Exam 7: Transmission Components

Which of the following describes torque multiplication in a torque converter?

Tech A states that lip seals are commonly used in automatic transmissions. Tech B states that some seals require special tools to install. Who is correct?

Many of the valves inside the valve body are operated by hydraulic pressure and springs.

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?

Which of the following is another name for the input shaft speed sensor?

The parking pawl is attached to which component?

In an electronically controlled automatic transmission, which of the following sensors changes resistance based upon the regulated hydraulic pressure output from the front pump?

Technician A say that the valves found in the valve body are operated by hydraulic and spring pressure. Technician B says that if the valves do not move freely, the vehicle will not shift properly. Who is correct?

Which of the following materials are transmission pump housings made from?

Technician A says that multi-plate clutches must have a specified amount of clearance when they are installed. Technician B says that there should be no clearance when they are installed because the clutch would slip. Who is correct?

Which of the following two materials are most commonly used to make transmission pump housings?

The extension housing seal is considered an internal transmission seal.

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.

Some transmissions use variable displacement pumps to reduces the pumping load on the engine when the transmission requires less fluid to be pumped. Which of the following pump designs are used as variable displacement pumps?

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

Which of the following is used to connect the engine crankshaft to the torque converter?

Which of the following seal designs is typically used between the front pump and the rotating clutch drums.

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?

Technician A says that the valve body on a rear wheel drive vehicle may be found in the lower transmission pan. Technician B says that the valve body on a front wheel drive vehicle may be found behind the side transmission pan. Who is correct?

How many of each, friction plates and steel plates, are commonly used in a multi-disc clutch?
