BMW ATF M 1375.4

The BMW ATF M 1375.4 specification defines the requirements for transmission fluid for automatic gearboxes with a hydro‑mechanical torque converter that are installed in many BMW and Mini models (e.g., ZF 6HP, 8HP, 9HP, 7‑speed and 8‑speed automatics). The fluid must provide a stable friction coefficient, high thermal resistance, protection against oxidation and wear, and compatibility with seals and metal components of the gearbox, allowing smooth gear shifts and minimizing heating under high loads. The specification does not impose special requirements for SAPS, DPF or catalytic systems, as it concerns only transmission oil, not engine oil. It covers both gasoline and diesel engines coupled to conventional automatic transmissions, including turbocharged units with direct injection. When selecting a lubricant that meets BMW ATF M 1375.4, such as XENUM XA‑TRAN 6G, you receive a product that fully satisfies OEM requirements and ensures durability and reliable gearbox operation.
