An automatic transmission is an efficient way to deliver power to your car’s wheels. Compared to a manual transmission, an automatic has a higher ratio of torque to motion. This makes it more powerful and efficient than a regular transmission, allowing your car to maximize performance with little input from you.
The advantage of an automatic over a conventional transmission is that the motor can be put in either first or second gear after the shift lever is turned. This allows for easy access for maintenance or replacement operations.
When choosing an auto, there are several factors that can affect how efficiently it works for you. These include things like price, whether the auto hashift feature works well with your vehicle, and if the auto can be programmed with specific routes and speeds.

No, automatic transmissions do not have clutches
When driving at higher speed or in more rapid succession, the transmission shifts more often. This can be a good and a bad thing.
When driving at high speeds in freeway traffic or in local traffic, an automatic transmission is a plus. You do not have to worry about getting bad shift quality or quick shifting that may make you feel rushed and forced.
However, when driving on country roads or when parking your vehicle for long periods of time, then quick shifting is better than no shifting at all.
The best way to tell if an automatic transmission has a clutch is by looking for wet/dry patches on the gearshift cover.
Automatic transmissions are easier to drive
When driving at a slow speed, your automatic transmission will slip away and start shifting without you being involved. This is a nice feeling!
If you drive at a fast speed, your transmission will chug away but won’t shift accurately. When you drive at a slow speed, the car will shift faster than you are keeping up.
This is not a problem when driving at a normal speed as the car can easily adjust the gears. However, when driving quickly, the gearshift may not be precise enough to keep up with the speed.
If this happens, you need to downshift or shift higher to get another accurate chugging and shifting. It depends on if your automatic has an automatic or non-automatic clutch.
Automatic transmissions are less efficient
An automatic transmission has a clutch. A clutch allows the engine and transmission to change gears.
When driving atnormal speed, the clutch pushes the engine in and out. When you want to change gears, you pull the shift lever up and release it to make the new gear go in.
This is important so that when you get back on the road, there is a good moment of engagement between the engine and transmitted before you start pedaling again.
Dual-clutch transmissions are better than automatics
There are two main reasons to have a dual-clutch transmission. The first is that an automatic does not have a clutch. With the right programming, you can shift from park to drive!
The other is that an automatic does not have a manual shifting mode. A dual-clutch has a manual shifting mode that can be used with the parking brake engaged, making it the better choice for your ride.
Bullet point: How Does a Dual-Clutch Transmission Work
Dual-clutch transmissions work by using both gears and shifts on the same pulley. This prevents your engine from grinding when you shift or when the gearbox needs to take something out of its engine instead of just shifting on its own.
When driving in manual mode, your foot must be pulled down on one of the paddles to change gears.
Slipper clutch helps with smooth shifting
A slipper clutch helps with smooth shifting. A slipper clutch is a plate or disk that moves back and forth as the transmission shifts.
When shifting into a higher gear, the slipper clutch forces the right side of the transmission to move more than the left. This helps with smooth shifting, as the right side is not trying to shift as much as the left.
A slipper clutch was originally designed for cars that needed to go from a high gear to a lower gear quickly. This was important, because people then would need to drive away before replacing the oil and performing another oil change.
Today, they are available in all major generation 3 and 5 cars. They help with keeping up speed while having a no break-up feeling when changing gears. They also help with programming into your car’s automatic mode so that they do not take over when in motion.
Torque converter helps with smooth driving
When driving at higher speeds, the transmission needs to shift into second or fourth gear. When driving at a low speed, the transmission needs to shift into first or second gear.
A torque converter helps with this by automatically shifting into fourth or first when needed. Most automatic transmissions have a torque converter, and it can be an easy fix for smooth driving.
Its function may not be noticeable at high speeds, but it makes a huge difference when negotiating hills or slippery roads. Having the automatic shift into first or second helps with control when changing gears at lower speeds than speed.
An automatic transmission is more suited for city driving
When you drive on the highway, your car will shift into a higher gear. This is called a shift up or shift down.
On the highway, your speed can affect how many gears you need. At high speeds, more gear requires more centrifugal force which requires more power to operate.
The larger number of gears you have in your car, the more power you require to move it. This is why having a transmission with fewer gears is better for driving- having too many gears can cause misalignment of parts and incorrect movement of the vehicle.
When approaching traffic signals or stop signs, shifting into a higher gear can help save some speed compared to going in a lower one. Additionally, when turning left or right, shifting into a higher gear helps keep momentum while shifting out into traffic.
An automatic transmission is more suited for highway driving
When driving at higher speeds, the transmission needs to shift into a new gear. When driving at a slower speed, the automatic transmission does not have to shift. This is where the difference in gears comes in.
When driving at a high speed, your car needs a full gear to move. When driving at a slower speed, such as when traveling on roads, you can switch from first to last gear without much of a problem.
The problem comes when trying to merge or turn off your vehicle. With no change in gears, you may end up causing damage to your vehicle or someone else’s. You would have to manually shift into another gear if that happened!
An automatic transmission does have a clutch which must be used when shifting into a new gear.
