ASE A2 Automatic Transmission Practice Test

Clutch and band application chart.

46. After verifying a complaint of a slipping second gear and no overdrive the technician refers to the chart above. Which of the following would result in this slipping transmission?

  • A. The forward clutch.
  • B. The low roller clutch.
  • C. The 2-4 band.
  • D. The low reverse clutch.

46.

Answer A is wrong. Application charts are used to quickly pin point the area of an automatic transmission that’s causing a shifting problem.

Answer B is wrong. Through a process of elimination the faulty component can be located using this handy tool.

Answer C is correct. A worn 2-4 band would result in a slip in second and forth gear.

Answer D is wrong. Answer C is correct.

Transmssion solenoid chart.

47. Transmission solenoid, clutch and band charts are diagnostic tools used to diagnose shifting problems. A vehicle is not shifting into first gear and has no overdrive. View the chart above to determine which of the following is MOST likely correct.

  • A. Shift solenoid A is faulty.
  • B. Shift solenoid A's circuit is compromised.
  • C. Shift solenoid B is faulty.
  • D. Both A and B are correct.

47.

Answer A is wrong. The solenoid or the circuit could be the problem.

Answer B is wrong. Both A and B are correct.

Answer C is wrong. The TCM powers solenoid B to shift into first and second gears.

Answer D is correct. Both A and B are correct.

48. A harsh shifting automatic transmission with a planetary gearset is being diagnosed. Which of the following would cause this hard shifting transmission?

  • A. A sticking pressure regulating valve.
  • B. A faulty EPC solenoid.
  • C. Old contaminated fluid.
  • D. All of the above.

48.

Answer A is wrong. The regulator regulates and exhausts excessive pressure to the sump preventing any damage to friction materials and internal components.

Answer B is wrong. If the vehicle’s line pressure is above or below specifications, the EPC solenoid and its circuit can be tested and diagnosed with a scanner and an ohmmeter.

Answer C is wrong. Contaminated fluid causes valves, like the pressure regulating valve, to stick in their bores.

Answer D is correct. All of the above answers are correct.

49. Transmission fluid is seen leaking from the dipstick tube. Technician A says is caused by overfilling the transmission. Technician B says this is caused by aerated and foamy fluid. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

49.

Answer A is wrong. Overfilling a transmission causes the fluid to become aerated and foamy.

Answer B is wrong. Overheated fluid appears dark brown or black.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

50. Technician A says that the vehicle speed sensor is driven by the input shaft of an automatic transmission. Technician B says that the parking pawl engages the input shaft to lock an automatic transmission in park. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

50.

Answer A is wrong. Neither Technician A or B were correct.

Answer B is wrong. Neither Technician A or B were correct.

Answer C is wrong. Neither Technician A or B were correct.

Answer D is correct. Both the parking pawl and the vehicle speed sensor are associated with the output shaft.
