Purpose of the Oil Pump
Provide fluid to lubricate the planetary gear set.
Provide continuous fluid to the torque converter.
Provide a volume of fluid to the clutches and brakes.
Supply operating pressure to the hydraulic control system.
Provide support for the torque converter stator (stator reaction shaft) as well as the front of planetary gear set.
all the above
The unit assembly shown in the figure is a/an :
Engine oil pump
Transmission oil pump
Steering oil pump
Engine water pump
What is the main function of the planetary gearset in a transmission?
Increases the rotational speed of the transmission
Transmits power to the wheels at different speeds
Provides the final stage of gear reduction
Creates all the different gear ratios
What is the primary role of the clutch in an automatic transmission?
To cool the transmission fluid
To provide power to the wheels
To increase fuel efficiency
To engage and disengage the engine from the transmission
Name the part (x) shown in the figure:
Direct clutch piston
Piston return spring
Planetary gear set
Direct clutch drum
What is the main disadvantage of Continuously Variable Transmission (CVT)?
Decreases engine fatigue
Allows for an infinite number of gear ratios
Smooth, responsive and quiet to drive
Limited torque capacity compared to manual transmissions
What happens if the transmission fluid level is too low?
The transmission may slip and overheat
The engine may stall
The brakes may fail
The vehicle may accelerate faster
What is the function of the valve body in an automatic transmission?
To cool the transmission fluid
To regulate fluid flow to engage clutches or bands
To increase oil pressure
To decrease oil pressure
What type of transmission is shown in the simplified diagram?
Automatic transmission
CVT
DCT
AMT
What is the function of the stator in a torque converter?
To cool the transmission fluid
To improve torque efficiency by redirecting hydraulic fluid
To increase engine speed
To reduce emissions
Where is the transmission pump typically located?
Inside the transmission case
Behind the torque converter
Near the rear axle
Under the dashboard
