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.Know More
The components of a transmission require the constant circulation of transmission fluid to reduce the friction between the moving parts and to cool the entire system. In an automatic transmission, this circulation of fluid is controlled by solenoids. When it's time to shift between gears, the solenoids receive an electrical signal and redirect the flow of the fluid to the desired gears. In modern vehicles that have an on-board computer to control and monitor the vehicle in its operating state, the solenoids are controlled by the computer.
The purpose of a transmission is to deliver power from the engine to the drive shaft. Every engine has a range of revolutions per minute within which it runs best. The transmission ensures that the engine keeps operating within that suitable rpm range, regardless of the speed of the vehicle. It operates through a number of gear combinations and changes gear ratios to suit the condition of the engine. Automatic transmission is a kind of vehicular transmission system that has the capability to automatically adjust gear ratios within the system, thus freeing the driver from manually changing gears.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 >
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 >
There are several reasons why an automatic transmission makes a whining sound. The transmission pump makes this sound as pressure increases with rotational speed. This occurs while stationary and increases as the vehicle accelerates. A clogged transmission filter creates a similar sound to a whining pump. If the vehicle is low on transmission fluid, it can also cause a whining sound, accompanied by gear shifting problems and other habitual issues.Full Answer >
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.Full Answer >
