ASE A2 Automatic Transmission Practice Test

Gear ratio chart

41. Refer to the chart above. Which gear ratio best represents overdrive?

  • A. 4.027:1
  • B. 0.852:1
  • C. 3.064:1
  • D. None of these.

41.

Answer A is wrong. This ratio (4.027:1) represents gear reduction.

Answer B is correct. This ratio (0.852:1) represents overdrive.

Answer C is wrong. This ratio (3.064:1) represents gear reduction.

Answer D is wrong. Answer B (0.852:1) represents overdrive.

42. An excessive clunk is felt while placing an automatic transaxle into gear. Technician A says this could be excessive deflection in the final drive chain. Technician B says this could be worn universal joints. Who is correct?

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

42.

Answer A is correct. Chain deflection is checked by moving the chain in and marking the case, then moving the chain out and marking it again. The sum of the two equals total deflection. There is usually little deflection in a Transaxle/Final Drive chain.

Answer B is wrong. Transaxle's use axles or shafts with CV joints. Rear wheel drive vehicle's use driveshafts with universal joints.

Answer C is wrong. Answer A is correct.

Answer D is wrong. Answer A is correct.

43. An automatic transaxle loses pressure as it shifts from first to second gear. Technician A says this could be caused by the clutch piston seal. Technician B says this could be caused by a stuck servo. Who is correct?

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

43.

Answer A is correct. A leaking clutch piston seal will cause a drop in pressure.

Answer B is wrong. A stuck servo would not create a drop in pressure.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

44. An automatic transmission has a late delayed shift from first to second gear. All other shift points are normal. The 1-2 shift valve is suspected of sticking in its bore. Technician A says to clean the transmission valves and valve body to remove tarnish and dry them with compressed air before placing them back into service. Technician B says a slightly bent spool valve can be repaired and placed back into service. Who is correct?

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

44.

Answer A is correct. Clean the valves with a varnish removing or a carburetor type cleaner and carefully dry them with compressed air.

Answer B is wrong. Bent transmission valves should be replaced not repaired.

Answer C is wrong. Tarnish forms from heat and oxidation. This problem is often caused by neglect. It coats the inside of the transmission with a brown colored goo. This condition is easily detected on the transmission dipstick. It's important to monitor and change the transmission fluid at regular intervals.

Answer D is wrong. Technician A is correct.

45. 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

45.

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.
