Mercedes Transmissions We Cover

Real transmissions from our warehouse, VIN-matched and ready to ship. Mercedes runs its own in-house transmission families — the 722.x and 725.0 automatics, the 724.0 7G-DCT, and the AMG SPEEDSHIFT MCT and DCT variants. Establishing which family your car uses is the single biggest fitment decision on this brand.

7G-Tronic 722.9 7-Speed RWD

C-Class, E-Class, S-Class, CLS, ML, GL (2004–2016). The highest-volume Mercedes automatic in our inventory — conductor plate condition is the check that matters.

9G-Tronic 725.0 9-Speed RWD

C-Class, E-Class, S-Class, GLE, GLC, CLS (2014+). Different bellhousing, TCM and fluid spec from the 722.9 — not a substitute for it.

5G-Tronic 722.6 5-Speed RWD

C-Class, E-Class, S-Class, ML, SLK (1996–2008). Also licensed to Chrysler and Jeep as the NAG1 — same internals, different TCM calibration.

AMG SPEEDSHIFT MCT 7-Speed

E63, S63, CLS63, ML63, GL63, SL63, SL65 AMG (2009–2018). A wet-clutch torque-converter automatic paired with M156 and M157 — not the DCT despite the shared name.

AMG SPEEDSHIFT DCT 7-Speed

SLS AMG, AMG GT (2010+). A true dual-clutch transaxle in longitudinal RWD supercar layout — entirely different hardware from the MCT.

4MATIC Transfer Case

All 4MATIC AWD applications. Chassis-specific and paired to a particular transmission family — a W211 case will not adapt to a W205.

716.6 6-Speed Manual

C-Class, E-Class and SLK manual variants (2000–2014). Limited US production, so enthusiast demand keeps supply tight.

7G-DCT 724.0 Dual-Clutch

CLA, GLA, A-Class non-AMG (2013+). A seven-speed dual-clutch transaxle for the transverse MFA platform — distinct from the AMG SPEEDSHIFT DCT.

AMG SPEEDSHIFT MCT 9-Speed

E63 S, GLE63, GLS63, AMG GT 4-Door (2017+). The current-generation AMG wet-clutch automatic, paired with the M177 twin-turbo V8.

Classic 722.3 / 722.4 4-Speed

300-series, 400-series and classic-era S-Class (1980–1996). Multiple internal calibrations across the production run — match by chassis and year.

G56 6-Speed Manual Diesel

Sprinter and Dodge/Ram Cummins diesel applications. Mercedes-built heavy-duty diesel manual — also listed on our Ram transmissions page.

Plus 722.8 CVT from the A-Class and B-Class, Sprinter diesel automatics, G-Wagen manuals and special-order requests — text us your VIN.

Why Buy a Used Mercedes Transmission from Auto Power Source

Mercedes transmissions are almost entirely in-house designs — the 722.x and 725.0 automatic families are engineered and built by Mercedes rather than sourced from ZF like most BMW and Audi units. That means the 722.9 seven-speed and 725.0 nine-speed have Mercedes-specific TCM calibration, conductor plates and fluid specs that do not cross to other brands even where the case looks similar. The 722.6 5G-Tronic is the one major exception: it was licensed to Chrysler and Jeep as the NAG1, but with completely different TCM calibration. A 722.6 pulled from an E-Class will physically bolt into a Grand Cherokee, and vice versa, but the shift logic and gear ratios will not be right without addressing the TCM.

Every Mercedes transmission we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and stored securely until it ships to you. Certified technicians visually inspect every unit, match it to your VIN and photograph it from multiple angles before shipment. 7G-Tronic 722.9 units get an additional conductor plate inspection at the 13-pin connector; that is the most common failure point on the seven-speed family, and we flag any unit showing leakage or slow gear engagement. Rejected units never reach the buyer.

You pay a fraction of dealer-new pricing for identical Mercedes engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get 30 days from delivery to return for any reason — no restocking fees. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install. Across 100K+ engines and transmissions in stock, we hold a 0% fitment-related return rate.
