Question 1

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 crucial during assembly.

Question 2

When installing valve body bolts:

Accepted Answer

It is important to look up torque specifications and torque sequences to ensure the valve body bolts are installed correctly and to prevent damage.

Question 3

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

Accepted Answer

B

Question 4

When installing the reaction planetary carrier down into the reaction ring gear, what should be done for the carrier to fit down into the transmission?

Accepted Answer

Rotating the planet gears helps align them with the ring gear, allowing the carrier to fit properly into the transmission without forcing it.

Question 5

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 on the inside of the planetary carrier.

Question 6

Which of the following tools is used after the new input shaft seals are installed and before the reverse input drum is ready to be installed?

Accepted Answer

The seal resizing tool is used to ensure that the new seals are properly sized and seated before installing the reverse input drum.

Question 7

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 with the most current and accurate information, which can prevent potential issues and ensure optimal performance.

Question 8

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 9

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 10

Tech A states that some components may have a torque sequence. Tech B states that some transmission components will have a two-step torqueing process for certain bolts. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Some components do require a specific torque sequence to ensure proper installation and function, and certain bolts, especially in transmissions, may require a two-step torqueing process to ensure they are tightened correctly.

Question 11

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 12

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 before assembly.

Question 13

Tech A states that on some transmissions it might be necessary to place components in a freezer to allow them to contract slightly. Tech B states that on some transmissions it might be necessary to place components in hot water to allow them to expand slightly. Who is correct?

Accepted Answer

Both Tech A and Tech B are correct. Cooling components in a freezer can cause them to contract, making it easier to fit them into place. Similarly, heating components in hot water can cause them to expand, which can also be useful in certain assembly or disassembly processes.

Question 14

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, as installing them after reassembly can be difficult and may lead to improper sealing.

Question 15

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 16

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 17

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 use in assembling transmission components, including seals, to ensure proper lubrication and sealing during initial operation. Wheel bearing grease is not suitable for seals like the output shaft seal.

Question 18

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 19

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 movement.

Question 20

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.
