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.

  • Step 1

    Simply add AT-205 to the system that has a leak - engine, transmission, power steering, differential or hydraulics (anything except brakes).

  • Step 2

    The product is mixed with the oil and circulated during operation, thus reaching all seals that need treatment.

  • Step 3

    AT-205 Re-seal acts as a plasticizer - restoring the elasticity and flexibility of hardened or dried seals.

  • Step 4

    If the seal is not severely torn or deformed, the leak will usually stop within 5 hours of normal driving, saving you time and money on expensive service.

    • Stopped oil seal leak on Ford Capri

      I changed the oil. I added AT-205. We drove around all weekend. I left the car. In the morning there were no usual 3-4 drops of oil on the floor.

    • VW 1 from 1985

      I never imagined that an additive could restore the deposits so well. I put it in the engine and transmission. I highly recommend it.

    • 1975 Chevy Impala

      It restores all kinds of deposits in the engine and transmission. And the money saved is a four-digit number. I searched a lot. In my opinion, it is the best product.
