What are the disadvantages of an automatic gearbox?
This is proven technology and as long as they’re serviced at the prescribed intervals, they should be reliable. Disadvantages: An automatic gearbox tends not to be as fuel efficient as a manual or a direct shift gearbox.
How does the gearbox work in a car?
This uses hydraulic fluid to transmit drive between the engine and gearbox. It means you simply slot the gearlever into ‘D’, press the accelerator and the gearbox does the rest, changing gear when its electronics say it’s appropriate.
Which is more efficient automatic gearbox or CVT?
Now for anyone who wants to let the car’s electronic brain take the strain, there are a variety of different self-shifting gearboxes available. Thanks to advances in technology, automatic gearboxes have become far more efficient. And as they can accommodate more ratios – some have 10 speeds – they help drivers to save fuel too.
What are the gears in an automatic transmission?
Gears: Even though you’re not shifting them, an automatic transmission has gears. They are broken into main gears and planetary gears. You need all of these to be able to drive.
What does it mean when your transmission jolts between gears?

What causes a car to jerk when shifting gears?
Transmission Fluid Level – A great place to start looking is the transmission fluid. Transmission fluid that is at the wrong fill level will cause the transmission to behave differently. If the fluid gets too low, than the car won’t move at all. See: Low Transmission Fluid Signs
