Contaminants can enter your transmission fluid system in the manufacturing process. They can also enter the transmission through the vent, or through the dipstick and fill tube during fluid level checking/filling. Most of the time, however, contaminants are the result of normal wear. These contaminants consist of metal chips and flakes from gears and bushings and fine fibrous material from clutch facings. Automatic transmission filters protect automatic transmissions against contaminants in the transmission fluid system. Proper filtration helps improve transmission life by minimizing wear and preventing
