Porsche ATF 3403-M115

Specification Porsche ATF 3403‑M115 is the official approval from Porsche AG for Type IV transmission fluids, developed taking into account the requirements of high‑performance Porsche automatic gearboxes, including traditional torque‑converter automatics and dual‑clutch (PDK) units. The fluid must provide stable viscosity in the range –40…+120 °C, high resistance to oxidation and thermal degradation, low friction coefficient and effective protection against wear of metallic and friction elements, allowing optimal operation of synchronizers and hydraulic systems. This standard applies to Porsche 911, Cayenne, Panamera, Macan engines and their automatic transmissions, including models equipped with the Porsche Doppelkupplungsgetriebe (PDK) system. Because ATF 3403‑M115 contains no sulfate additives, it does not affect the operation of catalysts, DPF or SAPS systems, making it safe for modern exhaust technologies. When selecting an XENUM transmission oil that meets this approval, technicians receive a guaranteed level of protection, shift smoothness and transmission durability recommended by Porsche itself.
