ASE A2 Automatic Transmission Practice Test

11. Technician A says a transmission brake band is a holding device. Technician B says a hydraulically controlled servo is used to activate the brake band. Who is correct?

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

11.

Answer A is wrong. A brake band stops and holds the drum that is connected to a member of the planetary gear set.

Answer B is wrong. The servo assembly applies pressure to the band which in turn holds the drum.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

12. Automatic Transmissions use all of these pressures for shift control EXCEPT:

  • A. Governor
  • B. Torque Converter
  • C. Vacuum Modulator
  • D. Throttle Valve

12.

Answer A is wrong. The governor is a pressure control device.

Answer B is correct. A torque converter is a fluid coupling between the engine and the transmission.

Answer C is wrong. A vacuum modulator is a pressure control device.

Answer D is wrong. A throttle valve is a pressure control device.

13. All of these are types of transmission oil pumps EXCEPT.

  • A. Rotor
  • B. Vane
  • C. Diaphragm
  • D. Gear

13.

Answer A is wrong. Automatic transmissions use rotor-type pumps.

Answer B is wrong. Automatic transmissions use vane-type pumps

Answer C is correct. Automatic transmissions do not use diaphragm pumps.

Answer D is wrong. Automatic transmissions use gear-type pumps.

14. An automatic transmission has delayed initial engagement when shifted into drive and reverse. Technician A says a clogged transmission oil filter will result in this condition. Technician B says oil pump starvation causes delayed shift engagement. Who is correct?

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

14.

Answer A is wrong. Both technicians are correct. A clogged oil filter results in oil pump starvation; the blockage obstructs the oil pumps fluid supply.

Answer B is wrong. Both technicians are correct. It causes low line pressure. Filter kits are available to replace the old filter and gasket as a regular maintenance procedure.

Answer C is correct. This condition starves the oil pump of necessary fluid flow resulting in low line pressure. It also results in damaging clutch and band slippage.

Answer D is wrong. Both technicians are correct.

15. Technician A says a TR sensor (Transmission Range Sensor) can be tested using an ohmmeter. Technician B says an improperly adjusted neutral safety switch can prevent a vehicle from starting. Who is correct?

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

15.

Answer A is wrong. Both Technicians are correct. An ohmmeter can be used to diagnose an analog TR Sensor.

Answer B is wrong. A faulty neutral safety switch can prevent a vehicle from starting.

Answer C is correct. Both Technicians are correct. An ohmmeter can be used to diagnose an analog TR Sensor. A neutral safety switch can prevent a vehicle from starting.

Answer D is wrong. A neutral safety switch can prevent a vehicle from starting. An ohmmeter can be used to diagnose an analog TR Sensor.
