Question 1

Technician A says all components of the oil delivery circuit in an automatic transmission must be inspected for debris during a transmission rebuild. Technician B says that this is not necessary since all debris would be captured by the transmission filter. Who is correct?

Accepted Answer

Technician A is correct because during a transmission rebuild, it is important to inspect all components of the oil delivery circuit for debris to ensure proper function and prevent future issues. The transmission filter may not capture all debris, especially if it is lodged in other components.

Question 2

Technician A says you should coat lip seals with transmission assembly lube during installation to prevent damaging the seal. Technician B says you should use chassis grease to lubricate lip seals during installation to prevent damaging the seal. Who is correct?

Accepted Answer

Transmission assembly lube is specifically designed for use in transmission components and is appropriate for lubricating lip seals during installation. Chassis grease is not recommended for this purpose.

Question 3

When assembling the transmission, which of the following is installed last?

Accepted Answer

The answer of When assembling the transmission, which of the...

Question 4

All of the following statements are true with respect to end play except:

Accepted Answer

The answer of All of the following statements are true...

Question 5

End play can be corrected by:

Accepted Answer

End play can be corrected by installing select fit thrust washers of different thicknesses to adjust the clearance and limit the axial movement.

Question 6

Tech A states that an end play measurement that is too small can mean that you have excessive clearance in the clutch packs. Tech B states that an end play measurement that is too large means that the thrust washers are too big. Who is correct?

Accepted Answer

End play that is too small typically indicates insufficient clearance, not excessive clearance in clutch packs. End play that is too large usually suggests that thrust washers are too worn or small, not too big.

Question 7

All of the following statements with respect to case preparation are true except:

Accepted Answer

Seals should be installed before reassembly to ensure proper fit and function, not after reassembly.

Question 8

When installing manual shaft seals:

Accepted Answer

Ensuring that the manual shaft seal is straight during installation is crucial to prevent leaks and ensure proper function.

Question 9

Tech A states that proper transmission assembly is critical for the repair job to be successful. Tech B says that all components of the automatic transmission should have been rebuilt and/or inspected before the reassembly process begins. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Proper transmission assembly is crucial for a successful repair, and all components should be rebuilt or inspected before reassembly to ensure reliability and performance.

Question 10

Tech A states that seals should be lubricated with transmission assembly lubricant during assembly. Tech B states that wheel bearing grease should be used to lubricate seals such as the output shaft seal. Who is correct?

Accepted Answer

Transmission assembly lubricant is specifically designed for lubricating seals during assembly, ensuring proper sealing and function. Wheel bearing grease is not suitable for seals like the output shaft seal.

Question 11

All of the following statements are true with respect to final transmission assembly except:

Accepted Answer

Forcing transmission parts together can cause damage. Proper alignment and gentle fitting are necessary for assembly.

Question 12

When installing valve body bolts:

Accepted Answer

It is important to look up torque specifications and torque sequences to ensure proper installation and avoid damage.

Question 13

When installing a transmission, which of these is an alternate to using a support tool?

Accepted Answer

The answer of When installing a transmission, which of these...

Question 14

Which of the following should be installed after the planetary carrier is installed?

Accepted Answer

Low/reverse clutch components are installed after the planetary carrier is installed because they are located behind the planetary carrier in the transmission case.

Question 15

Tech A says that if you are familiar with a transmission it is not necessary to check for updates before assembling the transmission. Tech B says that you should always check for revised specifications and/or service updates before assembling the transmission. Who is correct?

Accepted Answer

Tech B is correct because checking for revised specifications and service updates is crucial to ensure that the transmission is assembled according to the latest standards and improvements, which can prevent potential issues and ensure optimal performance.

Question 16

Tech A says that it is fine to tighten bolts on a transmission using an air ratchet if you set the torque level low on the air ratchet. Tech B states that a torque wrench should always be used when torqueing bolts. Who is correct?

Accepted Answer

A torque wrench should always be used to ensure bolts are tightened to the manufacturer's specified torque settings, which an air ratchet cannot accurately provide.

Question 17

Tech A states that clutches should be soaked in the correct transmission fluid before installing them into transmission. Tech B states that clutches should be soaked for at least 15 minutes before installation. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Clutches should be soaked in the correct transmission fluid to ensure proper lubrication and function, and soaking them for at least 15 minutes is a common practice to ensure they are adequately saturated.

Question 18

Tech A says that a small amount of epoxy can be used to hold thrust washers in place. Tech B says that a small amount of transmission assembly lubricant can be used to hold check balls in place during transmission assembly. Who is correct?

Accepted Answer

The answer of Tech A says that a small amount...

Question 19

Tech A states that you should use a pick to line up all of the clutches and steels in a clutch pack before assembling the transmission. Tech B states that clutches and steels can be lined up by rotating and shaking them. Who is correct?

Accepted Answer

Tech B is correct because clutches and steels can be aligned by rotating and shaking them, which is a common practice to ensure proper alignment without the need for a pick.

Question 20

Technician A says that transmission end play can be adjusted with select fit thrust washers. Technician B says that transmission end play should be measured after the front pump is installed. Who is correct?

Accepted Answer

Transmission end play can be adjusted with select fit thrust washers, and it is typically measured after the front pump is installed to ensure accurate readings.
