ASE A2 Automatic Transmission Practice Test

Gear ratio chart

6. 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.

6.

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.

7. A final drive assembly has been replaced. Technician A says to use an inch pound torque wrench to check for proper pinion preload. Technician B says to use a dial indicator to check the ring gear’s backlash. Who is correct?

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

7.

Answer A is wrong. Both technicians are correct. Use an inch pound torque wrench to check for proper pinion preload.

Answer B is wrong. Helical gears are typical in final drive assemblies. The ring gear should be checked for backlash using a dial indicator.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Answer C is correct.

8. 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

8.

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.

9. 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

9.

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.

10. Technician A says to pressure test a transmission if an internal leak is suspected. Technician B says pressure testing ports are located on the transmission case. Who is correct?

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

10.

Answer A is wrong. Perform a pressure test to diagnose hard shifting and poor shift timing.

Answer B is wrong. The ports are located on the transmission case.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.
