Exam 7: Transmission Components

Technician A says that transmissions with an input shaft speed sensor and a Vehicle Speed Sensor (VSS) can use this information to determine shift solenoid failure. Technician B says the input shaft speed sensor may also be called a turbine speed sensor. Who is correct?

Technician A says that the starter ring gear is always welded to the flex plate. Technician B says that some ring gears are welded to the outside of the torque converter case. Who is correct?

Which of the following parts make up a simple servo?

Technician A says transmission lip seals are made from neoprene. Technician B says transmission O-rings are made from neoprene rubber. Who is correct?

Technician A says bands are applied by applying fluid pressure to a servo. Technician B says a servo piston is typically sealed with a square-cut seal. Who is correct?

Which of the following can be described as a piston inside a bore which applies a brake band?

Which of the following are two other names commonly used for the manual lever position (MLP) switch?

Technician A says an average servo piston is approximately 2" in diameter. Technician B says some transmissions use a dual servo piston to apply a band. Who is correct?

Which of the following are a friction type of bearing similar to engine main bearings.

On newer vehicles, the band and servo linkage are adjustable as a maintenance item, and adjustment is required when the transmission fluid is serviced.

In the operation of a servo, fluid under pressure is directed onto one side of the piston in the closed cylinder, moving it to apply the band.

Which of the following seal designs are made from neoprene rubber and are often found sealing stationary parts of the transmission, such as a speedometer cable assembly or governor cover.

Which of the following sensors is a variable resistor called a potentiometer?

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

Technician A says most automatic transmissions use bushings around spinning components, rather than a roller bearing. Technician B front pump and extension housing bushings should always be replaced during a rebuild, but other bushings may be re-used if they are in good condition. Who is correct?

Which of the following components are found in the valve body?

When a gear is selected in a conventional automatic transmission, how is the input shaft torque delivered to the turning members of the planetary gear sets?

Technician A says that a torque converter is located between the engine and the transmission. Technician B says that a torque converter performs a similar function as a clutch in a manual transmission. Who is correct?

Which of the following input shaft speed sensor designs does not require a reference voltage to operate?

A torque converter dampens engine pulses, similar to a flywheel.
