GM DEX-CVT

GM DEX‑CVT is a transmission oil specification developed by General Motors for their continuously variable (CVT) automatic gearboxes. Oil that meets DEX‑CVT must provide stable viscosity over a wide temperature range, high thermal resistance, and specific friction characteristics that ensure smooth ratio regulation and prevent excessive wear of the belt and pulley. This approval applies to GM passenger models equipped with CVT, including Chevrolet Cruze, Malibu, Trax and others, as well as some commercial variants where a similar transmission is used. XENUM XA‑TRAN CVT 1 L transmission oil fully complies with DEX‑CVT requirements, delivering long‑lasting protection and optimal performance without the need for additional modifications. When selecting a lubricant under this approval you receive a product that meets GM’s official technical requirements and is suitable for servicing both new and already used CVT systems.
