Question 1

When the 1-2 shift rail is moved into first gear, the 3-4 and 5-R shift rails are prevented from moving by the ______.

Accepted Answer

The interlock pin is designed to prevent the 3-4 and 5-R shift rails from moving when the 1-2 shift rail is engaged in first gear, ensuring that only one gear can be engaged at a time to prevent transmission damage.

Question 2

A 2.85:1 ratio represents a gear ____________________.

Accepted Answer

The answer of A 2.85:1 ratio represents a gear ____________________....

Question 3

All gear changes pass through the ____________________ position.

Accepted Answer

The answer of All gear changes pass through the ____________________...

Question 4

Which of the following is NOT one of the basic manual transmission shafts?

Accepted Answer

The basic manual transmission typically includes an input shaft, countershaft, and mainshaft. The transfer shaft is not considered one of the basic manual transmission shafts; it is more commonly associated with four-wheel drive systems for transferring power to the axles.

Question 5

A 1:1 ratio is called ____________________ drive.

Accepted Answer

The answer of A 1:1 ratio is called ____________________ drive....

Question 6

Final drive ratios are being discussed. Technician A says that the final drive ratio is the gear ratio of the ring gear and pinion gear in a rear axle. Technician B says the final drive ratio is the gear ratio of the pinion gear and ring gear in a transaxle. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. The final drive ratio refers to the gear ratio between the ring gear and pinion gear, whether it's in a rear axle or a transaxle.

Question 7

Blocking rings are being discussed. Technician A says that during a gear shift, the blocking ring is pushed into the speed gear cone by the shifter plates or keys. Technician B says the blocking ring eliminates friction between the cone-shaped surface on the speed gear and the synchronizer assembly. Who is correct?

Accepted Answer

Technician A is correct because during a gear shift, the blocking ring is indeed pushed into the speed gear cone by the shifter plates or keys to help synchronize the speeds. Technician B is incorrect because the blocking ring does not eliminate friction; it actually uses friction to help synchronize the speeds of the gears.

Question 8

The reverse lockout system prevents shifting the transmission into reverse when the vehicle speed exceeds ______ mph.

Accepted Answer

The reverse lockout system is designed to prevent accidental shifting into reverse at speeds typically above 12 mph to protect the transmission and ensure vehicle safety.

Question 9

A gear ratio of 0.80:1 is a(n)_____ ratio

Accepted Answer

An overdrive gear ratio is any ratio where the output speed is higher than the input speed, which is the case for a 0.80:1 ratio, indicating the output gear rotates faster than the input gear.

Question 10

Shift linkages are being discussed. Technician A says cables are used to connect the shift lever to the transmission. Technician B says rods are used to connect the shift lever to the transmission. Who is correct?

Accepted Answer

Both cables and rods can be used to connect the shift lever to the transmission, depending on the vehicle's design.

Question 11

A(n)____________________ contains the transmission and the final drive gear assembly.

Accepted Answer

The answer of A(n)____________________ contains the transmission and the final...

Question 12

Which of the following is not part of a synchronizer assembly?

Accepted Answer

The interlock pin is not part of a synchronizer assembly. It is instead used in the gearbox to prevent multiple gears from being engaged simultaneously. The synchronizer assembly typically includes the blocking ring, synchronizer hub, and shifting plates or keys, which work together to synchronize the speeds of the gears before engagement.

Question 13

Gear ratios are being discussed. Technician A says higher gear ratios allow for higher vehicle speeds and more torque. Technician B says lower gear ratios provide less torque and reduce vehicle speed. Who is correct?

Accepted Answer

Higher gear ratios provide more torque but reduce vehicle speed, while lower gear ratios allow for higher vehicle speeds but provide less torque. Both technicians are incorrect in their statements.

Question 14

Technician A says the main gears are also called speed gears. Technician B says speed gears freewheel around the mainshaft until they are locked to it by the engagement of their shift synchronizer unit. Who is correct?

Accepted Answer

Both statements are correct. The main gears in a transmission are indeed also referred to as speed gears, which correspond to the different speeds or gears the vehicle can be put into. Technician B is also correct in stating that these speed gears freewheel around the mainshaft until they are locked to it by the engagement of their shift synchronizer unit, which is how gear changes are smoothly facilitated in a manual transmission.

Question 15

The VSS [vehicle speed sensor] provides information for the ______.

Accepted Answer

The vehicle speed sensor (VSS) provides information to multiple systems, including the speedometer, cruise control system, and upshift lamp, making all the options correct.

Question 16

Technician A says spur gears have straight cut teeth. Technician B says helical gears have teeth cut at an angle. Who is correct?

Accepted Answer

Both statements are correct. Spur gears indeed have straight-cut teeth, while helical gears have teeth cut at an angle to provide smoother and quieter operation.

Question 17

Shifter linkages are being discussed. Technician A says the shifter interlock prevents the selection of more than one gear during shifting. Technician B says when one of the shift rails is moved by the shifter, the interlock pins hold the other shift rails in their neutral position. Who is correct?

Accepted Answer

Both Technician A and Technician B are correct. The shifter interlock mechanism is designed to prevent the selection of more than one gear at a time by locking the other shift rails in their neutral position when one is moved, ensuring smooth and safe gear transitions.

Question 18

When fourth gear is selected on a five-speed manual transmission, the synchronizer couples the ______.

Accepted Answer

The answer of When fourth gear is selected on a...

Question 19

Technician A says lower gears provide lower vehicle speeds but more torque. Technician B says higher gears provide less torque but higher vehicle speeds. Who is correct?

Accepted Answer

Both statements are correct. Lower gears indeed provide more torque and lower speeds, which is useful for situations requiring more power, such as climbing hills. Higher gears, on the other hand, provide less torque but allow the vehicle to achieve higher speeds, which is efficient for cruising at steady speeds on flat surfaces.

Question 20

Transmission shafts are mounted ____________________ to one another.

Accepted Answer

The answer of Transmission shafts are mounted ____________________ to one...
