ATI Super F Transmission Fluid - Case (12)

The ATI Super F Transmission Fluid is a premium synthetic automatic transmission fluid engineered for high-performance vehicles and demanding street or racing applications. If you're building or maintaining a modified transmission—whether a stock rebuild with upgraded internals or a fully constructed performance unit—ATI Super F delivers the thermal stability and film strength required to protect clutch packs, bands, and bearing surfaces under sustained load. This case of 12 quarts ensures you have adequate fluid for a complete transmission service with reserve for top-offs, making it the practical choice for serious enthusiasts and professional shops.

ATI Super F is formulated with synthetic base stocks and a carefully balanced additive package that maintains viscosity consistency across wide temperature ranges—critical when transmission oil reaches 200°F or higher during hard acceleration or track use. The fluid resists oxidation and sludge formation, extending the service life of internal components and reducing the risk of varnish buildup on valve bodies or solenoid spools. Superior anti-wear properties protect both OEM and aftermarket friction materials, while the detergent package keeps hydraulic passages clean and ensures precise pressure regulation throughout the torque converter and planetary gearsets.

This product suits transmission builders, performance shops, and DIY mechanics upgrading or servicing automatic transmissions for street, strip, or road-course duty. Whether you're rebuilding a TH400, 4L60E, 4R70W, 727, or modern multi-speed transmission, ATI Super F meets the friction and anti-shear demands of stock-class racing and modified powertrains. Always consult your transmission manufacturer or builder's fluid specification—some newer OEM vehicles require Type WS or Dex-Merc equivalents—but for classic performance, street rod, and race-focused builds, ATI Super F remains the benchmark choice among experienced technicians.
