ASE A2 Automatic Transmission Practice Test

Clutch and band application chart.

46. An automatic transmission is slipping in second gear and has no overdrive. View the chart above to determine which of the following would MOST likely result in this condition?

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

46.

Answer A is wrong. Application charts are used to quickly pinpoint an automatic transmission area that's causing a shifting problem.

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

Answer C is correct. A worn 2-4 band would result in a slip in second and fourth 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 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. An automatic transmission with a planetary gearset is being diagnosed for harsh shifting. Which of these could be the cause?

  • 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.

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 leaking from the dipstick tube. Technician A says this could be caused by overfilling the transmission. Technician B says this leak could be 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 petroleum-based ATF is dyed red and turns dark brown when overheated. Technician B says a slipping band or clutch can cause burnt dark-colored transmission fluid. Who is correct?

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

50.

Answer A is wrong. Both technicians are correct. Transmission fluid is dyed red and turns dark-colored from heat and wear.

Answer B is wrong. Transmission fluid is susceptible to heat and can lose 50% of its effectiveness with an increase of 20° F.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.
