Engineering 722.9 Competition Build Package

The Weistec Engineering 722.9 Competition Build Package is designed for builders looking to enhance their 7-speed 722.9 transmission. This comprehensive kit provides all the essential components needed for a robust build, with a primary focus on the Weistec 722.9 Clutch Packs. These clutch packs utilize a proprietary Weistec Performance Clutch Material, developed over two years of extensive testing on high-power Weistec vehicles. This advanced material boasts a higher coefficient of friction and superior heat resistance compared to standard materials. Included in this package are new OEM gaskets, seals, and fasteners, ensuring a complete and quality rebuild. The primary benefit of this build package is its ability to significantly increase the torque capacity of the 722.9 transmission, making it suitable for AMG vehicles with enhanced power outputs. The design enhancements contribute to increased durability and longevity under demanding conditions. WARNING: Proper installation and adaptation are crucial for optimal performance and reliability. The use of factory Mercedes transmission fluid, filled according to the specified procedure, is required. Re-adapting the transmission after installation is essential to ensure proper operation. It is strongly recommended that an experienced transmission builder performs the installation to guarantee correct procedures are followed. This build package is specifically designed for various Mercedes-Benz AMG models equipped with the 722.9 transmission, including C63 AMG, CL63 AMG, CLK63 AMG, CLS63 AMG, E63 AMG, ML63 AMG, and S63 AMG. Fitment is confirmed for model years 2007 through 2011 (and later for some models), with V8 6.3L engines. Always use the vehicle selector to confirm exact compatibility.
