Answers (Verified Answers) Plus Rationales
2026 Q&A | Instant Download Pdf
1. What is the primary purpose of a torque converter in an automatic
transmission?
A. To provide a mechanical connection between engine and
transmission
B. To amplify engine torque and allow slip between engine and
transmission
C. To regulate transmission fluid pressure
D. To engage the parking pawl
B. 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.
,2. What type of transmission fluid is commonly used in most modern
automatic transmissions?
A. SAE 10W-30 motor oil
B. Automatic transmission fluid (ATF)
C. Gear oil
D. Brake fluid
B. Automatic transmission fluid (ATF)
Rationale: ATF provides lubrication, cooling, and hydraulic pressure
needed for proper transmission operation.
3. Which component in an automatic transmission controls the
engagement of clutches and bands?
A. Torque converter
B. Valve body
C. Planetary gear set
D. Transmission filter
B. Valve body
Rationale: The valve body directs hydraulic pressure to the
appropriate clutch or band to control gear selection.
4. What is the function of a planetary gear set in an automatic
transmission?
A. Filter transmission fluid
B. Provide different gear ratios
C. Increase engine horsepower
, D. Pump transmission fluid
B. Provide different gear ratios
Rationale: Planetary gear sets are responsible for producing the
various forward and reverse gear ratios in an automatic
transmission.
5. A vehicle with harsh or delayed shifts may have which of the following
issues?
A. Low engine oil
B. Worn transmission bands or clutches
C. Faulty spark plugs
D. Weak brake pads
B. Worn transmission bands or clutches
Rationale: Worn bands or clutches prevent proper engagement of
gears, leading to harsh or delayed shifting.
6. Which component is used to prevent the vehicle from rolling when in
the “Park” position?
A. Parking pawl
B. Output shaft
C. Torque converter stator
D. Planetary carrier
A. Parking pawl
Rationale: The parking pawl locks the transmission output shaft to
prevent vehicle movement when parked.
, 7. A transmission fluid cooler is used primarily to:
A. Increase transmission fluid pressure
B. Reduce fluid temperature and prevent overheating
C. Lubricate the engine
D. Increase fuel economy
B. Reduce fluid temperature and prevent overheating
Rationale: Cooling ATF helps maintain proper viscosity and prevents
damage to transmission components.
8. Which of the following is a common symptom of low ATF level?
A. Engine misfire
B. Slipping gears
C. Steering wheel vibration
D. Brake drag
B. Slipping gears
Rationale: Insufficient fluid reduces hydraulic pressure, causing
clutches and bands to slip.
9. What type of clutch is typically used in an automatic transmission to
engage specific gear sets?
A. Multiplate clutch
B. Dry friction clutch
C. Centrifugal clutch
D. Electromagnetic clutch
A. Multiplate clutch
