Mercedes 722.6/722.9 Transmission Pump Body 2004-2018

Mercedes 722.6 / 722.9 Transmission Pump Body (2004–2018)

The Mercedes 722.6 / 722.9 transmission pump body plays a vital role in maintaining proper hydraulic pressure inside the transmission. Designed for vehicles equipped with the 722.6 (5-speed) and 722.9 (7G-Tronic 7-speed) automatic transmissions from 2004 through 2018, this component regulates fluid flow to support clutch engagement, lubrication, and smooth shifting. Because Mercedes transmissions rely on precise hydraulic control, the pump body directly impacts overall performance and reliability.

Over time, wear, scoring, or internal pressure loss can reduce pump efficiency. As a result, drivers may experience slipping, delayed engagement, harsh shifting, or overheating. Replacing the transmission pump body restores correct fluid pressure and improves shift consistency. In addition, confirming whether your vehicle uses the 722.6 or 722.9 transmission ensures proper compatibility, since internal designs differ between the two models. You can verify the transmission type by checking the data plate, VIN information, or service documentation.

This Mercedes transmission pump body works best when installed during a rebuild or major service. For example, pairing it with new seals, clutches, and a refreshed valve body helps maintain balanced hydraulic performance.
