722.6 Valve Body 2006-2026, remanufactured and ready to install. Fits the 722.6. Ships fast from the USA.
Shift trouble on a 722.6-equipped Mercedes-Benz or Sprinter looks the same whether the vehicle is an older C-Class or a much newer build on the same transaxle family, and this listing is coded as our widest-coverage valve body for exactly that reason. If the transmission is shifting harsh, hesitating before it drops into gear, or has thrown a stored pressure or solenoid code, this remanufactured valve body spans the broadest range of 722.6 casting revisions we stock.
The valve body is the transaxle's hydraulic switchboard. Line pressure from the pump passes through a bank of precision-machined bores and spool valves, and each passage feeds one clutch pack or band the instant the transmission control module calls for that gear. The shift and pressure control solenoids mount directly to the casting on the electronically controlled 722.6, so a worn bore or a weak solenoid seat shows up as inconsistent pressure control well before the unit actually fails outright.
Scan for codes before you buy, because a worn hydraulic bore and a failing electrical connection on this transaxle can look nearly identical from the driver's seat. Our 722.6 valve body symptoms and testing guide covers the vacuum-test method mechanics use to pin down exactly which bore is leaking pressure, and the 722.6 speed sensor symptoms guide helps rule out a sensor fault before you assume the valve body is at fault.
Because this listing spans the widest range of 722.6 production, it is not a one-casting-fits-everything part: Mercedes-Benz revised the valve body casting and connector design more than once across the C-Class, E-Class, S-Class, M-Class, GL-Class, R-Class and Sprinter lineup, and the Chrysler and Dodge Sprinter share the same transaxle family but not always the same hardware down to the pin. Before ordering, send us your exact model year and VIN, or match the transmission tag and connector pin count on your old unit against the listing photos - that check matters more here than on any narrower year-specific listing, because wide coverage still means matching the right casting to your specific build. If you already know your model year, the year-specific listings in the 722.6/722.9 transmission parts collection may be a tighter match.
Drop the pan and change the fluid and filter alongside the valve body, so wear debris from the old unit doesn't contaminate the replacement. Unplug the solenoid harness before pulling the mounting bolts, and run those bolts back down in the factory crossing sequence so the separator plate and check balls stay seated correctly. Refill with MB 236.14/236.15 approved ATF and check the level at operating temperature through the fill plug, since this transaxle has no dipstick. After reassembly, clear the stored codes and run the adaptive relearn through a mix of light and firmer throttle shifts before judging the new feel. A overhaul kit is worth adding if the unit has other wear beyond the valve body, and the 722.6 master overhaul kit covers the frictions and steels if you are already this deep into the transmission.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It's our widest-coverage listing, built to span multiple casting revisions Mercedes-Benz used across the 722.6's long run. It is still a specific casting, so confirm your transmission tag, connector pin count or VIN with us before ordering rather than assuming any 722.6 valve body bolts straight in.
Harsh, flared or hesitant shifts, slipping between gears or a missing upshift under load, torque converter clutch shudder at cruise, or limp mode with a stored pressure, solenoid or ratio code.
It's meant for buyers who aren't certain which exact casting revision their 722.6 needs, or who want one part number that covers a wide span of builds. If you already know your model year, a year-specific listing can be a tighter match.
MB-approved 236.14 or 236.15 ATF, checked at operating temperature through the fill plug rather than a dipstick.
Fresh fluid and filter at minimum. If you're already into the transmission for other wear, the master overhaul kit covers frictions and steels at the same time.
This is a remanufactured valve body with a 1-year warranty.
