Exam 7: Transmission Components

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?

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

Which of the following is typically the output of a reed switch?

Which of the following is found in a valve body?

Technician A says that a manual transmission utilizes a flywheel and an automatic transmission utilizes a flexplate. Technician B says that a flexplate can be lighter than a flywheel. Who is correct?

Which of the following is least likely to be used as a servo piston seal?

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

What kind of pump uses a spring-loaded movable pump housing that pivots in such a way that the volume of the pumping chambers can be increased or decreased based on fluid pressure.

Which of the following is found in a valve body?

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 a variable displacement vane pump reduces the pumping load on the engine when the transmission requires less fluid to be pumped. Technician B says the gear type pump can also be variable displacement. Who is correct?

Technician A says that the Powertrain Control Module (PCM) or Transmission Control Module (TCM) varies shift timing and pressure based upon the transmission fluid temperature (TFT) sensor readings. Technician B says that TOT readings can typically be viewed using a scan tool. Who is correct?

The line pressure sensor in an automatic transmission is supplied with reference voltage from the PCM.

A band has a _______ layer of friction material bonded onto spring steel or cast steel backing.

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

The Powertrain Control Module (PCM) or Transmission Control Module (TCM) varies shift timing and pressure based upon the Transmission Fluid Temperature (TFT) sensor readings.

Technician A says a variable displacement vane pump reduces the pumping load on the engine when the transmission requires less fluid to be pumped. Technician B says the flexplate is bolted to the input shaft of the transmission. Who is correct?

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?

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?

Which valve modulates pressure in proportion with vehicle speed?
