Exam 42: Electronic Automatic Transmissions

Describe what happens when the transmission goes into limp-in mode.

Which of the following is NOT a TCM input signal?

How does a pressure control solenoid regulate transmission pressures?

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

In a vehicle with a dual mode transmission, during normal driving under light loads, the vehicle is driven solely by the engine.

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

The customer complains of shuddering that occurs at light throttle just when the vehicle reaches 45 mph. The shuddering lasts for a few seconds then stops until the vehicle slows down and then speeds back up to 45 mph. The problem could be ______.

When a Toyota/Lexus hybrid is driving on electric power, if more torque is needed, _____ is activated to start the engine.
