Mercedes-Benz 722.9 Solenoid Shift Valve Assembly

The Mercedes-Benz 722.9 Solenoid Shift Valve Assembly is an 8-solenoid electro-hydraulic pack designed for the 7G-Tronic 722.9 automatic transmission. Housed with an aluminum body and internal electromagnetic coils, these solenoids regulate hydraulic pressure and clutch engagement to control gear shifting, assisted by PWM signals from the transmission control module. The valve-body integrated assembly is intended for direct replacement in compatible 7G-Tronic valve bodies and runs on ATF as the operating medium. This kit supports shifting performance restoration in Mercedes-Benz passenger cars equipped with the 722.9 7-speed transmission, including models such as E-Class, S-Class, C-Class, ML, and CLS, with platforms like W204, W211, W212, W221, and W164. The part is listed under model/part number 722.9 transmission solenoid set (8 pcs typical kit) and is offered by Mercedes-Benz or OEM aftermarket suppliers. When replacing worn solenoids, this set provides the components typically included for EDS and shift pressure control units, aligning with common replacements for the 722.9 valve body solenoid kit and related 7G-Tronic service needs.
