GA6HP26Z Automatic Transmission Filter Kit

The BMW Genuine Parts 24152333899 is an automatic transmission filter kit specifically designed for GA6HP26Z (6HP-26) transmissions equipped with a steel oil pan. It is explicitly stated that this kit is not compatible with transmissions featuring plastic oil pan/filter assemblies. This kit is a critical component for any transmission service on your BMW. The transmission oil filter's function is to prevent particulate matter from entering the valve body, which can lead to shifting problems such as delayed or harsh shifts, or even a complete lack of gear engagement in severe cases. A clogged filter can also restrict fluid flow, potentially starving the transmission pump and causing a whining noise. Regular replacement of the transmission filter is recommended, especially during fluid service or when major transmission components like the torque converter or valve body are replaced. For optimal service life, BMW recommends a drain and fill service every 30,000 miles, during which replacing the filter is advised. This kit typically includes essential items such as an automatic transmission oil pan magnet, oil pan gasket, transmission filter with sealing o-ring, screw plug with gasket ring, and an auto trans drain plug. This genuine BMW part ensures the quality and fitment expected from the original equipment manufacturer. This filter kit is compatible with various BMW models including the X5 (2004-2006, 4.4i, 4.8is, and 2010-2013 M models), Alpina B7 (2007-2008), and X6 (2010-2014 M models), all featuring the GA6HP26Z transmission. Note that one customer reported receiving an incorrect fill plug and gasket, but FCP Euro provided the correct replacements upon contact.
