AUT 201 Week 2 quiz

Which of the following describes the operation of the hydraulic control system and gear train in an automatic transmission?

The transmission can automatically couple and uncouple from the engine when needed, much like a clutch on a manual transmission vehicle.

Technician A says that a transaxle must have a type of differential assembly to allow the front wheels to turn at different speeds while driving around a curve. Technician B says that a conventional rear-wheel drive vehicle will typically use a differential assembly that is located in the rear axle assembly. Who is correct?

Technician A says that parallel hybrid systems use transmissions that allow both the internal combustion engine and electric motor to drive the wheels at the same time. Technician B says that all hybrid systems use a variable pulley diameter continually variable transmissions to connect the internal combustion engine to the electric motor. Who is correct?

Technician A says early torque converters always had some slippage, so in the late 1970's and early 1980's, manufacturers added a lockup clutch to the torque converter. Technician B says typically, torque converter lockup will only happen when the vehicle is under an appropriate load and speed. Who is correct?

Technician A says the transmission should be able to adapt the engine torque to meet the speed and power demands of the vehicle. Technician B says the torque converter does not adapt in this way. Who is correct?

In a lock-up converter the _______ and _______ are locked together, when conditions are suitable.

Which of the following was used to connect the engine crankshaft to the input shaft of early automatic transmissions?

_____ is/are often used in the final drive of front-wheel-drive transaxles and also in conventional final drives on rear-wheel-drive vehicles.

Overdrive ratios typically are used to decrease fuel economy while travelling at highway speeds by slowing the engine speed.
