6HP21 / 6HP28 Automatic Transmission Solenoid Kit

The ZF Automatic Transmission Solenoid Kit (part number 1068298047) is a crucial component for maintaining the reliability and performance of compatible ZF automatic transmissions, specifically the 6HP21 and 6HP28 series. This comprehensive kit includes a variety of solenoids (yellow, blue, and orange), a park cylinder, and a solenoid harness, providing a complete solution for transmission control module issues. By replacing individual solenoids, this kit offers a cost-effective alternative to replacing the entire valve body when solenoid control problems arise. This OE-quality kit is manufactured in Germany, reflecting ZF's commitment to high standards. The kit's components are specified for the 6HP21 and 6HP28 transmissions, with a detailed breakdown of compatible main part lists provided for precise matching. The product also notes that internal transmission parts can vary even if the external appearance is similar, emphasizing the importance of matching the transmission's main parts list. Fitment is extensive, covering various Jaguar XK8 models from 2003-2006, and a wide range of BMW models including the X5 (2007-2013), 5 Series (2008-2010), 6 Series (2008-2010), and 7 Series (2009-2012), among others. Specific notes on fitment include the BMW X5 4.8i (2007) being through 12/2006 and the BMW X5 M (2010) being from 04/2010, highlighting the need for careful verification. It is important to note that installation should only be performed by qualified personnel, and solenoid valves may require calibration or programming in the transmission control unit after installation.
