A3 Manual Transmissions Q & A

1. The bushing in the extension housing on a transmission is worn on one side. Technician A says this could be caused by binding U-joints. Technician B says this is more likely caused by excessive output shaft end-play. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer A. is correct. A binding U-joint is likely to damage both the bushing and the seal.
 
 
2. A chirping sound is heard when the clutch pedal is depressed. All of these could make this noise except the:
A Synchronizer Assembly
B Clutch Disc
C Input Shaft Bearing
D Release Bearing
Answer A is correct. A worn synchronizer assembly will cause grinding while shifting into that gear only.
 
 
3. Technician A says the collapsible sleeve may be loosened to achieve proper pinion bearing preload. Technician B says an inch pound torque wrench is used to check and adjust pinion bearing preload. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer B is correct. An inch pound torque wrench is used to check pinion bearing preload.
 
 
4. Two technicians are discussing drive line seals. Technician A says repeated extension housing seal failure could be caused by a pitted axle slip yolk. Technician B says a bent axle could cause axle seal leakage. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer C is correct. Repeated extension housing seal failure can be caused by a pitted slip yolk. A bent axle will also cause axle seal leakage.
 
 
5. Technician A says to should use a feeler gauge to check the clearance between the shift fork and the synchronizer sleeve. Technician B says a bent shift rail will cause hard shifting. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer C is correct. Use a feeler gauge to check the clearance between the shift fork and the synchronizer sleeve. A bent shift rail will cause hard or no shifting.
 
 
6. Two technicians are discussing a clutch pressure plate. Technician A says a pressure plate must be replaced if it is warped. Technician B says the pressure plate can be easily disassembled and repaired or resurfaced. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer A is correct. The pressure plate should be replaced if it is warped.
 
 
7. Limited slip differentials have all of the following characteristics except:
A Both wheels drive during acceleration.
B Chatter may occur from worn parts.
C They often use special fluids.
D Both wheels drive while cornering.
Answer D is correct. One wheel is allowed to slip while turning with a limited slip differential.
 
 
8. A front wheel drive vehicle makes a clicking sound when cornering. Technician A says this could be caused by the axles CV (constant velocity) joint. Technician B says it’s the half shafts torsional damper. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer A is correct. Bad or worn CV Joints make a clicking sound while cornering.
 
 
9. Technician A says a technician may replace the ring gear with out replacing the pinion gear as long as it checks out within specifications. Technician B says that ring gear run out is checked with a digital micrometer. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer D is correct. Neither Technician A or B are correct.
 
 
10. A manual transmission slips out of third gear. The most likely cause is:
A Worn bushings
B High fluid pressure
C Weak detent spring
D Worn shifter bushing
Answer C is correct. A worn detent spring will result in a transmission slipping out of gear.
 
 
11. The backup lights of a vehicle are inoperative. Technician A says the backup light switch may be stuck closed. Technician B says there may be a loose ground connection. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer B is correct. A loose ground connection could cause an inoperative circuit.
 
 
12. A manual transmission jumps out of gear. Technician A says loose shift linkage may be causing this problem. Technician B says worn motor mounts could cause this condition. Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer C is correct. Both technicians are correct.
 
 
13. A rear wheel drive vehicle with a limited slip differential chatters while turning corners. Technician A says the differential may have the wrong fluid. Technician B says the differential may have excessive pinion preload. Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer C is correct. Both technicians are correct.
 
 
14. Two technicians are discussing a vacuum operated transfer case. Technician A says a vacuum between 10Hg and 18Hg is required to operate this unit. Technician B says the vacuum operates a mode fork to switch between 2WD and 4WD. Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer B is correct. The mode fork switches the transfer case mode between 2WD and 4WD.
 
 
15. Two technicians are discussing a synchronizer assembly in a three speed manual transmission. Technician A says the splines on a synchronizer clutch sleeve should be pointed. Technician B says the teeth on a synchronizer sleeve and ring should be smooth and rounded. Who is correct?
A Technician A
B Technician B
C Both Technician A and B
D Neither Technician A or B
Answer A is correct. The splines on the clutch sleeve should be pointed.
