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.Know More
A qualified automotive technician can locate the source of whining sounds and diagnose contributory mechanical issues. A part of preventive maintenance is to have the transmission inspected every two years or 30,000 miles, and to have a transmission flush performed.
Transmissions contaminated with dirt and grease experience symptoms similar to transmission failure. A flush removes the dirty fluids, grime and residue from the converters and cooler lines, and it replaces it with fresh fluids. In some cars, this enhances the function and preserves the life of the transmission.
Keep in mind that some vehicles do not benefit from a transmission flush. With certain cars, a flush may cause damage to the transmission’s valves and seals. Car owners need to follow the instructions of the manufacturer to ensure the vehicle receives the proper preventive maintenance.Learn more about Transmission
The most common indicators that an automatic transmission linkage is faulty are frequent overheating of the engine and significantly reduced transmission fluid. It is also likely to hear clanging and banging noise during operation. Faulty automatic transmission linkages occur from regular wear and tear or due to lack of regular maintenance.Full Answer >
Changing the fluid in a Ford Explorer's automatic transmission requires dropping its pan, draining the old fluid and replacing the filter. The process requires an even surface to work with and an intermediate set of tools to use, such as a drain pan and socket set.Full Answer >
An automatic gearbox uses a system that includes fluid coupling to transfer the engine's power to the transmission and a set of planetary gears that are locked or unlocked in different combinations to engage different gears. One of the most complicated components in modern vehicles, an automatic gearbox includes mechanical, hydraulic, electrical and computer systems.Full Answer >
Transmission shudder is usually caused by a lack of transmission fluid or a slipping torque converter clutch. Contaminants in the transmission fluid may also lead to transmission shudders, but because the transmission is a closed system, dirty transmission fluid is usually a sign of a larger problem.Full Answer >
