Question 1

Synchronizing devices are normally used when shifting into _____.
A) forward gears
B) reverse
C) all gears
D) neutral

Accepted Answer

Synchronizing devices are typically used when shifting into forward gears to match the speed of the gears and ensure smooth engagement.

Question 2

Synchronizing devices in the transmission synchronize gears that are about to be _____.
A) locked
B) unlocked
C) stopped
D) started

Accepted Answer

Synchronizing devices are used to match the speed of different gears before they come into contact with each other. Locking in this context means that the gears are ready to engage with each other.

Question 3

A transaxle for a front-wheel drive car is usually mounted cross-wise with the engine.

Accepted Answer

This is true. The transaxle, which includes the transmission and differential, is typically mounted cross-wise with the engine in a front-wheel drive car. This design allows for better weight distribution and more space for passenger and cargo areas in the front of the vehicle.

Question 4

_____ is the trade name for a new gear change system from the United Kingdom that replaces normal synchronizers to provide a change in gear ratios without interrupting the flow of engine torque to the wheels.
A) Disc and plate
B) Zeroshift
C) Self-shifting
D) Overdrive

Accepted Answer

The trade name for the new gear change system from the United Kingdom that replaces normal synchronizers to provide a change in gear ratios without interrupting the flow of engine torque to the wheels is called ZeroShift.

Question 5

Technician A says blocking rings are often made of brass or bronze because of the high heat produced by friction. Technician B says some synchronizer rings can contain powdered metal, Kevlar, and organic frictional materials. Who is correct?
A) A only
B) B only
C) both A and B
D) neither A nor B

Accepted Answer

Blocking rings are often made of brass or bronze because of the high heat produced by friction, which is what Technician A stated. Technician B is also correct in stating that some synchronizer rings can contain powdered metal, Kevlar, and organic frictional materials. Therefore, both Technician A and B are correct.

Question 6

A _____ transmission is a constant mesh, collar shift transmission with synchronizers that equalize the speed of the shaft and gear before they are engaged.
A) sliding gear
B) collar shift
C) constant mesh
D) synchromesh

Accepted Answer

A synchromesh transmission has synchronizers that allow for smooth engagement of gears by equalizing the speed of the shaft and gear before they are engaged. Sliding gear, collar shift, and constant mesh transmissions do not have this feature, making them more prone to grinding and difficulty during gear changes.

Question 7

The forward gears of all current automotive transmissions are synchronized.

Accepted Answer

The forward gears of all current automotive transmissions are synchronized to match the speed of the input shaft to that of the output shaft, enabling smooth shifting without grinding the gears.

Question 8

A _____ transmission uses two or more shafts mounted in parallel, with sliding spur gears arranged to mesh with each other to provide a change in speed or direction.
A) sliding gear
B) collar shift
C) constant mesh
D) synchromesh

Accepted Answer

Sliding gear transmission uses sliding spur gears arranged to mesh with each other to provide a change in speed or direction. Collar shift and synchromesh transmissions both use a set of collars to engage and disengage gears while constant mesh transmission uses gears that are always in mesh.

Question 9

What is the most common type of synchronizer?
A) block
B) disc and plate
C) plain
D) pin

Accepted Answer

Block synchronizers are the most common type of synchronizer used in manual transmissions. They are simple in design and relatively inexpensive to manufacture. Block synchronizers consist of a synchronizer ring that is splined to the input shaft and a synchronizer hub that is splined to the output shaft. The synchronizer ring has a series of teeth that engage with the teeth on the synchronizer hub. When the input shaft and output shaft are rotating at different speeds, the teeth on the synchronizer ring and synchronizer hub will slip against each other, causing the synchronizer ring to move axially. This axial movement of the synchronizer ring will cause the teeth on the synchronizer ring to engage with the teeth on the output shaft, synchronizing the speeds of the input shaft and output shaft.

Question 10

All synchronizers use friction to synchronize the speed of the gear and shaft before the connection is made.

Accepted Answer

This is because synchronizers have friction surfaces that help match the speed of the gear and shaft, allowing for smooth engagement of gears.

Question 11

_____ in a transmission that must be meshed to obtain reverse gear; it is used only in reverse, and does not transmit power when the transmission is in any other position?
A) Counter gear
B) Reverse idler gear
C) Reverse drive gear
D) First gear

Accepted Answer

The reverse idler gear is the gear in a transmission that is meshed to obtain reverse gear. It is specifically designed to be used only in reverse and does not transmit power when the transmission is in any other position. Counter gear, reverse drive gear, and first gear are not specifically designed for reverse gear and can transmit power in other positions as well.

Question 12

When the transmission is in overdrive, the input shaft is turning faster than the output (main shaft).

Accepted Answer

In overdrive, the output shaft (main shaft) turns faster than the input shaft, allowing the vehicle to maintain speed while reducing engine RPMs, which improves fuel efficiency.

Question 13

In a typical five-speed transmission, there are five synchronizers.

Accepted Answer

In a typical five-speed transmission, there are usually only four synchronizers, as the first gear and reverse do not typically require synchronization due to their design and usage patterns.

Question 14

_____ synchronizers consist of a hub (called a clutch hub), sleeve, blocking ring, and inserts or spring-and-ball detent devices.
A) Block
B) Disc and plate
C) Plain
D) Pin

Accepted Answer

Block synchronizers have a hub, sleeve, blocking ring, and inserts or spring-and-ball detent devices. Disc and plate synchronizers have a hub, disc carrier, and alternating friction discs and metal plates. Plain synchronizers have no blocking mechanism and rely on friction for synchronization. Pin synchronizers use small pins to align the gears during shifts.

Question 15

A _____ transmission has parallel shafts fitted with gears in constant mesh.
A) sliding gear
B) collar shift
C) constant mesh
D) synchromesh

Accepted Answer

The answer of A _____ transmission has parallel shafts fitted...

Question 16

Torque may be described as twisting power.

Accepted Answer

Torque is defined as the force that causes an object to rotate around an axis, which can be described as twisting power.

Question 17

RWD and transaxle cars use the same type of differentials.

Accepted Answer

RWD (Rear Wheel Drive) vehicles typically use a traditional differential located in the vehicle's rear axle, while transaxle cars, which are often FWD (Front Wheel Drive) or AWD (All Wheel Drive), integrate the differential into the transaxle assembly, which combines the transmission, differential, and axle into a single unit. The design and operation of these differentials can vary significantly between RWD and transaxle configurations.

Question 18

The two separate shafts in a transaxle are called _____ shafts.
A) input and output
B) horizontal and vertical
C) forward and reverse
D) synchromesh

Accepted Answer

The two separate shafts in a transaxle are commonly referred to as the input shaft (where power is introduced from the engine) and the output shaft (where power is sent to the wheels).

Question 19

The use of incorrect transmission fluid is unlikely to impact shift quality.

Accepted Answer

Using incorrect transmission fluid can cause damage to the transmission and ultimately lead to poor shift quality. The proper type of fluid specified by the manufacturer should always be used.

Question 20

Advanced synchronizer designs may use multiple cones to increase the capacity of the unit while making it smaller.

Accepted Answer

This is true. Multiple cones in a synchronizer design can increase its capacity while reducing its size.
