This sensor set includes both the Y3/8n1 and Y3/8n2 sensors used on the Mercedes-Benz 722.9 7G-Tronic transmission control unit, addressing a common failure point on this transmission's conductor plate that can cause erratic shifting or transmission fault codes. Supplying both sensors together allows a complete repair of this typical failure mode in one part.

Fitment: Mercedes-Benz models equipped with the 722.9 7G-Tronic automatic transmission, including C-Class, E-Class, S-Class, ML and CLK (W204, W212, W221, W164) across V6 and V8 engine variants.
