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.Know More
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 in Transmission
A steptronic automatic transmission allows for an automatic transmission to have the same shifting dynamics of a manual transmission. This type of transmission is present in BMW vehicles.Full Answer >
An automatic transmission valve body is a major component of a vehicle's automatic transmission system and directs pressurized transmission fluid to a network of valves that engage appropriate clutch packs for smooth gear shifting. These valves use pressure as hydraulic signals to determine which gear set, also called band servo, to select when the vehicle changes speed.Full Answer >
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 >
A transmission solenoid is an electrically operated valve present in automatic-transmission vehicles. The valve controls the flow of fluid in and throughout the automatic transmission.Full Answer >
