What Brand is BMW Transmission Fluid?
1 Answers
BMW's original dedicated transmission fluid is ZF–Lifeguard-Fluid(6-HP), which is a fully synthetic formula. There are strict requirements for the use of automotive transmission fluid. If other types of transmission fluid are used, it may cause premature damage to internal transmission components, issues with gear shifting, and other phenomena. More details are as follows: 1. Low-quality or counterfeit transmission fluid has poor temperature resistance, is prone to oxidation, and can lead to sludge and residue buildup, clogging the filter, reducing transmission fluid pressure, affecting shift quality, and easily causing cavitation, resulting in unstable oil pressure. It can also damage friction materials, sealing rubber, and metal components, ultimately leading to abnormal transmission operation. 2. The grade of automatic transmission fluid increases with higher numbers. The viscosity grade of gear oil (also known as manual transmission fluid) is generally selected based on the temperature conditions of different regions or seasons. In high temperatures, higher viscosity gear oil is chosen; conversely, in low temperatures, lower viscosity gear oil is selected.
