On account of Regular Motors introduced them in 1937, many cars include come with automatic transmissions. The alternative to sample or album transmissions, cars with an automatic transmission shifts gears automatically. Many drivers prefer this type of transmission for it frees up their hands and is simpler to function.
How It Works
The leading end of the transmission is to letter force from the engine to the wheels. It regulates the competency so the motorcar drives at the optimum revolutions per minute, depending on the gear. It is normally connected to the back of the engine. Automatic transmissions admit a impel gear, while some admit higher gears such as inaugural or moment gear. There is very a impartial gear, which eliminates the influence between the engine and the wheels. Another gear is reverse in which the transmission sends potency from the engine backward to the wheels. Lastly, there is stadium, in which the transmission locks the wheels in field so it cannot be moved.
Components
Automatic transmissions consist of the adjacent components: planetary gear sets, the hydraulic action, seals and gaskets, the torque converter and a throttle cable. Transmission fluid has a reddish color so be sure to check for any reddish leaks under your car. Moreover, if you notice that the fluid has a muddy color or gives off a burnt odor, make sure you have it checked by a technician. If you notice the shifting to be rough during driving or hear noises when it shifts, it should be looked at immediately.
Advantages
The planetary gear sets are used to bequeath the varying forward and reverse gear ratios. The hydraulic step uses the oil pump to letter transmission fluid to the series of clutches and bands so they can ride the gear sets. The seals and gaskets are used to prevent oil leakage. The torque converter allows the motorcar to come to a bar with the engine running. Last of all, the throttle cable determines when the engine should shift based on its speed.
Maintenance
Transmission fluid should be changed every 25,000 miles with the manufacturer's suggested fluid.Automatic transmission vehicles are generally found to be easier to function than standard transmissions. One does not have to worry about shifting gears, which allows both hands to be on the wheel. Moreover, with fewer pedals, only the right foot is needed to function the vehicle.
Disadvantages
The downside of automatic transmissions is they do not have the power of a manual transmission. Another factor is that vehicles with automatic transmissions generally cost more and seem to need more repair work. Moreover, the fuel economy is better on cars with manual transmissions.
