Question 1

Technician A says that painting a rebuilt transmission helps to identify it as being a rebuilt transmission. Technician B says that painting a rebuilt transmission prevents the housing from leaking due to case porosity. Who is correct?

Accepted Answer

The answer of Technician A says that painting a rebuilt...

Question 2

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, such as a vehicle load, is applied. It ensures that the bearing components are properly seated and reduces play.

Question 3

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 4

Which of the following bushings is most likely to be worn and need replacement during a transmission repair or overhaul?

Accepted Answer

Both the front pump and extension housing bushings are commonly subject to wear due to their roles in supporting rotating components and handling significant loads and stresses in the transmission system.

Question 5

Which of the following should you inspect each bushing inside an automatic transmission for?

Accepted Answer

Bushings inside an automatic transmission should be inspected for scratches, scoring, and large pits, as these can indicate wear or damage that may affect the transmission's performance.

Question 6

When may it be necessary to purchase a complete bushing replacement kit and replace every bushing inside the transmission?

Accepted Answer

High-mileage transmissions are more likely to have worn-out bushings due to extensive use, making a complete replacement necessary to ensure proper function and longevity.

Question 7

If thrust bearings or washers are worn, ______ movement of components inside the automatic transmission will be allowed, affecting their operation.

Accepted Answer

Worn thrust bearings or washers in an automatic transmission allow lateral movement, which can affect the alignment and operation of internal components.

Question 8

What should be used to check the thickness of a thrust washer, and the thickness should be compared to the vehicle manufacturer's specifications.

Accepted Answer

A micrometer is a precision measuring instrument used to measure small distances or thicknesses with high accuracy, making it suitable for checking the thickness of a thrust washer.

Question 9

When reinstalling _________ in an automatic transmission, apply a small amount of transmission assembly lube to hold them in place.

Accepted Answer

Both thrust bearings and thrust washers can benefit from a small amount of transmission assembly lube to hold them in place during reinstallation in an automatic transmission.

Question 10

Which of the following can be worn by metal check balls?

Accepted Answer

Metal check balls can wear both the valve body and the separator plate due to repeated contact and movement within the transmission system.

Question 11

Where should compressed air should be used to ensure each fluid passage is clear and unobstructed?

Accepted Answer

Compressed air should be used in all these components to ensure that each fluid passage is clear and unobstructed, as they all play a role in the proper functioning of a transmission system.

Question 12

What purpose does painting a rebuilt transmission serve?

Accepted Answer

Painting a rebuilt transmission can help identify it as having been rebuilt (A) and can also help seal the transmission after it has been cleaned (B).

Question 13

What problems may occur if you fail to torque parts correctly when reassembling an automatic transmission?

Accepted Answer

Failing to torque parts correctly can lead to premature transmission failure, customer dissatisfaction, and physical damage to the transmission components.

Question 14

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 15

Technician A says you should coat lip seals with transmission assembly lube. Technician B says you can use petroleum jelly to lubricate lip seals. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. Transmission assembly lube and petroleum jelly can both be used to lubricate lip seals to ensure proper installation and function.

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.

Question 17

What are the best tools to install a new transmission seal in the extension housing?

Accepted Answer

A seal installation tool and hammer are specifically designed for installing seals without damaging them, ensuring a proper fit and seal.

Question 18

On a rear-wheel drive vehicle, what needs to be removed to replace the extension housing bushing?

Accepted Answer

To replace the extension housing bushing on a rear-wheel drive vehicle, the drive shaft and the extension housing need to be removed.

Question 19

A ________ should be used to check the thickness of a thrust washer, and the thickness should be compared to the manufacturer's specification.

Accepted Answer

A micrometer is a precision measuring instrument used to measure small distances or thicknesses, such as the thickness of a thrust washer, with high accuracy.

Question 20

When reinstalling thrust bearings or washers in a transmission, apply a small amount of ______ to help hold it in place.

Accepted Answer

Transmission assembly lube is specifically designed to hold parts in place during assembly and provide initial lubrication, making it the appropriate choice for reinstalling thrust bearings or washers in a transmission.
