ASE A2 Automatic Transmission Practice Test

16. Two technicians are removing a transmission's valve body. Technician A says the separator plate blocks off some passages while allowing fluid to flow in others. Technician B says the seat for a ball-type check valve may be located in the separator plate. Who is correct?

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

16.

Answer A is wrong. A separator plate blocks some channels while allowing flow in others.

Answer B is wrong. The separator plate has orifices that serve as a seat for ball type check valves.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

17. A vehicle lacks power when accelerating from a stop. Technician A says this could be caused by chipped teeth on the pinion gears. Technician B says the torque converter's one-way stator clutch may be slipping. Who is correct?

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

17.

Answer A is wrong. Chipped gear teeth are likely to make noise and possibly a vibration.

Answer B is correct. If the stator one-way clutch does not lock, the vehicle will suffer from a sluggish start.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

18. Which member of the planetary gear set has internal teeth?

  • A. The sun gear.
  • B. The ring gear.
  • C. The pinion gear.
  • D. The spur gear.

18.

Answer A is wrong. The sun gear uses external teeth in mesh with the pinion gears.

Answer B is correct. The ring or annulas gear has internal teeth and is in mesh with the pinion gears.

Answer C is wrong. The pinion gear set has external teeth in mesh with both the sun and pinion gears.

Answer D is wrong. A spur gear is a straight (not helical) gear used in older manual transmissions.

19. Two technicians are discussing a vehicle's torque converter. Technician A says if the torque converter's hub has any imperfections it should be replaced. Technician B says the depth of the torque converter into the case should be measured before removal. Who is correct?

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

19.

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

Answer B is correct. The depth of the converter into the case assures proper engagement of the transmission pump to the torque converter hub.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

20. Technician A says the MAP sensor is for the engine and has no affect on transmission shift control. Technician B says the MAF sensor provides information about engine load to the TCM (transmission control module) and is important for TCM shift control. Who is correct?

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

20.

Answer A is wrong. The transmission control module uses inputs from the ECT, MAF, MAP, VSS, TPI etc.

Answer B is correct. The MAF (mass air flow) sensor provides information about engine load to the TCM (transmission control module) and is important for shift control.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
