722.9 Valve Body 2004-2012, used and ready to install. Fits the 722.9. Ships fast from the USA.
The 722.9, sold under the 7G-Tronic name, was Mercedes-Benz's move to a seven-speed electronically controlled automatic, and it is a different design from the five-speed 722.6 it ran alongside. This used valve body is pulled from the 2004-2012 production run with a W219 reference point, and it fits the 7G-Tronic transaxles built to that casting. If your car is shifting roughly, holding gears too long, or the transmission control unit has logged an adaptation fault, the valve body is the usual starting point on this seven-speed design.
Like its five-speed sibling, the 722.9 valve body routes line pressure through a set of precision bores to apply each clutch pack, with the shift and pressure control solenoids mounted on the body itself carrying the commands from the transmission control unit. The 7G-Tronic adds a layer the 722.6 does not have: a conductor plate design that integrates the VGS control module, so the electronics and the hydraulics are more tightly bundled together on this seven-speed than on the five-speed it replaced.
Mercedes-Benz's own diagnostic bulletin on this transaxle requires reading out the TCU log and EEPROM data before touching adaptation values, and our 722.9 valve body symptoms and testing guide covers that sequence along with the specific wear points behind the shudder and slip complaints above. Our 722.9 common problems and fixes guide is worth a read too, since it is pulled straight from the factory bulletins Mercedes issued for this transaxle rather than generic forum troubleshooting.
This valve body carries a W219 reference and is pulled from the 2004-2012 production window for the 722.9 seven-speed. Confirm your transmission tag and connector count against the listing photos before ordering, since the 7G-Tronic saw internal changes across this span as Mercedes-Benz issued running updates to the VGS control strategy. The 722.6/722.9 transmission parts collection carries other year ranges for this transaxle family if your vehicle falls outside 2004-2012.
Drop the pan and filter before removing the old valve body, disconnect the conductor plate connector carefully since the pins on this seven-speed are not interchangeable with the 722.6's, and remove the mounting bolts evenly so the separator plate stays seated. Refill with MB-approved 236.15 ATF, which is the synthetic fluid specified for 7G-Tronic units built since 2010 and backward-compatible with the earlier years in this range, and check the level at operating temperature. Read out the TCU log before and after the swap, and have a shop with Star Diagnosis or equivalent reset the adaptation counter so the transmission does not relearn against stale data. A 722.9 pump is worth checking if line pressure was already marginal, and a 722.9 TCC solenoid is worth testing separately if torque converter shudder continues after this valve body is installed.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It's pulled from the 722.9 production run with a W219 reference point. Confirm your transmission tag and connector count against the photos, since the 7G-Tronic saw running updates across this span.
No. The 722.9 is the seven-speed 7G-Tronic, a different design from the five-speed 722.6, with a conductor plate that integrates the VGS control module rather than a separate solenoid pack.
Rough or delayed shifts across the gear range, torque converter clutch slip or shudder, or a stored adaptation or pressure control fault code in the TCU log.
Read out the TCU log and EEPROM data first, per Mercedes-Benz's own diagnostic bulletin for this transaxle, before touching adaptation values or assuming the valve body is at fault.
MB-approved 236.15 ATF, the synthetic fluid specified for 7G-Tronic units, checked at operating temperature.
This is a used part backed by a 1-year warranty.
