How Automatic Transmissions Work
by Karim Nice
If you have ever driven a car with an automatic transmission, then you know that there are two big differences between an automatic transmission and a manual transmission:
There is no clutch pedal in an automatic transmission car.
There is no gear shift in an automatic transmission car. Once you put the transmission into Drive, everything else is automatic!
Both the automatic transmission (plus its torque converter) and a manual transmission (with its clutch) accomplish exactly the same thing, but they do it in totally different ways. It turns out that the way an automatic transmission does it is absolutely amazing!

Notice that the first gear ratio listed above is a reduction -- the output speed is slower than the input speed. The second is an overdrive -- the output speed is faster than the input speed. The last is a reduction again, but the output direction is reversed. There are several other ratios that can be gotten out of this planetary gear set, but these are the ones that are relevant to our automatic transmission. You can try these out in the animation below:

So this one set of gears can produce all of these different gear ratios without having to engage or disengage any other gears. With two of these gearsets in a row, we can get the four forward gears and one reverse gear our transmission needs. We 'll put the two sets of gears together in the next section.
Gears
This automatic transmission uses a set of gears, called a compound planetary gearset, that looks like a single planetary gearset but actually behaves like two planetary gearsets combined. It has one ring gear that is always the output of the transmission, but it has two sun gears and two sets of planets.
Let 's look at some of the parts:
How the gears in the transmission are put
Now that we’re ‘up and running’, it is now time to familiarize yourself with the location, as well as feel, of passing through the gears. If you’d prefer, you may learn to shift the gears without the car running (while having the clutch pushed-in). Or perhaps, you could familiarize yourself while sitting in the passenger seat, shifting gears with someone else driving the car and operating the clutch. Be sure to place the ‘stick’ all the way fully into the gear—until it won't go any more—but don't force it. If you stop halfway, you will hear an incredibly unpleasant grinding sound when releasing the clutch which means your car is not properly in gear.
The manual gearbox just gives you a lot more control over your car. Like safermotoring.co.uk says, on one of their reports, "Many veteran drivers who have experience of both types of transmission systems insist that a
Another reason for driving manual transmissions is that it is just more fun! Manual transmissions will make your driving more interesting. Race drivers use the manual transmission to take driving to a higher level for maximum performance.
Transmission – Whether manual or automatic, the transmission is responsible for shifting gears in your Sonoma, and if there is a problem with it, you may find yourself stuck in one gear. You change your transmission fluid and filter regularly, but at some point, you may need to replace the transmission or its components. We carry transmission parts for your
Possessing the knowledge of how all the parts in the car work together in order to make the car go is a very interesting concept, at least in my opinion. It was a concept that I never took the time to understand until I really wanted to find out how to drive a manual. Because I was so curious on the topic, I would ask my friends and relatives what it was like to drive a manual compared to the automatic transmission that I was used to. Almost everyone that I talked to would tell me the same thing. They always told me that it made you feel like you were more connected to your car. I wanted to experience
The transmission on your vehicle plays a vital role in keeping your vehicle on the road and working properly. If your transmission is damaged, you are not going to be able to safety drive your vehicle and if your transmission suffers serious damage, you are not going to be able to drive at all.
Have you recently purchased an automatic vehicle? Is this the first vehicle that you've ever owned? While you may have gotten some care tips from friends or relatives, they may have glossed over or forgotten about your transmission. While the transmission is a mysterious device for some people, there are still clear warning signs that is in need of repair or replacement. Here are a few things that you should be looking for:
Purpose - To explain to the class about manual transmission cars and how to drive one.
This is one of the most common issues when dealing with a manual transmission. There are several signs of a worn out clutch some include a loud grinding sound when trying to shift gears, needing to use force to get transmission into gear, and a blocking feeling when shifting into a different gear. These are just a couple of clues suggestion a worn out clutch, if any of these signs are not very severe chances are your clutch may just need to be adjusted. If you are having any signs the clutch is messed up consider visiting a transmission repair specialist.

Little do they know that this is not a requirement and it is harming the transmission more than it is helping. Downshifting is when the driver shifts into a lower gear to slow the vehicle. This bad driving habit can cause the gears to grind and eventually wear down causing them to need to be replaced. Downshifting causes major strain and damage to the transmission and shorten the life span of the transmission dramatically.
Many drivers decide that they want a car with an automatic transmission because they do not know how to drive a car with a manual transmission, or do not want to bother with having to change gears at the right time. Unfortunately, the luxury of having an automatic transmission is that it is one more vital part of your car that can break down. Even if you are not a mechanic, it is still possible to understand some signs that your car is having transmission trouble. Knowing what to look for will give you a warning that you should take your car into the shop to have it looked at as soon as possible.
Gear uses no intermediate links or connectors to transmit the motion. The motion is transmitted in gears by direct contact. In this method the surfaces of two bodies makes a tangential contact .The two bodies have either rolling or sliding motion along with the tangent at the point of contact. No motion is possible along the common normal as that will either break the contact or one body will tend to penetrate into
The manual gearbox just gives you a lot more control over your car. Like safermotoring.co.uk says, on one of their reports, "Many veteran drivers who have experience of both types of transmission systems insist that a vehicle with a manual gearbox is safer because it gives them more control." I mean I don't know about you, but for me the more control I have over my car the better. Another con on automatic transmissions is that they are just boring to drive. I may be a little bias, because of the simple fact that I like manual transmissions a lot better than automatics, but statistics never lie.
An important component in of the ESX Mybrid system is its EMAT transmission system which utilizes two computer-controlled clutches. The EMAT system combines the smoothness of an automatic transmission with the added fuel efficiency of a manual. The driver sees the normal selection of park, drive,
