BMW claims their transmission fluid to be a "lifetime" fluid, however is recommended to be changed every 60,000 miles to ensure a longer transmission life. Though not exposed to the same level of heat and contamination as engine oil, transmission oil still breaks down over time due to heat and becomes contaminated as your transmission wears. Old contaminated oil can lead to excessive wear and tear on sensitive transmission components which could lead to slow shifting, slips, and even complete failure. This is also true for the transmission filter. The filter removes metal particles from the transmission fluid and eventually begins to clog, preventing fluid from passing through the filter easily. This leads to excessive wear and a reduced transmission lifespan if not changed. This high-quality Meyle transmission filter is quintessential for a correct and full service. Included: Meyle Transmission Filter Transmission Pan Gasket Drain Plug Installation Hardware Not sure if this kit is right for your BMW?
