Exam 3: General Theories of Operation

The ____________________ directs fluid flow from the turbine to the impeller.

The ____________________ seals and allows fluid flow through passages in the valve body.

____________________ is fluid breakdown.

Technician A says a one-way clutch in the stator allows it to remain stationary when it is not needed. Technician B says the flow of fluid from the impeller to the turbine is directed with the aid of the stator. Who is correct?

Describe an orifice and its action.

Technician A says electrical switches are used to open and close electrical circuits. Technician B says electrical switches are used to control the operation of other devices. Who is correct?

Driving a vehicle with a very low level of ATF is not harmful to the transmission.

Engine performance can affect torque convertor clutch operation.

The ____________________ is a spring steel cone-shaped plate.

The ____________________ drives the impeller, which then drives the turbine.

Technician A says the valve body senses and responds to engine and vehicle load. Technician B says valve bodies house many different valves that are moved by the gear selector. Who is correct?

​The TCM uses ___________-_________-__________ to activate the pressure control solenoid.

Technician A says that some hybrid vehicles rely on one simple planetary gear set for their transmissions. Technician B says that a hybrid transaxle may contain two motor/generators. Who is correct?

A(n)____________________ is a small opening or restriction.

All transmissions have a throttle valve linkage that controls forced downshifts.

It is not important to use the recommended ATF in the transmission.

A(n)____________________ is when two or more planetary gear sets are used.

​Pressure testing reveals low pressure in all gears. Technician A says using a reverse stall test forces the pump output to maximum pressure. Technician B says a reverse stall test will determine whether the pump output is low. Who is correct?

Overdrive improves fuel economy but increases engine noise.

From a single planetary gear set, there are two possible reverse speeds and how many possible forward speeds?
