The torque converter helps an automatic transmission connect and disconnect from the powertrain. It functions like a clutch in a manual transmission.Know More
The torque converter is a fluid coupling that contains three elements, including the impeller, turbine and stator. Unlike a traditional fluid coupling, a torque converter is able to multiply turning power.
The impeller and turbine are fan-like parts that move in transmission fluid. The impeller connects to the engine and the turbine connects to transmission input shaft. Unless the vehicle is in neutral or park, the motion of the turbine makes the vehicle move. The stator sits between the impeller and turbine and aids fluid flow. The impeller spins and pushes fluid against the turbine and causes it to spin. The faster the impeller, the faster the turbine,which means the vehicle will move faster.Learn more about Transmission
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 >
The labor in hours required to replace a transmission varies between model of car and the type of replacement, but estimates vary from five hours to 16 hours to remove and install an automatic transmission. Transmission replacement is one of the most complex automotive repair tasks.Full Answer >
Most mechanics recommend transmission fluid replacement every 60,000 miles for Mazda 323 cars with an automatic transmission. Manual-transmission cars may require fluid replacement every 60,000 miles or even more frequently under heavy-duty use.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 >
