- Q1What is a torque converter in an automatic transmission?A hydraulic coupling that transmits power from the engine to the transmissionA device that changes gears automaticallyA mechanism that regulates fluid pressure in the transmissionA component that controls the clutch engagement30s
- Q2What is a transmission fluid?A mechanism that regulates the speed of the vehicleA lubricant used to cool and lubricate the components of an automatic transmissionA component that converts mechanical energy into hydraulic pressureA device that controls the flow of power in an automatic transmission30s
- Q3What is a gear ratio in an automatic transmission?The speed at which the transmission shifts gearsThe measurement of the transmission fluid levelThe ratio between the number of teeth on two meshing gearsThe distance traveled by the vehicle per engine revolution30s
- Q4What is an overdrive gear in an automatic transmission?A gear that allows the engine to operate at a lower RPM for better fuel efficiency at higher speedsA gear that assists in hill climbing and towingA gear that engages when the vehicle is moving in reverseA gear that provides maximum acceleration and power30s
- Q5What is a shift solenoid in an automatic transmission?A sensor that measures the speed of the vehicleAn electronic valve that controls the flow of transmission fluid to engage specific gearsA mechanical linkage that connects the shifter to the transmissionA component that adjusts the throttle position30s
- Q6What is the purpose of a torque converter lock-up clutch in an automatic transmission?To facilitate smooth shifting between gearsTo provide maximum acceleration and power during high-speed drivingTo engage the reverse gear in the transmissionTo improve fuel efficiency and reduce heat generated by the torque converter30s
- Q7What is the purpose of the 'Park' gear in an automatic transmission?To disengage the transmissionTo engage engine brakingTo increase engine powerTo securely hold the vehicle in place30s
- Q8Which component in an automatic transmission is responsible for shifting gears?The engine control unitThe torque converterThe transmission control unitThe throttle body30s
- Q9What does the 'D' stand for in an automatic transmission?DriveDirectionDynamicDive30s
- Q10What is the purpose of the 'Overdrive' gear in an automatic transmission?To reduce engine speed and improve fuel efficiencyTo activate engine brakingTo increase engine power and speedTo disengage the transmission30s
- Q11Which gear in an automatic transmission allows the engine to run without transmitting power to the wheels?ReverseDriveParkNeutral30s
- Q12What is the purpose of the 'Reverse' gear in an automatic transmission?To move the vehicle backwardTo disengage the transmissionTo increase engine powerTo activate overdrive30s
- Q13Which pedal is used to control the speed of a vehicle equipped with an automatic transmission?The parking brake pedalThe accelerator pedalThe clutch pedalThe brake pedal30s
- Q14When should you use the 'Park' gear in an automatic transmission?When parking or leaving the vehicleWhen changing lanesWhen going downhillWhen accelerating from a stop30s
- Q15What is the purpose of the 'Neutral' gear in an automatic transmission?Disengages the engine from the wheelsLocks the transmission to prevent movementActivates engine brakingAllows the vehicle to move backward30s
