Question 3

18)The ____________________ at the ends of the countergear control the amount of end clearance.

Answer 3

thrust washers

Question 4

12)The lubricant that will MOST-Likely leave no strings of grease when you put a small amount between two fingers and then spread them apart is:

A) ATF
B) non-fibrous grease
C) fibrous grease
D) varnish

Question 5

20)Before attempting to install the transmission, be sure that the ____________________ is seated correctly on its pivot.

Question 6

19)After all of the gears are assembled onto the mainshaft, gear clearance is checked at each of the gears. Normal clearance is ____________________ to 0.005".

Question 7

2)Transmission failure can result from abuse or shocks to the transmission.

Question 8

6)Which of the following is LEAST-Likely a symptom a transmission could have?

A) Gear clashing during a shift
B) Gravity bleeding
C) Hard shifting
D) Jumping out of gear

Question 9

4)When ordering parts from a dealer or parts store, you do not need to identify the transmission.

Question 10

11)All of the following statements are true EXCEPT:

A) when replacing a bearing, use a press and support the outside of the bearing with a bearing separator.
B) the drive gear for the VSS or speedometer is located on the output shaft.
C) synchro sleeves wear either on the outside edge of the tooth or on the inside, partway into the sleeve.
D) when synchros have experienced wear, the teeth on the corresponding gear could also be worn.

Question 11

9)While having a discussion, Technician A says that when blow-drying a bearing, you must allow it to spin. Technician B says that allowing it to spin is a bad idea. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 12

15)While having a discussion, Technician A says that you should never use the transmission bolts to draw the transmission into the clutch. Technician B says that the transmission should slide all the way in by hand. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 13

17)A short shaft can be used to keep the needle bearings in the countershaft. This shaft, called a(n) ____________________, is slightly shorter than the case.

Question 14

8)All of the following statements are true EXCEPT:

A) it is sometimes necessary to remove exhaust pipes before the transmission can be removed.
B) before the transmission can be removed, the driveshaft must be removed.
C) on an RWD vehicle, to gain easier access to the nuts that hold a shifter handle in place, remove the cross-member bolts.
D) sometimes heat is needed to expand a gear during disassembly or reassembly. The tool of choice for this is a torch rather than a heat gun, which can damage a gear if it is overheated.

Question 15

7)____ level is checked by removing the fill plug and inserting your little finger inside the hole.

A) Lubricant
B) Transmission fluid
C) Brake fluid
D) Antifreeze level

Question 16

3)Worn linkage, driving with a defective clutch, or wear resulting from extra-high mileage can cause transmission problems.

Question 17

14)Which of the following statements is LEAST-Likely true?

A) Gaskets are sometimes reusable.
B) A gasket that was working fine previously could leak after reassembly.
C) Silicone RTV should only be used when recommended.
D) Some gaskets are a specified thickness to provide the correct bearing end play or preload.

Question 18

13)The part that can MOST-Likely be used during transmission assembly to make reinstallation of the countershaft much easier is:

A) bearings
B) countergear
C) helical gear
D) dummy shaft

Question 19

10)The best way to test synchro operation is to test-drive the vehicle before you remove the ____.

A) clutch
B) ball joints
C) transmission
D) gearset

Question 23

25)Why should you oil rubber seals and O-rings during installation?

Question 24

21)What are some of the steps you should take before removing the transmission from a vehicle?

Question 25

24)Why do you think the drive gear for the VSS or speedometer does not need to be replaced often?
