A3 Manual Transmissions Q & A

 
 
16. A vehicle has a vibration while driving forward that increases with vehicle speed. The least likely cause of this condition is:
A Undercoating on the driveshaft
B Worn U-joints
C Limited slip clutch
D Unbalanced tire
Answer C is correct. Limited slip clutches typically have problems while cornering.
 
 
17. Technician A says a clutch start switch is normally closed when the clutch pedal is released. Technician B says it is designed to complete a circuit between the ignition switch and the starter relay. 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. Like a brake switch it completes the circuit when the pedal is depressed.
 
 
18. Two technicians are discussing a clutch master assembly. Technician A says external leaks are due to the secondary seal. Technician B says hydraulic fluid is hygroscopic and tends to absorb moisture from the atmosphere. 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.
 
 
19. Two technicians are discussing flywheel resurfacing. Technician A says a mark should be placed on the flywheel and the crankshaft before removal. Technician B says if too much surface is removed from the flywheel damage will occur to the release bearing. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither A or B
Answer A is correct. A mark should be placed on the flywheel/crankshaft before removal.
 
 
20. Technician A says on a front wheel drive vehicle both inboard and outboard axle joints can make noise while accelerating. Technician B says the outboard CV-joints noise is more prominent while cornering. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither A or B
Answer C is correct. Both technicians are correct.
 
 
21. There is a chirping sound as the clutch pedal is depressed. Technician A says it could be a worn clutch release bearing. Technician B says the sound is likely a worn transmission synchronizer. 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 chirping clutch release or throw out bearing is most likely caused by a lack of lubrication.
 
 
22. Which type of bearing typically requires a preload.
A Ball Bearing
B Thrust
C Tapered Roller
D Needle
Answer C is correct. Tapered roller bearings require a preloads.
 
 
23. There is a squeal from the clutch housing when the clutch pedal is depressed all the way to the end of its travel. Technician A says this could be worn counter shaft bearings. Technician B says the squeal is likely a faulty pilot bearing. 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 weak pilot bearing will make the most noise when the pedal is completely depressed and the transmission input shaft and the engines crankshaft are rotating at different speeds.
 
 
24. Gold metal shavings are found in the oil after draining a 5 speed manual transaxle. Technician A says this is a normal condition. Technician B says this likely from chipped gear teeth. 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 of these technicians are correct.
 
 
25. A 4WD vehicles transfer case makes a popping sound in 4WD when accelerating from a stop. Which of these is the cause:
A Output Shaft Assembly
B Shift Motor
C Chain
D Clogged Vent
Answer C is correct. A stretched chain can make a popping or rattling sound. It may also cause damage to the case and other components.
 
 
26. A vehicle has an excessive vibration while driven at 55 mph. Technician A says this could be caused by pinion shaft companion flange run out. Technician B says says this could be caused by driveshaft run out. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer C is correct. Both technicians are correct.
 
 
27. An all wheel drive vehicle suffers from continuous viscous clutch failure. Which of the following is the cause?
A Front Universal Joints
B Overfilled Fluid
C Vehicle Speed Sensor
D Different Size Tires
Answer D is correct. The viscous clutch is designed to allow for differences in axle rotation. When forced to compensate for different tire sizes or inflation all the time the clutch is over worked and will wear prematurely.
 
 
28. A manual transaxle is suffering from clutch chatter. Technician A says that clutch chatter is caused by glazed clutch facings. Technician B says a worn pressure plate will cause clutch chatter. Who is correct?
A Technician A
B Technician B
C Both A and B
D Neither Technician A or B
Answer C is correct. Both technicians are correct.
 
 
29. The best tool for checking ring gear run out is a:
A Bore gauge
B Digital micrometer
C Dial indicator
D Straightedge and feeler gauge
Answer C is correct. A dial gauge is used to measure ring gear run out.
