These filters help capture abrasive particles such as metal shavings or debris caused by the transmission operation, preventing them from entering or blocking fluid flow that may cause damage to the transmission's internal components. They deliver efficient filtration and outstanding fluid flow to and from your vehicle's transmission. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
