A five-speed automatic transmission refers to the number of gears in a car's transmission. It means that the transmission has the potential to automatically switch through five gears.Continue Reading
In cars with manual transmissions, drivers have to physically shift through gears while driving. Automatic transmissions offer an easier driving experience. Instead of physically shifting gears, drivers can simply put the car in drive, press the pedals and steer.
Automatic transmissions were developed during the 1920s, but did not become popular until 1950s. Today, most car manufacturers offer this gear system. During the early years of its creation, automatic transmissions had a maximum of three gears, but advancements in automotive engineering resulted in cars with five standard gears. Some vehicles can have up to eight or more gears.
Gears are important in driving because they affect the efficiency of a car. The higher the gear, the quicker the vehicle speed and the less work the engine has to do. Having a five-speed automatic transmission helps boost a car's fuel economy. However, not many drivers reach the fifth gear within the city. In most cars with a five-gear system, switching to the fourth gear is often enough for most travel.Learn more about Transmission
An automatic transmission works by using a system of planetary gears that lock and unlock to accomplish gear changes. Automatic transmissions use a torque converter, rather than a clutch, to disconnect the transmission from the engine when the car is coming to a stop.Full Answer >
Common symptoms of automatic transmission problems include gear slippage, transmission fluid leakage or transmission fluid that is dark and smells burnt. In addition, rough or clunky gear changes can also be a sign of transmission trouble.Full Answer >
To diagnose an automatic transmission problem, check the level of the transmission fluid to make sure the vehicle is not losing fluid, check the transmission system for leaks, and check the transmission filter to make sure it isn't clogged. If there are no problems in any of these areas, it is likely that the transmission needs rebuilding.Full Answer >
To diagnose automatic transmission problems, check for a low transmission fluid level, which leads to poor shifting of a vehicle and gradually causes damage to the transmission, and check for leaks in the filler tube base, the drain hole below the transmission, and the area between the engine and transmission. Also check for a clogged filter, and replace the filter if necessary.Full Answer >
