One of the most reliable components of your vehicle is the transmission, and it's also one of the most neglected parts of regular maintenance. Premature transmission failure can be prevented in part by being sure to change the fluid and filter together as the manufacturer recommends. Fram automatic transmission filters do their part to keep your tranny running smoothly by catching foreign particles, varnish, and sludge. They help your transmission fluid do its job to lubricate and cool moving parts without interference.
