More about the ATP Automotive brand
Founded in 1955 in Chicago, ATP began as a supplier of high-quality automatic transmission replacement parts. Over time, it expanded its product range to include filter and repair kits, cables, flywheels, gear rings, cabin filters and chemical products. In 2001, it launched the Graywerks line of exhaust manifolds, balancers, timing covers and crankcases. In 2014, the brand adopted a new logo and became known as ATP Automotive.
In 2017, ATP’s assets were acquired by The Lodi Group (Monterey, Mexico), resulting in the creation of Automotive Technology Products LLC. Today, the company is located in a 20,000 sq. ft. facility in Meridian, Mississippi, which it shares with sister company Pioneer Automotive Industries. ATP continues to offer high-quality aftermarket solutions as part of a group focused on powertrains and transmissions.
