1. What is the primary function of a torque converter in an automatic transmission?
Engages and disengages gears
Transfers rotating power from the engine to the transmission.
Filters transmission fluid
Regulates hydraulic pressure
2. What is a common symptom of a faulty solenoid in an automatic transmission?
Engine overheating
Erratic shifting or failure to shift
Brake failure
Excessive vibration
3. Why is it important to maintain the correct level of transmission fluid?
It supports proper fuel combustion
It ensures proper lubrication and cooling of transmission components.
It prevents rust on the vehicle's body
It maintains battery charge
4. In an automatic transmission, what does the valve body control?
The operation of the brake system
The flow of hydraulic fluid to various parts of the transmission.
The timing of engine spark plugs
The air-fuel mixture in the combustion chamber
5. What is the probable cause of a burning smell coming from an automatic transmission?
Worn spark plugs
Closed air vents
Faulty brake pads
Overheated transmission fluid
6. Which component in an automatic transmission is primarily responsible for the gear ratio changes?
Planetary gear set
Torque converter
Solenoid valve
Hydraulic pump
7. What common issue may indicate a problem with the transmission filter?
Steering wheel vibration
Dirty or clogged filter leading to sluggish performance
Faulty headlight dimming
Reduced engine power
8. Why is properly maintaining transmission fluid pressure important?
It keeps the tires inflated
It ensures the proper engagement of clutches and bands.
It powers the vehicle’s air conditioning system
It maintains engine coolant temperature
9. What is a common method for diagnosing issues in modern automatic transmissions?
OBD-II scanning
Checking the radiator level
Testing the battery voltage
Inspecting the tailpipe
10. What is a sign that your vehicle’s transmission might be slipping?
Headlights dim when braking
Engine RPMs increase without a corresponding increase in speed
Consistent fuel economy
Steering wheel shakes
11. How often should the transmission fluid be replaced to ensure optimal transmission health?
Every 30,000 to 60,000 miles
Every 5,000 miles
Only when it turns brown
Never, it should last the life of the vehicle
12. What is the purpose of a transmission cooler?
To lower the temperature of the transmission fluid
