Question 1

The input shaft is driven by the __________ inside of the torque converter.

Accepted Answer

The turbine inside the torque converter is connected to the input shaft, transferring power from the engine to the transmission.

Question 2

The input shaft is splined to lock into the front pump.

Accepted Answer

The answer of The input shaft is splined to lock...

Question 3

The __________ is the component that will deliver the torque from the transmission to either the driveshaft or the axle shafts.

Accepted Answer

The output shaft is responsible for delivering torque from the transmission to the driveshaft or axle shafts.

Question 4

On most vehicles, the stator support is built into the front pump.

Accepted Answer

The stator support is typically integrated into the front pump assembly in automatic transmissions, providing a stable mount for the stator.

Question 5

Technician A says that the stator support fits directly into the torque converter. Technician B says that while the stator support is located in the front pump housing, it does not turn inside the front pump. Who is correct?

Accepted Answer

The answer of Technician A says that the stator support...

Question 6

The parking pawl is attached to which component?

Accepted Answer

The parking pawl is a component in an automatic transmission that engages with the output shaft to lock the transmission and prevent the vehicle from moving when it is in the "Park" position.

Question 7

The differential is located in the transmission assembly on transaxles, which are used mostly on rear wheel drive vehicles.

Accepted Answer

Transaxles are typically used in front-wheel-drive vehicles, where the differential is integrated with the transmission. Rear-wheel-drive vehicles usually have a separate differential located in the rear axle.

Question 8

Technician A says that a differential allows power to be sent unequally to one drive axle. Technician B says that the differential uses a series of gears to transfer power to the wheel with the most traction. Who is correct?

Accepted Answer

A differential allows power to be sent unequally to the wheels, not the drive axle, and it transfers power to the wheel with the least traction, not the most.

Question 9

The differential in a transmission transaxle allows the power to be split between the two front wheels.

Accepted Answer

The differential in a transaxle allows for the distribution of engine power to the front wheels, enabling them to rotate at different speeds, which is essential for smooth turning.

Question 10

On an RWD vehicle, the output shaft will have long splines to allow the driveshaft to slide in and out of the rear of the transmission.

Accepted Answer

The long splines on the output shaft of an RWD vehicle's transmission allow for the driveshaft to accommodate changes in length as the suspension moves, ensuring smooth power delivery.

Question 11

In a computerized transmission, which of the component below replaces the governor?

Accepted Answer

The answer of In a computerized transmission, which of the...

Question 12

Which sensor do some manufacturers compare to the input shaft speed sensor to measure the amount of time required to complete the shift from one gear to another?

Accepted Answer

The output shaft speed sensor is compared to the input shaft speed sensor to determine the time required to complete a gear shift, as it provides information on the speed of the transmission's output shaft.

Question 13

What type of variable resistor used in a Throttle Position Sensor (TPS)?

Accepted Answer

A Throttle Position Sensor (TPS) typically uses a potentiometer to measure the position of the throttle valve.

Question 14

Which of the following sensors is a potentiometer design?

Accepted Answer

A throttle position sensor is often designed as a potentiometer, which measures the position of the throttle valve.

Question 15

Which of the following sensors measures the actual amount of air coming into the engine, so the Powertrain Control Module (PCM) can accurately inject the proper amount of fuel.

Accepted Answer

The Mass Air Flow (MAF) sensor measures the actual amount of air entering the engine, allowing the PCM to adjust the fuel injection accordingly.

Question 16

Which of the following sensor designs can be used as Crankshaft Position Sensors (CKP)?

Accepted Answer

All the listed sensor designs—magnetic pickup, Hall-Effect, and optical-style sensors—can be used as crankshaft position sensors, as they are capable of detecting the position and rotational speed of the crankshaft.

Question 17

Which of the following sensors can the Powertrain Control Module (PCM) use to determine engine speed?

Accepted Answer

The Crankshaft Position (CKP) sensor is used by the PCM to determine engine speed by monitoring the position and rotational speed of the crankshaft.

Question 18

When the Powertrain Control Module compares the Crankshaft Position Sensor (CKP) sensor signal to the Input Shaft Speed (ISS) sensor in the transmission, what does the difference between these two sensors indicate?

Accepted Answer

The answer of When the Powertrain Control Module compares the...

Question 19

Which of the following sensors does the Powertrain Control Module (PCM) compare to the input shaft speed sensor to determine the amount of torque converter slippage and to control the lockup of the Torque Converter Clutch (TCC).

Accepted Answer

The CKP sensor provides the PCM with the engine speed, which is used to compare to the input shaft speed sensor to determine the amount of torque converter slippage.

Question 20

The PCM monitors the TPS sensor along with the VSS to determine a driver's ________.

Accepted Answer

The PCM (Powertrain Control Module) uses the Throttle Position Sensor (TPS) and Vehicle Speed Sensor (VSS) to monitor and analyze a driver's driving pattern, such as acceleration and deceleration habits.
