Honda NSX, NC1 (EU)

Automatic transmission fluid capacity & service interval

Honda NSX, NC1 (EU) automatic transmission fluid capacity ranges from 2,6 liters to 7,5 liters. Service intervals include checks at 20000 km or 12 months, and changes at 30000 km or 60000 km or 36 months. The data covers 4 configurations.

Additional Notes

  • The Honda NSX NC1 (EU) uses a semi-automatic transaxle divided into two distinct fluid circuits: a clutch part and a transmission part, each carrying separate capacity and interval specifications.
  • For the clutch part of the transaxle, the overhaul capacity is 4.5 liters, while the service fill capacity is 2.6 liters. The difference between these two figures reflects the additional fluid volume held in components such as the torque converter or internal passages that are only accessible during a full disassembly.
  • For the transmission part of the transaxle, the overhaul capacity rises to 7.5 liters, with a service fill capacity of 4.6 liters. The larger figures compared to the clutch part indicate a greater internal fluid volume within the gear-carrying section of the unit.
  • Under normal use conditions, both the clutch part and the transmission part share a fluid check interval of 20,000 km or 12 months, whichever comes first, alongside a change interval of 60,000 km or 36 months.
  • Under severe use conditions, the check interval of 20,000 km or 12 months remains unchanged for both parts, but the change interval shortens to 30,000 km with no time-based counterpart specified. The absence of a month-based limit under severe conditions means distance alone governs the change schedule in demanding operating environments.
  • The halving of the change interval from 60,000 km under normal conditions to 30,000 km under severe conditions applies equally to both the clutch part and the transmission part, reflecting the accelerated fluid degradation associated with more demanding use.
