ASE A2 Automatic Transmission Practice Test

Clutch and band application chart.

6. An automatic transmission has no overdrive and slips in second gear. 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.

6.

Answer A is wrong. Application charts quickly pinpoint an automatic transmission area causing a shifting problem.

Answer B is wrong. Through elimination, this handy chart can help determine the faulty component.

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.

7. A torque converter's stator:

  • A. Should spin freely in both directions.
  • B. Spins freely until the torque converter reaches its coupling phase.
  • C. Is fastened to the impeller.
  • D. Has a one-way clutch that allows the stator to spin freely in one direction but keeps it from rotating in the other.

7.

Answer A is wrong. If the stator is locked or spins freely in both directions, it needs replacement.

Answer B is wrong. If the stator's one-way clutch spins freely at low speeds, there will be a loss of torque multiplication, resulting in poor low-speed performance.

Answer C is wrong. It is not fastened to the impeller.

Answer D is correct. A stator has a one-way clutch that allows it to spin freely in one direction but keeps it from rotating in the other.

8. 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.

8.

Answer A is wrong. The regulator regulates and exhausts excessive pressure in the transmission 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.

9. 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

9.

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.

10. 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

10.

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.
