ASE A2 Automatic Transmission/Transaxle Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of a torque converter in an automatic

transmission?

• To provide a mechanical connection between engine and

transmission

• To amplify engine torque and allow slip between engine and

transmission

• To regulate transmission fluid pressure
• To engage the parking pawl
• To amplify engine torque and allow slip between engine and

transmission

Rationale: The torque converter transmits engine power to the

transmission while allowing the engine to continue running when the vehicle is stopped. 1 / 4

• What type of transmission fluid is commonly used in most modern

automatic transmissions?

• SAE 10W-30 motor oil
• Automatic transmission fluid (ATF)
• Gear oil
• Brake fluid
• Automatic transmission fluid (ATF)

Rationale: ATF provides lubrication, cooling, and hydraulic pressure

needed for proper transmission operation.

• Which component in an automatic transmission controls the

engagement of clutches and bands?

• Torque converter
• Valve body
• Planetary gear set
• Transmission filter
• Valve body

Rationale: The valve body directs hydraulic pressure to the

appropriate clutch or band to control gear selection.

• What is the function of a planetary gear set in an automatic

transmission?

• Filter transmission fluid
• Provide different gear ratios
• Increase engine horsepower 2 / 4

• Pump transmission fluid
• Provide different gear ratios

Rationale: Planetary gear sets are responsible for producing the

various forward and reverse gear ratios in an automatic transmission.

• A vehicle with harsh or delayed shifts may have which of the following

issues?

• Low engine oil
• Worn transmission bands or clutches
• Faulty spark plugs
• Weak brake pads
• Worn transmission bands or clutches

Rationale: Worn bands or clutches prevent proper engagement of

gears, leading to harsh or delayed shifting.

• Which component is used to prevent the vehicle from rolling when in

the “Park” position?

• Parking pawl
• Output shaft
• Torque converter stator
• Planetary carrier
• Parking pawl

Rationale: The parking pawl locks the transmission output shaft to

prevent vehicle movement when parked. 3 / 4

7. A transmission fluid cooler is used primarily to:

• Increase transmission fluid pressure
• Reduce fluid temperature and prevent overheating
• Lubricate the engine
• Increase fuel economy
• Reduce fluid temperature and prevent overheating

Rationale: Cooling ATF helps maintain proper viscosity and prevents

damage to transmission components.

• Which of the following is a common symptom of low ATF level?
• Engine misfire
• Slipping gears
• Steering wheel vibration
• Brake drag
• Slipping gears

Rationale: Insufficient fluid reduces hydraulic pressure, causing

clutches and bands to slip.

• What type of clutch is typically used in an automatic transmission to

engage specific gear sets?

• Multiplate clutch
• Dry friction clutch
• Centrifugal clutch
• Electromagnetic clutch
• Multiplate clutch
