ATP Auto Parts

ATP Replacement Parts


ATP, Inc was founded on July 1, 1955. The company was born to service the automatic transmission replacement parts needs of installers. At the time, there were no aftermarket manufacturers providing these parts. Today, ATP is still privately held.

Located in a northern suburb of Chicago, Illinois, the 92,000 sq. ft. facility allows for quick order turn and a fill rate consistently over 98%. And keep in mind, they don't just sell transmission filters, but a complete line!

Currently, the product line consists of automatic transmission filter kits, repair kits, exhaust manifold kits, harmonic balancers, timing covers, cables, flywheel and ring gears, interior vent filters and chemicals.
