ASE A2 Automatic Transmission Practice Test

1. After a long drive, red fluid is seen on the transmission case and under the chassis of a vehicle. Technician A says this could be caused by fluid aeration. Technician B says this could be caused by engine overheating. Who is correct?

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

1.

Answer A is wrong. Low or high fluid levels result in aeration. Overfilling or overheating a transmission results in fluid flowing from the vent or fill tube.

Answer B is wrong. Transmission fluid is cooled in the cooler located in the coolest radiator well of the engine's cooling system.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

2. There are metal flakes and shavings at the bottom of a transmission's oil pan. Which of the following is causing this debris?

  • A. This is normal.
  • B. A worn band.
  • C. A worn clutch.
  • D. Chipped gear teeth.

2.

Answer A is wrong. This is not a normal condition.

Answer B is wrong. It is normal to find fine particles, especially around the magnet.

Answer C is wrong. Black pieces found in the bottom of the pan indicate worn clutch and band friction material.

Answer D is correct. Metal flakes and shavings found in the bottom of the oil pan indicate chipped or worn gearset teeth.

3. A vehicle with an automatic transmission creeps forward in neutral. Which of the following is MOST likely causing this condition?

  • A. The pressure regulator valve.
  • B. The manual valve.
  • C. A shift valve.
  • D. The throttle valve.

3.

Answer A is wrong. The pressure regulator valve controls mainline pressure.

Answer B is correct. A worn or misadjusted manual valve can lead to pressure bleed between hydraulic circuits.

Answer C is wrong. Shift valves control the reactionary devices (clutches and bands).

Answer D is wrong. Answer B is correct.

4. When removing a torque converter from an automatic transmission, the technician should:

  • A. Measure the depth of the torque converter into the transmission's bell housing before removal.
  • B. Inspect the torque converter's hub for discoloring, nicks, scratches, and burrs.
  • C. Both A and B.
  • D. Neither A or B.
Measure the depth of the torque converter into the transmission’s bell housing

4.

Answer A is wrong. Measure the depth of the torque converter into the transmission's bell housing to ensure that the converter is correctly aligned with the transmission oil pump when reinstalling.

Answer B is wrong. Small nicks, scratches, and burrs can be removed from the hub using fine crocus cloth.

Answer C is correct. Both answers are correct.

Answer D is wrong. Both answers are correct.

5. A vehicle's automatic transmission is not downshifting correctly. A vacuum hose is detached and hanging down by the transmission pan. This vacuum hose should be connected to which of the following?

  • A. The Governor.
  • B. The Throttle Position Sensor.
  • C. The Modulator.
  • D. The Vehicle Speed Sensor.

5.

Answer A is wrong. Governors are used in hydraulically controlled transmissions to indicate vehicle speed.

Answer B is wrong. A throttle position sensor is used in today's electronically controlled transmissions to indicate load. They replace the modulators used in older transmissions.

Answer C is correct. A modulator is a vacuum controlled device that controls throttle pressure.

Answer D is wrong. Vehicle speed sensors replace the governor in older hydraulic transmissions.
