About this product

2007 sits in the middle of the 722.6's long production run, after Mercedes-Benz's early running changes to the valve body casting and before the updates that came later in the 2010s. If your 2007 C-Class, E-Class, M-Class, GL-Class or R-Class is shifting harsh or hesitant, or has logged a pressure control or shift solenoid fault, this valve body is remanufactured to the casting used in that specific model year.

What the valve body does in a 722.6

The 722.6 uses its valve body as the hydraulic switchboard for the whole transaxle. Pump pressure flows through a bank of precision-bored passages and spool valves, with each passage feeding one clutch pack or band at the moment the transmission control module calls for it. The pressure control and shift solenoids bolted to the body are what actually execute that command, so as a bore wears or a solenoid seat weakens with age, pressure control gets inconsistent well before the unit fails outright - which is why shift quality on a 2007 model with over a decade of service is a common complaint.

Symptoms on this transmission

How to confirm it before you order

Scan for codes before ordering, since a worn bore and a failing electrical connection on this transaxle can produce overlapping symptoms. Our 722.6 shift solenoid symptoms and replacement guide covers how to tell a solenoid-only fault from a hydraulic one, and our 722.6 valve body symptoms and testing guide has the vacuum-test method mechanics use to isolate which bore inside the body is leaking pressure.

Fitment

This valve body is remanufactured to the casting Mercedes-Benz used for the 722.6 in the 2007 model year, which covers the C-Class, E-Class, M-Class, GL-Class and R-Class built that year - 2007 was also the first full model year for the GL-Class on this transaxle. Confirm your transmission tag and connector pin count against the listing photos before ordering, since a mid-cycle casting change can leave two cars built a model year apart with different hardware. The 722.6/722.9 transmission parts collection carries other year ranges if your build date falls outside 2007.

Install notes

Drop the pan and filter at the same time as the valve body so wear debris from the old unit does not circulate into the new one, disconnect the solenoid harness connector before pulling the mounting bolts, and remove those bolts in a crossing pattern so the separator plate and check balls do not shift out of position. 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. Clear the stored codes and run the adaptive relearn through a mix of light and moderate throttle shifts before judging the new shift feel. Inspect the 722.6 pump if line pressure was already marginal before the valve body started acting up, and check the 722.6 clutch module if the transmission was slipping under load before these symptoms began.

722.6 Valve Body 2007: common questions

Does this fit my 2007 Mercedes-Benz?

It's remanufactured to the 722.6 casting Mercedes-Benz used in the 2007 model year, covering the C-Class, E-Class, M-Class, GL-Class and R-Class. Confirm your transmission tag and connector count against the photos, or send your VIN so we can match the exact build.

What symptoms mean I need this part?

Harsh or flared 2-3 and 4-5 shifts, delayed engagement once the fluid is hot, torque converter clutch shudder at cruise, or limp mode with a stored pressure control or solenoid code.

How is a 2007 valve body different from other years?

The 722.6 went through a mid-cycle casting change during its long run, and 2007 falls after the early revisions but before the later 2010s updates - so the hardware can differ from a car built just a couple model years apart.

What fluid does the 722.6 use?

MB-approved 236.14 or 236.15 ATF, checked at operating temperature through the fill plug rather than a dipstick.

What should I replace at the same time?

Fresh fluid and filter at minimum. Check the pump if line pressure was already marginal, and the clutch module if the transmission was slipping under load before the valve body symptoms started.

What's the warranty?

This is a remanufactured valve body with a 1-year warranty.
