Valvoline Dexron III/Mercon is a conventional automatic transmission fluid sold in six one-quart bottles. It meets the older Dexron III and Mercon specs, so it suits vehicles from roughly the 1990s and early 2000s that call for those fluids, plus power steering and hydraulic systems that specify them. It is not a licensed Dexron VI or Mercon V fluid, so late-model transmissions that require those specs need a different product. Owners like the six-quart pack for a full drain and refill, but some report bottles arriving leaking or dented.
