Technician A
Technician B
Both A and B

Which of the following components are used to center and hold the shafts in a manual transmission?
Bearings

Sliding gears
Choose the correct statement:
The differential assembly does not allow the wheels on an axle to rotate at different speeds.
Technically, "differential assembly" is the other name for "final drive assembly."
The two varieties of differential assembly are open and closed.
Without the differential assembly, the tires would bind, skip, hop, and slide when going around a corner.
If the driven gear (the output gear) has more teeth than the drive gear (the input gear), then the gear set will have mechanical advantage because the smaller drive gear has to rotate faster than the larger driven gear, giving an increase in output force.
True
False
The dual mass flywheel has which of the following benefits?
Improves fuel economy
Absorbs engine vibrations
Both A and B
None of the above
An advantage of the coil spring pressure plate is that the more coil springs there are, the tighter the _______.
Flywheel bolts
Both A and B
Neither A nor B
Two technicians are discussing clutch free play. Technician A says an adjustment on the clutch cable provides for the specified amount of free play when the clutch pedal is in the released position. Technician B says free play is only present when the engine is running. Who is correct?
Technician A
Technician B
Both A and B
Neither A nor B
On a cable-operated clutch control system, the outer cable housing is fixed to the pedal support inside the vehicle and to the transmission bell housing in the engine compartment.
True
False

Gravity
Manual
Pressure
Vacuum
It is important to check the clutch linkage mechanism for proper operation and correct the adjustment (_______) periodically.

A relatively large twisting force must be applied to the wheels to accelerate the vehicle from a stop.
True
False
Each manual transmission selector shift rail has a detent mechanism, usually in the form of a spring-loaded ______ ball held in the casing.
Cast-iron
Aluminum
Steel
None of the above
Single-row, deep-groove ball bearings normally support the ______ in conventional rear-wheel drive manual transmissions.
Input shaft and reversing shaft
Main shaft and input shaft
Either A or B
Neither A or B
The flutes or swirls found in hydrodynamic seals create a pumping action as the input or output shaft rotates, causing any fluid at the sealing edge to be drawn back inside the casing.
True
False
All of the following statements are true EXCEPT:
pocket bearings sit in the pocket of the input shaft.
pocket bearings support the front of the input shaft.
pocket bearings are generally not used in rear-wheel drive transmissions.
pocket bearings are primarily used on countershafts.
When metal is found floating inside the transmission fluid, the technician knows that:
it is time to change the fluid.
the transmission will have to be pulled apart or replaced.
the transmission is leaking and needs to be sealed.
this condition is normal and nothing needs to be done.
Upon inspection of a failed manual transmission, it may be possible to find out what caused the failure of the transmission in the first place; for example, if the transmission shift linkage is keeping one gear ________, the dog teeth of the transmission can be damaged.
Partially engaged
In reverse
Both A and B
Neither A nor B
If found cheaper to replace a transmission after disassembly and inspection. What should be done with the old unit?
Reassemble it for core return.
Clean and bubble wrap the original parts.
Scrap the old parts.
Keep the old parts for reuse.

True
False
All the following tools will be needed in rebuilding a transmission EXCEPT a(n) ______. Select one:
Engine support tool
Dial bore gauge
Transmission holding fixture

When performing any kind of service to a manual transmission, the first task would be to: Select one:
steam clean the transmission.
check for stuck linkage.
obtain and read original equipment manufacturer (OEM) service information.
inspect the exterior of the vehicle.
All-wheel drive vehicles are intended for lighter duty and are sometimes referred to as "______." Select one:
Suburban vehicles
Chameleons
Boulevard SUVs
Avenue SUVs
Because the ______ are locked together at the transfer case, the difference in speed cannot be absorbed in the transmission, and the drivelines can be subjected to torsional binding because they are forced to rotate at the same rate of speed.
Which of the following is NOT a possible power transfer option for a driver to select in a vehicle equipped with a transfer case?
Four-wheel drive high range
Rear-wheel drive mid-range
Two-wheel drive
Neutral
When the fluid in a viscous coupling becomes heated, the fluid will:
thin out to lubricate better.
overheat and have to be changed.
not be affected by heat.
thicken to help coupling.
Each four-wheel drive type of driveshaft has a sliding joint (slip joint) incorporated into the shaft to accommodate changes in driveshaft length by allowing the driveshaft to slide on the splines of its counterpart.
True
False
When testing a four-wheel drive electronic component, the Technician will use a scan tool to pull codes, and then a ______ to diagnose any codes found.
