Question 1

While disassembling the transmission, you can discover clues as to why a transmission failed in the first place, enabling you to correct the problems.

Accepted Answer

Disassembling a transmission allows for inspection of its components, which can reveal wear, damage, or failure points that indicate the cause of the malfunction.

Question 2

When disassembling an automatic transmission, the best practice is to disassemble, clean and inspect every possible part at once so that you can make a complete parts list of required components.

Accepted Answer

Disassembling, cleaning, and inspecting every part at once can lead to confusion and misplacement of parts. It's better to work in stages, documenting and organizing parts as you go to ensure accuracy and avoid errors.

Question 3

Having a transmission part hit the shop floor can cause damage that will require replacement of that transmission part.

Accepted Answer

Dropping a transmission part on the shop floor can cause physical damage such as dents, cracks, or misalignment, which may necessitate its replacement to ensure proper function.

Question 4

Always follow the vehicle manufacturer's recommended transmission disassembly and service procedures to prevent injury.

Accepted Answer

Following the manufacturer's recommended procedures ensures safety and prevents damage to the vehicle or injury to the person performing the service.

Question 5

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 allow for in-vehicle repair using special tools.

Question 6

On high-mileage vehicles, the clutches and steels can sometimes wear grooves into the sides of the automatic transmission case.

Accepted Answer

The repetitive motion and pressure from the clutches and steels in high-mileage vehicles can cause wear and grooves in the transmission case over time.

Question 7

Technician A says while disassembling the transmission, you can discover clues as to why a transmission failed. Technician B says you should quickly tear apart a transmission and begin cleaning the parts. Who is correct?

Accepted Answer

Technician A is correct because examining the transmission during disassembly can provide insights into the cause of failure, which is crucial for accurate diagnosis and repair.

Question 8

Technician A says during transmission overhaul all fluid passages must be inspected for debris by blowing them out with compressed air. Technician B says that during transmission overhaul each sprag must be fully disassembled and checked for damage. Who is correct?

Accepted Answer

The answer of Technician A says during transmission overhaul all...

Question 9

Technician A says always inspect the transmission case for damage or warping and ensure the vent is unclogged. Technician B says always inspect bands for damage, wear, or burns. Who is correct?

Accepted Answer

Both technicians are correct as inspecting the transmission case and bands are essential steps in transmission maintenance and repair.

Question 10

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.

Question 11

Which of the following practices should be followed when disassembling an automatic transmission?

Accepted Answer

Disassembling the transmission one unit assembly at a time helps in keeping track of parts and ensures proper reassembly.

Question 12

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 13

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 provide valuable insights into the cause of transmission failure, which is crucial for accurate diagnosis and repair.

Question 14

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, while inspecting bands is necessary to ensure they are in good condition for effective operation.

Question 15

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

Transmission assemblies often have large return springs requiring specialty tools for compression, and small parts can be easily lost if not handled carefully.

Question 16

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. Technician B's definition of free play is incorrect.

Question 17

Technician A says while disassembling the transmission, you can discover clues as to why a transmission failed. Technician B says you should quickly tear apart a transmission and begin cleaning the parts. Who is correct?

Accepted Answer

Technician A is correct because disassembling the transmission allows you to inspect the parts and identify any signs of wear or damage that may have contributed to the failure.

Question 18

Technician A says always inspect the transmission case for damage or warping and ensure the vent is unclogged. Technician B says always inspect bands for damage, wear, or burns. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. Inspecting the transmission case for damage or warping and ensuring the vent is unclogged is important for proper transmission function. Similarly, inspecting bands for damage, wear, or burns is crucial for maintaining transmission performance.

Question 19

Which of the following practices should be followed when disassembling an automatic transmission?

Accepted Answer

Disassembling the transmission one unit assembly at a time helps in keeping track of parts and ensures that each component is inspected and cleaned properly without causing confusion or misplacement of parts.

Question 20

Technician A says during transmission overhaul all fluid passages must be inspected for debris by blowing them out with compressed air. Technician B says that during transmission overhaul each sprag must be fully disassembled and checked for damage. Who is correct?

Accepted Answer
