ASE Practice Test (A2: Automatic Transmission/Transaxle)

Question 1

A vehicle with an automatic transmission slips in all forward gears but operates normally in reverse. The MOST likely cause is:

Accepted Answer

A worn or slipping forward clutch pack

Answer

A faulty torque converter clutch solenoid

Answer

Low line pressure in the reverse circuit only

Answer

A stuck open pressure regulator valve

Question 2

During a stall speed test, the stall speed is 300 RPM HIGHER than the manufacturer's specification. This indicates:

Accepted Answer

Torque converter stator clutch is slipping

Answer

Engine is producing too much power

Answer

Transmission clutches and bands are holding properly

Answer

Torque converter is functioning correctly

Question 3

A technician is checking line pressure on an automatic transmission. Line pressure is low in all ranges. The MOST likely cause is:

Accepted Answer

A faulty pressure regulator valve or worn pump

Answer

A clogged transmission filter

Answer

A stuck shift solenoid

Answer

An open circuit in the TPS sensor

Question 4

A vehicle with an electronically controlled automatic transmission has a harsh 1-2 shift. Technician A says the 1-2 shift solenoid may be faulty. Technician B says the 1-2 accumulator may be weak or damaged. Who is correct?

Accepted Answer

Both Technician A and Technician B

Answer

Technician A only

Answer

Technician B only

Answer

Neither Technician A nor Technician B

Question 5

When performing a transmission fluid condition check, the fluid appears dark brown and has a burned odor. This indicates:

Accepted Answer

Overheating causing clutch material contamination

Answer

Normal ATF oxidation from high mileage use

Answer

The fluid was recently changed with incorrect viscosity

Answer

Water contamination from a failed cooler

Question 6

A torque converter is being inspected after removal. The converter pilot is damaged and out of round. This will MOST likely cause:

Accepted Answer

Vibration and noise during torque converter operation

Answer

Transmission slipping in all forward gears

Answer

Harsh engagement when shifting into reverse

Answer

Converter shudder only during light throttle acceleration
