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 held in our climate-controlled warehouse. Each unit went through our six-step inspection — VIN-matching, Shift-Testing through every gear under load, noise and smoke verification, full visual inspection, multi-angle photography, and palletized shipping. 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.
