1. What is the primary function of an automatic transmission torque
converter?
A. Increase engine horsepower
B. Transfer and multiply engine torque to the transmission
C. Reduce fuel consumption
D. Control gear shifting electronically
Answer: B
Rationale: The torque converter transfers engine power to the
transmission and provides torque multiplication at low speeds.
2. Which component locks the torque converter to eliminate slippage at
cruising speed?
A. Stator
B. Impeller
C. Lock-up clutch
D. Turbine
Answer: C
, Rationale: The lock-up clutch engages to create a direct connection,
improving efficiency.
3. What does a slipping transmission typically indicate?
A. Low tire pressure
B. Worn clutches or bands
C. Faulty spark plugs
D. Overfilled coolant
Answer: B
Rationale: Slipping occurs when clutches or bands cannot hold properly
due to wear or low pressure.
4. Which fluid is commonly used in automatic transmissions?
A. Brake fluid
B. Engine oil
C. Automatic Transmission Fluid (ATF)
D. Power steering fluid
Answer: C
Rationale: ATF provides lubrication, cooling, and hydraulic pressure.
5. What is the purpose of the valve body?
A. Store transmission fluid
B. Control hydraulic circuits and gear shifts
C. Support engine mounts
D. Reduce emissions
Answer: B
Rationale: The valve body directs fluid to control gear changes.
6. A delayed engagement when shifting into drive is often caused by:
A. High fluid level
B. Low fluid level or worn seals
C. New transmission fluid
D. Proper line pressure
Answer: B
Rationale: Low fluid or leaking seals reduce hydraulic pressure.
, 7. What does the stator do in a torque converter?
A. Transfers power to wheels
B. Redirects fluid to increase torque
C. Controls gear ratios
D. Filters transmission fluid
Answer: B
Rationale: The stator redirects returning fluid to improve torque
multiplication.
8. Which gear set is commonly used in automatic transmissions?
A. Spur gear
B. Helical gear
C. Planetary gear set
D. Bevel gear
Answer: C
Rationale: Planetary gear sets allow multiple gear ratios in a compact
design.
9. What happens if ATF is contaminated?
A. Increased efficiency
B. Reduced wear
C. Poor shifting and damage
D. Improved cooling
Answer: C
Rationale: Contaminated fluid leads to improper lubrication and hydraulic
issues.
10.Which component applies pressure to engage clutches?
A. Pump
B. Solenoid
C. Hydraulic pistons
D. Filter
Answer: C
Rationale: Pistons use hydraulic pressure to apply clutches.
