Exam 7: Transmission Components

Which of the following is most likely to be used with an automatic transmission?

Tech A states that transaxles will have a differential assembly built into the transmission to allow the output shafts to spin at different speeds. Tech B states that transaxles will have a final drive gear set built into the transmission. Who is correct?

Which of the following is the type of sensor used to measure transmission line pressure?

Choose the statement that correctly describes the function of a front hydraulic pump.

When a servo applies pressure to one end of the band, how does it hold the planetary member?

Technician A says a servo-operated band can only hold a member stationary in an automatic transmission. Technician B says multi-disc clutches can hold or drive individual members of the planetary set in an automatic transmission. Who is correct?

Which of the following seal designs have tapered ends that overlap when the seal is wrapped around the shaft it is sealing?

Technician A says that when rebuilding an automatic transmission, the valve body requires no special service. Technician B says that when rebuilding an automatic transmission, the valve body never needs to be replaced. Who is correct?

When the driver shifts the transmission into park, a lever, called a parking pawl, is forced into notches cut into a hardened steel drum on the output shaft of the transmission.

Technician A says that a valve body on some RWD vehicles can be serviced by removing the side pan. Technician B says that the valve body on some FWD vehicles can be serviced by removing the lower pan. Who is correct?

Fluid can be trapped at the outer portion of the clutch cylinder due to centrifugal force. What prevents this from happening?

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

Technician A says the majority of automatic transmission control valves are located inside the valve body. Technician B says a typical valve body is made of aluminum or cast iron. Who is correct?

Technician A says the parking pawl prevents the transmission's input shaft from rotating. Technician B says the vehicle may have to roll an inch or two for the parking pawl to engage. Who is correct?

The front pump bushing should be replaced in all of the following instances except:

Technician A says that a lock up converter is used to achieve a 1:1 speed ratio between the engine and the transmission input shaft. Technician B says that lock up only occurs at higher road speeds. Who is correct?

A line pressure sensor is a transducer that varies resistance with the pressure applied to the sensor element.

If the linkage is too short when the servo applies, the band may slip when applied.

Technician A says there are many types of internal seals for an automatic transmission. Technician B says a square-cut seal can be made from cork or rubber. Who is correct?

What kind of variable resistor is a transmission oil temperature (TOT) sensor?
