Question 1

Technician A says both gear-type and chain-style transaxle assemblies never need to be inspected for wear. Technician B says valve bodies and valve body valves must be inspected for wear very carefully. Who is correct?

Accepted Answer

Technician B is correct because valve bodies and valve body valves are critical components that require careful inspection for wear to ensure proper transmission function. Technician A is incorrect as transaxle assemblies should be inspected for wear.

Question 2

Techncian A says preload refers to the amount of force placed on a bearing before any working load is exerted on the bearing. Technician B says free play refers to the amount that a bearing is able to move before hitting the bearing race. Who is correct?

Accepted Answer

Technician A is correct because preload is indeed the force applied to a bearing before any external load is applied. Technician B is also correct because free play refers to the movement allowed in a bearing before it contacts the race.

Question 3

Technician A says to always inspect the transmission case for damage or warpage and ensure the vent is unclogged when rebuilding an automatic transmission. Technician B says always inspect bands for damage, wear, or burns when rebuilding an automatic transmission. Who is correct?

Accepted Answer

Both technicians are correct. Inspecting the transmission case and vent is crucial to ensure proper function and prevent leaks or pressure issues. Inspecting bands for damage, wear, or burns is also essential to ensure the transmission operates smoothly and efficiently.

Question 4

Technician A says that all internal transmission work must be performed in a clean environment. Technician B says that even the smallest dirt or debris in a valve body can cause a valve in a valve body to stick in its bore. Who is correct?

Accepted Answer

Both technicians are correct. A clean environment is crucial for internal transmission work to prevent contamination, and even small debris can cause issues like sticking valves in the valve body.

Question 5

Technician A says while disassembling the transmission, by working carefully and being observant you can discover clues as to why a transmission failed. Technician B says you should quickly disassemble a transmission and begin cleaning the parts to save on time. Who is correct?

Accepted Answer

Technician A is correct because careful observation during disassembly can help identify the cause of transmission failure, which is crucial for proper diagnosis and repair.

Question 6

Technician A states that many transmission assemblies have large return springs that must be compressed with specialty tools. Technician B states that small transmission parts can be easily lost if the technician is not careful. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. Transmission assemblies often have large return springs that require specialty tools to compress safely, and small parts can indeed be easily lost if not handled carefully.

Question 7

Technician A says preload refers to the amount of force placed on a bearing before any load is on the bearing. Technician B says free play refers to the distance that a bearing is able to turn before locking up. Who is correct?

Accepted Answer

Preload is indeed the force applied to a bearing before any external load is applied, ensuring proper function and longevity.

Question 8

Which of the following terms refers to the amount of force placed on a bearing before any vehicle load is on the bearing?

Accepted Answer

Preload refers to the amount of force applied to a bearing before any external load is applied, ensuring that the bearing components are properly seated and reducing play.

Question 9

Which of the following terms refers to the amount that a bearing is able to move before hitting the bearing race?

Accepted Answer

Free play refers to the amount of movement a bearing can have before it contacts the bearing race.

Question 10

Technician A says that if there is excessive up and down play in the driveshaft, the extension housing bushing should be replaced. Technician B says that on many transmissions the extension housing has to be removed to replace the bushing, but on some older transmissions special pullers and installers could make this an in-vehicle repair. Who is correct?

Accepted Answer

Excessive up and down play in the driveshaft can indicate a worn extension housing bushing, so Technician A is correct. Technician B is also correct because, while many transmissions require the extension housing to be removed to replace the bushing, some older models can have the bushing replaced in-vehicle using special tools.

Question 11

Which of the following could provide comprehensive detailed information on the disassembly, rebuild, and reassembly of the transmission?

Accepted Answer

ATRA (Automatic Transmission Rebuilders Association) manuals are specifically designed to provide detailed information on the disassembly, rebuild, and reassembly of transmissions.

Question 12

When disassembling a transmission, it is good to disassemble it into its unit assemblies because it helps in all of the below except:

Accepted Answer

Disassembling into unit assemblies does not save workspace; it may actually require more space to organize and lay out the parts.

Question 13

Tech A says that if the case vent is plugged it can result in fluid leaks from the transmission. Tech B says that the case vent should be blown out with compressed air while the transmission is apart. Who is correct?

Accepted Answer

A plugged case vent can cause pressure build-up, leading to fluid leaks. Blowing out the vent with compressed air is a good maintenance practice when the transmission is apart.

Question 14

A transmission with too little end play could indicate:

Accepted Answer

Too little end play in a transmission often indicates incorrect assembly, as the components may not be aligned or spaced properly.

Question 15

Tech A says that an end play measurement should be performed before disassembling a transmission. Tech B says that it is not necessary to perform an end play measurementbefore disassembling the transmission because you will be rebuilding and replacing components that will affect the end play. Who is correct?

Accepted Answer

Performing an end play measurement before disassembling a transmission is important to diagnose any issues and to have a baseline measurement for comparison after reassembly.

Question 16

Choose the correct order of dismantling the external components.

Accepted Answer

The answer of Choose the correct order of dismantling the...

Question 17

Which of the following indicates that the bushings in the transmission may need to be replaced?

Accepted Answer

Excessive bronze material on the pan indicates wear of the bushings, which are often made of bronze.

Question 18

All of the following statements are true except:

Accepted Answer

The statement that the front pump must be removed before the TCC can be removed, or the solenoid will break, is not necessarily true for all transmission models.

Question 19

Tech A says that you should inspect all electrical connectors for corrosion during disassembly so that replacement parts can be located if needed. Tech B says that electrical connectors will not corrode because they are submerged in transmission fluid. Who is correct?

Accepted Answer

Electrical connectors can corrode over time due to exposure to moisture and other environmental factors, so inspecting them during disassembly is a good practice.

Question 20

Choose the correct statement with respect to main transmission disassembly.

Accepted Answer

The plastic thrust bearing should be placed in the parts bin after removal to ensure it is not lost and can be inspected or replaced if necessary.
