Tech A says that some manual transmissions use two input shafts and two clutches. Tech B says that many manual transmissions now use planetary gear sets. Who is correct?

tech a ,aka dual-clutch manual transmission which has two input shafts connected by to counter shafts, one couter shaft has gear 2,4,6 the other counter shaft has gear 1,3,5

A rough growling noise occurs when the vehicle is moving and the transmission is in the forward or reverse gear. The noise is not heard when the transmission is in neutral. Technician A says that the output shaft (main shaft) bearings may be faulty. Technician B that says the pilot bearing may be faulty. Who is correct?

tech b

The gear lube level is being checked in a manual transmission. Technician A says it should run out when the plug is removed. Technician B says that some transmissions use motor oil as gear lube. Who is correct?

tech b,

Tech A says that if a noise is caused by a set of worn gears, it will normally be loudest in that gear while driving under a load. Tech B says that if the bearings on the input shaft, countershaft, or main shaft are worn, either front or rear, a growling noise will result when stopped in gear. Who is correct?

tech a

Tech A says that in a conventional transmission, the gears freewheel around the main shaft until they are locked to it by the synchronizer. Tech B says that when not engaged, main shaft gears slide away from the counter gears until they are no longer in mesh. Who is correct?

tech a

Tech A says that the speeds at which two meshed gears turn depend on the number of teeth on each gear. Tech B says that if the driving gear has fewer teeth than the driven gear, the speed of the driven gear is faster. Who is correct?

tech a

Some differential/final drive assemblies, such as _______, require specially designed additives or fluid.

Limited-slip assemblies and Positraction assemblies

Tech A says that an overdrive gear ratio means the input gear turns faster than the output gear. Tech B says that overdrive ratios provide less torque output than underdrive ratios. Who is correct?

Tech b

The service consultant's check sheet will ask the customer a series of questions to help determine _____. When the noise is occurring Whether the noise is louder on acceleration or on deceleration Whether the noise is in a particular gear All of the above

all of the above

A car jumps out of gear into neutral when decelerating or going down hills. Technician A says that the shift lever and internal gearshift linkage should be checked. Technician B says that a detent spring could be broken. Who is correct?

both

Tech A says that a broken detent spring can cause the transmission to pop out of gear. Tech B says that a broken interlock pin can cause the transmission to go into two gears at the same time? Who is correct?

both

Tech A says that the countershaft assembly can be made up of several gears machined out of a single piece of steel. Tech B says that the countershaft assembly is driven by the gear on the input shaft and drives the gears on the main shaft. Who is correct?

both, main shaft is sometimes called output shaft. if one gear chips the whole countershaft must be replaced.
