses a spring-loaded movable pump housing that pivots to adjust the volume of the pumping chambers based on fluid pressure, allowing for variable displacement.

Question 20

Technician A says a rotor pump has a center rotor that is driven by the torque converter. Technician B says a vane pump may be either a positive or variable displacement pump. Who is correct?

Accepted Answer

Technician A is correct because a rotor pump can have a center rotor driven by the torque converter. Technician B is correct because a vane pump can be designed as either a positive displacement or variable displacement pump.
