Manual trans unit 3.
When discussing current trends in manual transmissions,Technician A says that six- and seven-speed transmissions reduce fuel economy because of the weight of their extra parts.Technician B says that some manual transmissions are shifted by internal solenoids and do not require a shift lever.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERb. B only While discussing shift forks,Technician A says most shift forks have two fingers that ride in the grooves on the outside of the speed gears.Technician B says each shift rail has three notches, which a spring-loaded ball or plunger rides in to give a detent feel to the shift lever and locates the proper position of the shift fork.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERb. B only When discussing shift mechanisms,Technician A says that the detent system prevents the engagement of more than one gear at a time.Technician B says that the interlock system places the shift rail and fork in an exact position.Who is correct? a. A only
b. B only c. Both A and B d. Neither A nor B - ANSWERd. Neither A nor B When discussing overdrive gears,Technician A says that the typical ratio is 0.70 to 0.90:1.Technician B says that the typical ratio is 1.0:1.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERa. A only While discussing reverse gear,Technician A says if the transmission has a synchronized reverse gear, the reverse synchronizer sleeve moves to engage with reverse gear. Power comes in through the input shaft, into the counter gear, through the reverse idler gear, and into the reverse gear on the main shaft. The reverse gear rotates the synchronizer sleeve, which rotates the hub and main shaft in a reverse direction.Technician B says if reverse is a nonsynchronized gear, a reverse-gear shift relay lever slides the reverse idler gear into contact with the countershaft reverse gear and the reverse gear on the output shaft. The reverse idler gear causes the reverse output shaft gear to rotate counterclockwise.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERc. Both A and B When discussing the operation of a synchronizer,Technician A says that the synchronizer inserts force the blocking ring against the conical face of the
d. Neither A nor B - ANSWERc. Both A and B While discussing synchronizers,Technician A says that in automotive transmissions, the commonly used type of synchronizer is the block type.Technician B says that triple-cone synchronizers are not as effective because they are smaller than single-cone synchronizers.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERa. A only While calculating the first gear ratio of a five-speed transmission,Technician A says to first divide the number of teeth on the front of the counter gear by the number of teeth on the clutch gear.Technician B says to next divide the number of teeth on the first-speed gear by the number of teeth on the matching counter gear and then multiply the ANSWER from the first set by the second.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERc. Both A and B All of the following gears have synchronizers except: Fifth. Reverse. First. Second. - ANSWERReverse.
The synchronizer is made up of the hub, _________, inserts, lock rings and blocking rings. main shaft sleeve gear friction disc - ANSWERsleeve Synchronizers lock the drive gears to the output shaft. a. True b. False - ANSWERa. True Which of the following is not a type of synchronizer: Pin type. Plain type. Block type. Ramp type. - ANSWERRamp type. The most common type of synchronizer is the Ramp type. a. True b. False - ANSWERb. False The _________ is (are) splined to the main shaft. blocking ring inserts hub sleeve - ANSWERblocking ring
a. True b. False - ANSWERb. False When inspecting the synchronizers of a transaxle,Technician A says that if the dog teeth of the synchronizer are slightly rounded, the synchronizer assembly must be replaced.Technician B says that the sliding movement of the synchronizer sleeve on the output shaft should be checked.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERd. Neither A nor B When disassembling a transaxle, a severely worn second gear synchronizer blocker ring is found.Technician A says that this should have caused the transaxle to jump out of gear.Technician B says that this should have caused difficult shifting into second gear.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERb. B only Transmission fluid level and type are being discussed.Technician A says that the proper fluid level for a transmission is normally to the bottom of the filler hole.Technician B says that most modern manual transmissions require heavy gear lube for proper operation.Who is correct? a. A only b. B only c. Both A and B
d. Neither A nor B - ANSWERa. A only When discussing transmission disassembly,Technician A says that the alignment of the parts of each synchronizer must be marked prior to disassembling the synchronizer assembly.Technician B says that most synchronizer hubs are splined to the shaft and are pressed on and off the shaft.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERc. Both A and B When inspecting a transaxle's gears,Technician A says that a shiny wear pattern on the center of the gear teeth is normal.Technician B says that it is normal for a reverse idler gear to have small chips on its engagement side.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERc. Both A and B When discussing shift problems,Technician A says that worn or broken engine and transaxle mounts can cause a transaxle to have shifting problems.Technician B says that poor shift boot alignment can cause a transaxle to jump out of gear.Who is correct? a. A only b. B only c. Both A and B
When discussion transmission repair,Technician A says that every part of a disassembled transmission should be carefully inspected, regardless of the problem.Technician B says that if the lubricant had traces of gold in it, it is likely that the gears will be severely worn.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERa. A only When discussing shift linkages,Technician A says that occasionally the internal shift linkage of some manual transaxles may need to be adjusted.Technician B says that worn external shift linkage may cause excessive clutch pedal free play.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERd. Neither A nor B A vehicle equipped with a five-speed manual transmission sometimes jumps out of direct (fourth) gear.Technician A says that this may be caused by worn cluster gear teeth.Technician B says that a worn main shaft pilot bearing could cause this problem.Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B - ANSWERb. B only
Which of the following is the first step in diagnosing a transmission concern: a. Visual inspection. b. Verify the customer's complaint. c. Refer to the Diagnostic Chart. d. Check for service bulletins. - ANSWERb. Verify the customer's complaint. A growling noise in a transmission is an indication of: a. A bad bearing b. A broken gear tooth c. A chipped gear tooth d. Worn gear teeth - ANSWERa. A bad bearing Incorrect clutch adjustment can cause which of the following: a. Hard shifting b. Any of these c. Grinding while shifting d. Gear clash - ANSWERb. Any of these
