W124 300E / 300TE 4MATIC Transmission – Mercedes 722.342 (Hydraulic 4-Speed, With Transfer Case)
This is an original Mercedes-Benz 722.342 automatic transmission removed from a 1992 W124 300TE 4MATIC. The donor vehicle carried VIN WDBED90E1NF198553 and was a California-owned wagon its entire life. The car was parted out in 2024, and its most recent documented mileage was 241,000 miles.
Keep your rare and capable Mercedes-Benz W124 4MATIC on the road with this original 722.342 four-speed automatic transmission. Sourced from a 1992 300TE 4MATIC wagon (VIN: WDBED90E1NF198553), this is a complete, tested unit ready to solve your drivetrain needs. This is the specific, integrated transmission and transfer case that powers both the rear and front axles on the first-generation 4MATIC system—a crucial and increasingly difficult-to-find component for these unique sedans and wagons. As a lifelong California vehicle, it has been spared from corrosive winter road salts, making it an excellent core for a rebuild or a direct replacement.
The transmission was a tested, functioning unit at the time it was sold to the current owner, who purchased it at the beginning of 2025. It was never installed and has been stored indoors since.

Why This Transmission Is Hard to Find
The early W124 4MATIC system was produced in low numbers, and the 722.342 is specific to that setup. The integrated transfer case and hydraulic control system were only used from 1990–1993. Many 4MATIC cars were scrapped due to maintenance costs, so clean, tested, complete units like this are becoming rare.
This transmission includes all original accessories and comes from a documented California vehicle that was used until disassembly.
