Exam 42: Electronic Automatic Transmissions

A homemade tester for checking the operation of the ____________________ can easily be made from an old wiring harness and a few simple switches.

Which of the following is NOT a component of the Toyota/Lexus hybrid transaxle?

What is the function of the start clutch in the Honda CVT transaxle?

When a Toyota/Lexus hybrid vehicle is operating under heavy loads, ______.

How does a pulse width modulated solenoid control transmission pressure?

The dual mode hybrid transmission contains all the following components EXCEPT:

What happens when the transmission mode switch is set to Power?

An ____________________ converts analog AC signals into digital DC square waves.

The Toyota/Lexus hybrid transaxle uses a _________________ that combines the power from the gasoline engine with the power from the electric motors.

The application of the TCC [torque converter clutch] is controlled by the ______.

Normally, the shift solenoids receive voltage through the ignition switch and are grounded through the ____________________.

Technician A measures sensors only when they are cold. Technician B uses dielectric grease on electrical connections to prevent corrosion. Who is correct?

The MAP sensor is connected to the PCM. The TCM gets manifold pressure information from the PCM through ____________________.

If the TCM loses source voltage, the transmission will enter into ____________________ mode.

How does adaptive learning improve the shift quality of an electronically controlled transmission?

The _____ is a voltage generating sensor that uses a Hall effect or PM generator to produce a signal.

The EPC (electronic pressure control) solenoid is duty-cycle-controlled by the TCM.

To test a solenoid with an ohmmeter, the transmission pan must be removed.

Two technicians are discussing EPC solenoids. Technician A says the EPC solenoid is a PWW (pulse width modulated) solenoid and receives a duty cycle signal from the TCM. Technician B says the EPC solenoid is an on/off solenoid that is turned on when the TCM sees the 3-4 upshift. Who is correct?

"Input split" and "compound split" are two modes of operation in a _____type transmission.
