High-Temp ATF Case/12

Redline OIL High-Temp ATF Case/12 is a synthetic transmission fluid engineered for demanding driving conditions where heat management and fluid stability are critical. This 12-quart case delivers Dexron III and Mercon-compatible formulation in individual 1-quart bottles, making it ideal for mechanics, fleet operators, and serious enthusiasts who need reliable ATF in bulk.

The high-temperature synthetic blend resists viscosity breakdown under sustained heat exposure, a critical performance factor in vehicles experiencing extended highway driving, towing loads, or performance modifications that elevate transmission operating temperatures. Synthetic ATF maintains stable film strength across a wider temperature range than conventional mineral oils, reducing wear on clutch packs, seals, and hydraulic components. The Dexron III / Mercon dual compatibility covers the vast majority of domestic and imported automatic transmissions manufactured since the 1990s, eliminating guesswork during specification verification.

Bulk purchasing in quart bottles suits professional shops and DIY builders performing multiple transmission services or maintaining a fleet without waste. Individual quart format allows controlled dispensing and extends shelf life compared to opened bulk containers. This configuration works equally well for routine transmission maintenance, post-rebuild fluid charges, or fluid top-offs on high-mileage vehicles transitioning to synthetic fluid.

Redline OIL's transmission fluids are formulated with synthetic base stocks and proprietary additive packages designed to support modern transmission metallurgy and clutch materials. The case format minimizes per-quart cost relative to retail shop bottles while maintaining factory-sealed integrity of each unit. Total weight of 24.39 lbs reflects 12 standard 1-quart bottles plus packaging, suitable for standard shipping and storage.
