Deck 122: Manual Transmissions/Transaxles

Question 1

Technician A says that the torque available at the output shaft is greater in second gear than when the transmission/transaxle is in third gear at the same engine speed. Technician B says that the output shaft is rotating faster when the transmission/transaxle is in second gear compared to third gear when the engine is at the same speed. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Answer 1

Technician A only

Question 2

The driving gear has 15 teeth and the driven gear has 29 teeth. Technician A says that the output gear will be going faster than the input gear. Technician B says the ratio is 3.86:1. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Answer 2

Neither technician A nor B

Question 3

Which part is splined to the clutch disc?

A)Main gear (input shaft)
B)Cluster shaft
C)Main shaft
D)Countershaft (lay shaft)

Answer 3

Main gear (input shaft)

Question 4

Two technicians are discussing how torque is increased inside a manual transmission/transaxle. Technician A says that the gear ratio in first gear between the main shaft and the countershaft should be multiplied by the ratio of the corresponding countershaft gear and output shaft gear. Technician B says that the two ratios should be added together. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 5

Which component cannot be removed before removing the transmission/transaxle from the vehicle?

A)Reverse light connector
B)Drive axle shafts
C)Front bearing retainer (quill)
D)Vehicle speed sensor

Question 6

Technician A says that snap rings are used to hold many components of a manual transmission/transaxle. Technician B says that snap rings have a "right side" that should always face up so that the snap ring pliers can be applied. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 7

A customer complained of hard shifting, particularly into first gear and reverse. Technician A says that the blocking ring maybe worn. Technician B says that the clutch may be defective or out of adjustment. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 8

Which part of a synchronizer is splined to a shaft?

A)Hub
B)Speed gear
C)Synchronizer sleeve
D)Synchronizer blocker ring

Question 9

A manual transmission is difficult to shift but only when the outside temperature is below freezing (32 F or 0 C) . Technician A says that the brass blocking ring could be defective. Technician B says that incorrect gear lubricant could be the cause. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 10

Which type lubricant is usually NOT used in a manual transmission/ transaxle?

A)SAE 80W-90 gear lube
B)Engine oil
C)High temperature chassis grease
D)ATF

Question 11

A five-speed transmission is in fourth gear. Which is correct?

A)The 3-4 synchronizer has engaged the input shaft gear
B)There is a 1:1 gear ratio
C)Both A and B
D)Neither A nor B

Question 12

A five-speed transmission is in third gear. Which is correct?

A)The 1-2 synchronizer is in neutral
B)The 3-4 synchronizer is moved to engage third gear
C)Both A and B
D)Neither A nor B

Question 13

Two technicians are discussing synchronizer rings. Technician A says that they equalize the speeds of the synchronizer assembly and the speed gear being engaged. Technician B says they block the synchronizer sleeve briefly during a shift. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 14

The cluster gear is supported by ________.

A)Roller bearings between the countershaft and the case
B)Bushings
C)Either A and B
D)Neither A nor B

Question 15

Some manual transmissions use ATF (automatic transmission fluid) as a lubricant.

Question 16

A four-speed transmission is making a grinding noise only while shifting into second gear. This could be caused by ________.

A)A faulty 1-2 synchronizer sleeve
B)A damaged main drive gear
C)Both A and B
D)Neither A nor B

Question 17

Two technicians are discussing a transmission that is noisy in first, second, third, and reverse but quiet in fourth gear. Technician A says there is probably a bad input shaft gear. Technician B says it probably has a faulty 1-2 synchronizer assembly because reverse is on the synchronizer sleeve. Which technician is correct?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Question 18

When one synchronizer is shifted into gear, the movement of the other shifter forks is blocked by the ________.

A)Detents
B)Interlocks
C)Both A and B
D)Neither A nor B

Question 19

The idler gear is used for which gear?

A)Reverse
B)Third
C)First
D)Second

Question 20

The detent mechanism inside a transmission is used to ________.
