ASE A2 Automatic Transmission Practice Test

36. After a long drive red fluid is seen on the transmission case and under chassis of a vehicle. Technician A says this can 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

36.

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.

37. The MIL is illuminated and the transmission only operates in third and reverse gears. Which of the following is the MOST likely cause of this condition?

  • A. Adaptive learning.
  • B. High line pressure.
  • C. Low line pressure.
  • D. Limp-in mode.

37.

Answer A is wrong. Today's electronic transmissions adapt and compensate for conditions such as clutch and band wear.

Answer B is wrong. High line pressure results in hard shifting

Answer C is wrong. Low line pressure results in slipping and excessive clutch and band wear.

Answer D is correct. This is the most likely choice. Inspect and test this vehicle to see if it's in limp-in mode.

38. Which of the following affect shift points in relation to vehicle speed?

  • A. The throttle valve.
  • B. The governor.
  • C. Both of these.
  • D. Neither of these.

38.

Answer A is wrong. Throttle pressure is related to vehicle load.

Answer B is correct. Governor pressure is related to vehicle speed.

Answer C is wrong. Answer B is correct.

Answer D is wrong. Answer B is correct.

39. While testing the TCM of an electronic automatic transmission the technician should use at least a:

  • A. 1 Megohm tester.
  • B. 5 Megohm tester.
  • C. 10 Megohm tester.
  • D. 20 Megohm tester.

39.

Answer A is wrong. Use a tester with at least 10 Megohms of resistance.

Answer B is wrong. Answer C is correct.

Answer C is correct. Using a tester with at least 10 Megohm of resistance protects sensitive circuits from overload.

Answer D is wrong. Answer C is correct.

40. A vehicle with an electronic automatic transmission is hunting for gears and having difficulty with shift timing. A scan indicates several sensors and shift solenoids are faulty. Technician A says to replace the sensors and rescan the TCM. Technician B says to inspect the circuits leading the these components. Who is correct?

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

40.

Answer A is wrong. Inspect related circuitry and wiring related to the component before replacing it.

Answer B is correct. Inspect the wiring, plugs and harness leading to the transmission case.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
