  Replace your leaking or deteriorated CVT transmission cooler hose with the factory-correct upper outlet hose for the Nissan Versa and Versa Note. This genuine OEM hose routes transmission fluid from the CVT to the radiator's transmission cooler circuit — keeping CVT fluid at proper operating temperature for reliable, long-term transmission performance. Exact factory fit, correct diameter, correct length.

  ⚠️ Transmission Note — CVT Models Only: This hose fits Versa and Versa Note models equipped with the CVT (Xtronic) automatic transmission only. It does not fit manual transmission models. Always confirm your transmission type with your VIN before ordering.

  Always confirm fitment using your VIN before purchasing.

  Why buy OEM? CVT transmission fluid runs at higher pressures and temperatures than conventional automatic transmission fluid — and the hoses that carry it must maintain flexibility and sealing integrity throughout. Aftermarket transmission cooler hoses for CVT applications frequently use rubber compounds that swell, harden, or seep fluid at the end fittings over time. The genuine Nissan hose is engineered specifically for CVT fluid compatibility and pressure requirements.

  Symptoms this part fixes:

  • Transmission fluid leak near the radiator or cooler line connections
  • Visible weeping, staining, or dripping at the upper cooler hose
  • Low CVT fluid with no obvious external leak
  • CVT slipping, jerking, or overheating — caused by low fluid from a hose leak
  • Hose cracked, hardened, or swollen on inspection
