AT3 Synthetic Dex/Merc Transmission Fluid 1 Qt.

The AT3 Synthetic Dex/Merc Transmission Fluid 1 Qt. by DRIVEN RACING OIL is purpose-built for drivers and mechanics who demand precision-engineered fluid performance in modern automatic transmissions. This synthetic formulation is specifically designed to meet Dexron and Mercon specifications, making it the ideal choice for vehicles requiring dual-specification compatibility without compromise. Whether you're maintaining a daily driver or fine-tuning a modified build, this transmission fluid delivers the thermal stability and shift consistency that separates quality maintenance from guesswork.

DRIVEN RACING OIL formulated AT3 with advanced synthetic base stocks that resist viscosity breakdown under sustained heat and pressure—critical for high-performance applications or vehicles with modified torque converters and valve bodies. The fluid maintains consistent film strength across a wider temperature range than conventional alternatives, reducing wear on clutch packs, seals, and hydraulic components. Superior oxidation resistance extends drain intervals and protects against deposit formation, which is especially valuable in transmissions operating at elevated temperatures during aggressive driving or towing scenarios. The 1-quart container size offers convenience for top-offs, system flushes, or maintaining a spare on the shelf.

Mechanics and enthusiasts working on General Motors, Ford, Chrysler, and other OEM platforms that call for Dexron III, IV, VI or Mercon fluids will find this synthetic solution compatible with both legacy and modern transmission designs. The dual-specification approval eliminates the need to stock multiple fluid types, simplifying maintenance workflows for shops and fleet operators. Always verify your vehicle's specific transmission fluid requirement in the owner's manual before use; this formulation is engineered for automatic transmissions only and is not suitable for manual gearboxes or continuously variable transmissions (CVTs).
