HYUNDAI/KIA ATF SP-CVT1

Specification HYUNDAI/KIA ATF SP‑CVT1 is the official approval of transmission fluid for continuously variable (CVT) and conventional automatic gearboxes installed in Hyundai and Kia models with gasoline and diesel engines, including hybrid variants. The specification requires high thermal resistance, stable viscosity over a wide temperature range, and a special friction composition that provides smooth torque transfer, protection against gear pair wear, and prevents converter overheating. ATF SP‑CVT1 meets OEM requirements for protecting the transmission electronic control system and is compatible with the catalyst and DPF, as it contains no sulfate or phosphate additives (SAPS‑free). Although newer approvals SP‑IV and SP‑IV M offer increased stability under high load, they remain backward compatible with the SP‑CVT1 requirements, allowing their use in vehicles designed for this specification. Choosing XENUM oil bearing the HYUNDAI/KIA ATF SP‑CVT1 label guarantees compliance with warranty conditions and extends transmission life.
