PORSCHE 000.043.20

Porsche specification 000.043.20 is the official Porsche standard for automatic transmission fluids (ATF Type T‑IV), developed to ensure stable operation of gearboxes under high torque and rapidly changing loads. The fluid must have a defined viscosity range (≈ 6.5 cSt at 40 °C and ≈ 3.5 cSt at 100 °C), high oxidation resistance, protection against wear and foaming, and be compatible with Porsche friction elements, metal and polymer seals. This standard applies to Porsche gasoline and diesel engines equipped with automatic transmissions of the Tiptronic S type, 9‑speed and 7‑speed automatics, including the 911, Cayenne, Panamera and Macan models. The fluid meets the requirements for protecting torque converters and transmission friction discs, does not require special SAPS additives, and is therefore compatible with catalysts and DPF systems without risk of contamination. When selecting an XENUM product bearing the Porsche 000.043.20 designation, technicians receive guaranteed compliance with these requirements and can be confident in the durability and efficiency of the transmission.
