About ATP Automotive

ATP Automotive has been one of the most recognized names in aftermarket drivetrain components for decades. Founded in 1955 at a time when no other aftermarket manufacturer was producing automatic transmission replacement parts, ATP stepped in to fill a critical gap for mechanics and vehicle owners alike. Over the ensuing decades, the brand built a reputation for precision engineering, dependable performance, and broad vehicle coverage that few competitors could match.

Today, ATP Automotive is proudly part of Pioneer Automotive Industries, a company with over 80 years of experience in precision engineering and manufacturing. That deep institutional knowledge informs every part that leaves ATP's facility. The brand serves customers and distributors throughout North and South America, continuously expanding its lineup to keep pace with the ever-changing automotive landscape.

A Catalog Built Around Drivetrain Integrity

What started as a focused collection of automatic transmission components has grown into a comprehensive drivetrain parts catalog. ATP's product line today spans automatic transmission filter kits, repair kits, cables, flywheel and ring gears, cabin air filters, and chemicals — making it a genuine one-stop source for transmission-related service and repair.

Among the brand's most trusted offerings are Automatic Transmission Flexplates, engineered from high-quality steel with precise bolt hole spacing and ring gear tooth counts that mirror the original equipment part. For manual transmission applications, ATP's Clutch Flywheels deliver the same commitment to precision fit and factory-spec balance, providing a smooth friction surface for proper clutch engagement and long service life.

Keeping transmission fluid clean is fundamental to longevity, and ATP's line of Automatic Transmission Filters addresses that need with direct-fit kits designed to meet or exceed OEM specifications. Complementing the filter lineup, ATP also produces Transmission Mounts — a category covered in ATP's own dedicated Engine and Transmission Mount Catalog — engineered to dampen vibration and keep the drivetrain securely located in the chassis.

Rounding out the core drivetrain portfolio, ATP's Automatic Transmission Shifter Cables cover a wide range of import and domestic applications, ensuring precise, reliable gear selection with every shift. The brand has continually expanded its cable coverage to include shift, detent, accelerator, and clutch cable applications across mid and late-model vehicles.

Engineering Standards That Stand the Test of Time

What sets ATP Automotive apart is not just the breadth of its catalog but the standards behind it. Products are tested to meet international quality benchmarks, and the brand's commitment to accurate coverage — without consolidations that compromise fitment — means technicians and DIYers can install ATP parts with confidence. Whether you're performing a routine service or tackling a full transmission rebuild, ATP Automotive's lineup offers the reliability and coverage to get the job done right.
