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

A special bushing installation tool is usually needed to correctly install the front pump bushing without damaging it.

Accepted Answer

A special bushing installation tool is typically required to ensure the front pump bushing is installed evenly and without damage, as it provides the necessary alignment and pressure.

Question 3

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 4

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

Accepted Answer

Each bushing inside an automatic transmission should be inspected for scratches, scoring, and large pits to ensure proper function and longevity of the transmission.

Question 5

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 it necessary to replace all bushings to ensure proper function.

Question 6

Many internal automatic transmission bushings are a split ring bushing that must be installed carefully to prevent splitting the new bearing apart.

Accepted Answer

Many automatic transmission bushings are designed as split rings to allow for easier installation, but they must be handled carefully to avoid damaging them during the installation process.

Question 7

The technician should always use a bushing driver to install new bushings into an automatic transmission.

Accepted Answer

A bushing driver is a specialized tool designed to install bushings without damaging them or the surrounding components, ensuring a proper fit and function in an automatic transmission.

Question 8

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 the transmission components.

Question 9

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.

Question 10

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 blockages can affect the performance and functionality of the transmission system.

Question 11

When rebuilding an automatic transmission, check valves and/or check balls should be inspected for wear and damage.

Accepted Answer

Check valves and check balls are critical components in an automatic transmission, and inspecting them for wear and damage is essential to ensure proper function and prevent transmission failure.

Question 12

Piston on both accumulators and a servos should be inspected for cracks.

Accepted Answer

Regular inspection of pistons for cracks is essential in both accumulators and servos to ensure proper functioning and prevent potential failures.

Question 13

What purpose does painting a rebuilt transmission serve?

Accepted Answer

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

Question 14

A misplaced valve body bolt can cause catastrophic damage when the vehicle is started if the bolt protrudes into any of the rotating parts of the transmission from the valve body area.

Accepted Answer

A misplaced valve body bolt can interfere with the transmission's rotating parts, potentially causing severe damage when the vehicle is started.

Question 15

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 16

Automatic transmission parts may require lots of wiggling and turning when you are attempting to reassemble the transmission, but if you try to force them together, you will succeed only in damaging the parts.

Accepted Answer

Forcing automatic transmission parts together can cause damage due to their precise engineering and alignment requirements. Proper reassembly often requires careful manipulation rather than force.

Question 17

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 be used to lubricate lip seals.

Question 18

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. Free play refers to the movement allowed in a component before it engages, not specifically related to bearings locking up.

Question 19

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 20

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

Accepted Answer

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