In the earlier days, cars came with manual transmissions only. Cars like Ford Model T had only two forward gears and one reverse, controlling the engine with the help of pedals. However, manual transmissions worked under the same principle like modern cars. Gradually as the number of cars increased, engineers began thinking of equipping the vehicles with automatic transmission. With the help of such transmissions, car gears would shift automatically from one to another.
Today, almost all car manufacturers are producing cars which come with an automatic transmission. Recently it was found out that Chrysler Group is planning to invest $843 million in its Kokomo and Indiana manufacturing plants to produce automatic transmission for new front-wheel drive. All over the world, even in US cities like Chantilly and Oakton people prefer cars with automatic transmissions since these offer "no-fuss, no-muss" form of gear shifting.
The important components of an automatic transmission:
1. Torque Convertor: This is the key to the modern technology of automatic transmission. It replaces the clutch in the manual transmission. The best advantage of the torque convertor is that it helps to multiply the turning power of the engines of the vehicle. It is connected to the motor with the help of a metallic rod which is often known as the input shaft. However, it is important to mention that there is no direct connection between the transmission and the engine. This section has two fans with their faces pointing towards one another. Both these components have blades that catch the transmission fluid and this causes them to spin.
2. Planetary Gearsets: These are different gears of various sizes and are given the name of planetary since they are circular in shape in revolve around the central gear which is commonly known as a sun-gear.
3. Bands, Clutches, and Servo Pistons: Most vehicles use a multiple-disc operation. In such setup, a number of friction discs are placed in-between the steel plates. On the other hand, there are some cars which use only transmission bands.
It is imperative to say that since these are parts of the car engine it is possible that they may face mechanical snags anytime. People residing in US cities like Vienna and Chantilly, who often use their cars, face such problems with their vehicular engines.
