About ATP Automotive

ATP Automotive has been a cornerstone of the aftermarket auto parts industry since its founding in 1955. ATP got its start when virtually no other aftermarket manufacturer was producing automatic transmission replacement parts — a gap the company was built to fill. Over the decades, that pioneering spirit has driven the brand to expand far beyond its transmission roots into a comprehensive catalog of drivetrain, engine, and chemical products trusted by professional technicians and serious DIYers alike.

Today, ATP Automotive is proudly owned by Pioneer Automotive Industries, a company with over 80 years of experience in precision engineering and manufacturing. ATP is now located in a 220,000 sq. ft. facility in Meridian, MS, shared with sister company Pioneer Automotive Industries. This modern infrastructure enables the kind of fill rates and order turnaround that professional shops depend on.

A Legacy Built on Transmission Expertise

Founded in 1955 — back when no aftermarket manufacturers offered automatic transmission parts — ATP now offers a wide array of high-quality products for both automatic and manual transmissions. Through the 1980s, the product line expanded to include repair kits, cables, and other hard-to-find items, strengthening ATP's position as a go-to name in automatic transmission service parts. Whether you're sourcing an Automatic Transmission Master Repair Kit for a full rebuild or an Automatic Transmission Control Solenoid for a targeted electronic fix, ATP's depth of coverage is hard to match in the aftermarket.

ATP has also released new numbers in the Powertrain category, including Automatic and Manual Transmission Shift, Detent, Accelerator and Clutch Cables, along with Automatic Transmission Flexplates and Manual Flywheels. The brand's Automatic Transmission Flexplate lineup is a reflection of this ongoing commitment to coverage expansion across domestic, import, and medium-duty vehicle applications.

Graywerks: Expanding Into Engine Components

In 2001, the Graywerks by ATP line was introduced. This line consists of exhaust manifolds, harmonic balancers, timing covers, and engine and transmission pans. The Graywerks sub-brand marked a significant milestone for ATP — proof that the quality and engineering discipline honed in transmission parts could be carried over into broader engine applications. ATP has released new numbers in the Engine Harmonic Balancer category, expanding coverage to 25 million vehicles on mid and late model applications, including domestic, import, and medium duty vehicles. Shop ATP's growing lineup of Engine Harmonic Balancers for vehicles where balancer replacement is critical to protecting the crankshaft and accessory drive systems.

Fluids, Additives & Leak Sealants

ATP's chemicals and additives line offers easy-to-use fluids and aerosols to stop leaks or restore power and efficiency to engines and transmissions, including stop leak products and intake system cleaners, as well as transmission protectants to reduce internal heat and wear. ATP's Engine Oil Leak Sealant products are particularly well-regarded, with formulas designed to rejuvenate dried or shrunken seals and gaskets without causing over-swelling or seal damage.
