Product Overview

What this part is — and why it fails.

The Mercedes-Benz 251 W166-W164-X166 transfer case / coupler comes from the TRANSMESUN 2026 catalog and serves Mercedes-Benz 251 W166/W164/X166. Guangzhou Meishun (TRANSMESUN) is a CE-certified transmission remanufacturing factory in Huadu, Guangzhou, with 20 years in the trade.

Transfer cases and AWD couplers for European and Japanese 4WD platforms — rebuilt with the same 10-stage process as our transmissions, with chain, clutch and actuator wear addressed during the build. Bench-run verified; actuator and chain engagement checked before packing. Fitment for this code is verified in writing against your transmission code or nameplate photo before dispatch — if the code is ambiguous between generations, our engineers will ask before they pack.

Use Cases

Who orders this part, and why.

4WD engagement faults

Coupler and actuator wear shows up as driveline wind-up or delayed engagement — a verified replacement beats actuator rebuild attempts.

Specialist workshops

European 4WD transfer cases are low-volume, high-value stock — we cover the codes others don't.

Distributors

Transfer cases are margin-rich SKUs for importers serving 4WD-heavy markets.
