automatic transmissions section 1 test: CH 1, 2, 3, With Complete Verified Solution

automatic transmissions section 1 test: CH 1, 2, 3, With Complete Verified Solution Which of the following DOES NOT describe the purpose of a vehicle's drivetrain? It increases the power available to the drive wheels. Power is created in the engine (and/or motor) the drivetrain is responsible for taking the power from the engine and transferring it to the wheels. Which of the following can be used to multiply torque? pulleys, gears levers Which of the following IS NOT a true statement about gear ratios? Note: One of the book answers was eliminated as it was misleading. A high (numerical) ratio allows for greater torque multiplication. in gear systems, speed reduction means torque decreases The engine's power is transmitted to the transmission through a fluid coupler, called the: torque converter Most automatic transmission equipped models use torque converters but there are a few models that have incorporated a start clutch While discussing engine vacuum: Technician A says it always increases as engine load decreases. Technician B says it is highest at deceleration. Who is correct? both Engine vacuum is used in many of the powertrain control systems to determine the load on the engine Technician A says through selection of the proper gear ratio, torque applied to the drive wheels can be optimized
