Mercedes 722.9 Transmission Valve Body
The Mercedes 722.9 (7G-Tronic) valve body fits numerous models from around 2003/2004 to 2016+, across C, E, S, CL, CLS, SL, ML, GL, G, and Sprinter classes, but it’s crucial to verify compatibility by VIN number and transmission variant (VGS1, VGS2, VGS3, VGS4), as the valve body often integrates with the conductor plate (TCM) and has internal variations. Key models include C300/C350, E300/E350/E550, S-Class (W221), ML-Class (W164/W166), and Sprinters.

Crucial Identification Points:
- Transmission Version: There are standard 722.9, 722.9+ (A89 code), and later variants.
- VGS1 vs. VGS2/3/4: Early models (VGS1, roughly pre-2010) require replacing the valve body and conductor plate together, while later ones (VGS2+) can often be separate.
- Part Numbers: Look for specific casting numbers on the valve body itself.
- VIN Verification: Always use your vehicle’s VIN for precise part matching, as variations exist even within the same model year.
How to Check:
- For Parts: Check aftermarket sellers (eBay, FCP Euro) or Mercedes parts sites, providing your VIN.
- For Repair: Consult specialist forums or technicians who can identify the exact version (VGS1, 2, 3, 4) and casting numbers for your transmission.
