Mitsubishi DiaQueen ATF SP-III

The Mitsubishi DiaQueen ATF SP‑III specification is a synthetic transmission fluid developed according to Mitsubishi Motors requirements for electronically controlled automatic transmissions. It provides stable viscosity over a wide temperature range, rapid cooling and high oxidation resistance, allowing optimal torque maintenance and preventing overheating during intensive driving. This ATF is intended for passenger and commercial Mitsubishi models equipped with automatic transmissions of the 4‑speed, 5‑speed and DCT types, including turbocharged engines where precise friction characteristic control is important. The specification does not impose special SAPS requirements, so it can be safely used in systems with a catalyst and DPF without risk of fouling. When selecting XENUM products that meet this standard, you receive a fluid compatible with Mitsubishi’s original recommendations and ensure long‑lasting transmission reliability.
