Mitsubishi DiaQueen ATF J2

The Mitsubishi DiaQueen ATF J2 specification is the official transmission fluid standard developed by Mitsubishi Motors for AT‑type automatic gearboxes (including 4‑speed, 5‑speed and DCT systems) in passenger and commercial models of the brand. The fluid meets requirements for high thermal resistance, oxidation and wear stability, provides an optimal friction coefficient for smooth gear shifts and protects seals from softening. ATF J2 is compatible with Mitsubishi gasoline and diesel engines, including turbocharged units, and contains no sulfate or phosphate additives, allowing safe operation with catalysts and diesel particulate filters (DPF). When selecting XENUM products bearing the DiaQueen ATF J2 label, you receive a synthetic fluid that conforms to this standard while also meeting the requirements of previous Mitsubishi ATF J‑2 approvals, ensuring backward compatibility without loss of protective properties.
