Question 1

A standard transmission has a torque converter. An automatic transmission uses a flexplate and heavy steel flywheel instead.

Accepted Answer

A standard (manual) transmission does not have a torque converter. It uses a clutch, while an automatic transmission uses a torque converter instead of a clutch, which is why it requires a flexplate and heavy steel flywheel.

Question 2

Which of the following statements is LEAST-Likely true?

Accepted Answer

Fluid couplings do not contain a stator; the stator is a component of a torque converter that is used to redirect fluid flow and increase torque. Fluid couplings typically have simpler designs that allow for the transfer of rotational power through fluid but do not amplify torque in the same way torque converters do.

Question 3

An automatic transmission shifts automatically between gear ranges and does not require a manual clutch.

Accepted Answer

An automatic transmission uses a torque converter instead of a clutch to shift gears automatically.

Question 4

While having a discussion, Technician A says that a conventional automatic transmission uses sequence control in which the solenoid controls a typical spool-type shift valve that sends fluid to the clutch or servo. Technician B says it uses direct electronic control with PWM solenoid valves. Who is correct?

Accepted Answer

The answer of While having a discussion, Technician A says...

Question 5

In overdrive, the direct clutch drives the planetary carrier counterclockwise, causing the long pinions to walk counterclockwise around the held large sun gear.

Accepted Answer

In overdrive, the direct clutch typically engages components that result in an increased output speed relative to the input speed, but the specific direction of rotation (clockwise or counterclockwise) and the components involved (e.g., planetary carrier, pinions, sun gear) depend on the design of the transmission and the gear being engaged. The description provided mixes elements of planetary gear operation without accurately describing the function of components in an overdrive scenario.

Question 6

The ____________________ senses engine load and vehicle speed and adjusts the transmission's shift points and fluid pressures to match.

Accepted Answer

The answer of The ____________________ senses engine load and vehicle...

Question 7

The ____________________ support is a large splined support that extends out of the transmission's front pump body.

Accepted Answer

The answer of The ____________________ support is a large splined...

Question 8

The ____________________ provides a means of changing gear ratios by holding and turning members to get different results.

Accepted Answer

The answer of The ____________________ provides a means of changing...

Question 9

A(n) ____ combines two planetary gearsets to provide more gear ratio possibilities.

Accepted Answer

A compound planetary gearset combines two planetary gearsets, allowing for more gear ratio possibilities, which is essential for achieving different speeds and torque in transmissions.

Question 10

Fluid is distributed throughout the transmission to control shifts and provide lubrication to critical parts.

Accepted Answer

Fluid is an integral part of a transmission's operation, providing lubrication for moving parts and controlling gear shifts.

Question 11

Which of the following is LEAST-Likely a type of pump?

Accepted Answer

Inlet type is not a common type of pump. The other options are all common types of pumps used in various applications.

Question 12

All of the following statements are true EXCEPT:

Accepted Answer

The transmission shaft does not provide hydraulic fluid; instead, the transmission pump supplies hydraulic fluid to the torque converter, valve body, and lubrication circuits.

Question 13

While having a discussion about the Ravigneaux gearset, Technician A says that in overdrive, the direct clutch drives the planetary carrier clockwise, causing the long pinions to walk clockwise around the held large sun gear. Technician B says that this occurs in third gear. Who is correct?

Accepted Answer

Technician A is correct that in overdrive, the direct clutch drives the planetary carrier clockwise, causing the long pinions to walk clockwise around the held large sun gear. Technician B is incorrect in stating that this occurs in third gear, as the Ravigneaux gearset is a planetary gearset used in automatic transmissions that generally have multiple speeds.

Question 14

The term MOST-Likely used to describe a sensor that frequently sends an output voltage to the computer that varies with road speed is:

Accepted Answer

A sensor that frequently sends output voltage that varies with road speed is most likely the vehicle speed sensor.

Question 15

____________________ occurs when the vehicle is prevented from moving while the engine is accelerated.

Accepted Answer

The answer of ____________________ occurs when the vehicle is prevented...

Question 16

All of the following statements are true EXCEPT:

Accepted Answer

An overdrive cancel switch does not prevent shifting into gear, but rather allows the driver to manually prevent the transmission from shifting into overdrive.

Question 17

A ____ gearset uses two sun gears, two sets of planetary pinions connected to a single carrier, and a ring gear.

Accepted Answer

The description given matches that of a Ravigneaux gearset, which uses two sun gears and two sets of planetary pinions connected to a single carrier, along with a ring gear.

Question 18

The ____________________ is a lever that locks the transmission output shaft when the shift lever is in park.

Accepted Answer

The answer of The ____________________ is a lever that locks...

Question 19

With a standard torque converter, true coupling speed only happens when the vehicle crests a hill, when the engine stops driving the wheels and the wheels start to drive the engine.

Accepted Answer

A standard torque converter does not have a true coupling speed.

Question 20

The term MOST-Likely used to describe the readout on the instrument panel or steering column that tells the driver which gear range has been selected is:

Accepted Answer

The term commonly used to describe the readout on the instrument panel or steering column that tells the driver which gear range has been selected is the shift quadrant. This is a portion of the instrument panel that contains the indicators for the different gear ranges, such as P (Park), R (Reverse), N (Neutral), D (Drive), and so on. The driver can easily see which gear range has been selected based on the location of the indicator in the quadrant. The other choices, orifice, vortex, and detent are not related to the instrument panel or gear range selection.
