Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This filter fits A5S325Z automatic transmissions on BMW E46 323i 323ci 325i 325ci 328i 328ci 330i 330ci . E39 525i 528i 530i. E85 Z4 2.5i Z4 3.0i. This kit includes the transmission filter and gasket.

  • 1 x 24341423376 - transmission filter
  • 1 x 24101423380 - gasket for transmission filter

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace this and all the other components of the oil separator system to prevent damage to all the aspects of your engine. As long as you have everything off, you can rest assured that new parts will last and be reliable.

Having your oil pressure light come on can mean very serious problems. Or it could just be this switch that fails several times over a car's lifespan. By no means should you ignore the warning light but replacing this sensor could be the actual culprit. The other problem with this switch is that oil can leak past its seal. With the oil under a lot of pressure at this point, the oil loss can be a serious concern. It's a simple replacement when doing most oil change work.

This Oil Pressure Switch fits the following BMWs:
