Additional Notes

  • The Nissan Sentra B18 manual transaxle capacity is 2 liters across all listed configurations, a figure consistent with a service fill rather than an overhaul capacity, as overhaul specifications typically account for additional volume within the transmission housing and associated components.
  • Under normal use conditions, the Canadian-market Sentra 2.0 manual transaxle requires a fluid check at 16,000 km or 10 months, whichever comes first, with no fluid change interval specified for that condition.
  • Under severe use conditions, the Canadian-market Sentra 2.0 manual transaxle carries a fluid check interval of 16,000 km or 12 months, paired with a fluid change interval of 32,000 km or 24 months.
  • The severe-use check interval for the Canadian-market Sentra 2.0 is 12 months, which is two months longer than the 10-month check interval specified under normal use, reflecting a difference in how time-based thresholds are applied across the two conditions.
  • The USA-market Sentra 2.0 manual transaxle specifies a fluid check at 10,000 miles or 12 months under both normal and severe use conditions, meaning the distance and time thresholds for the check are identical regardless of operating condition.
  • Under severe use conditions, the USA-market Sentra 2.0 adds a fluid change interval of 20,000 miles or 24 months on top of the standard check schedule, a requirement absent from the normal use specification.
  • The 2019-2021 and 2021-forward Canadian-market Sentra 2.0 configurations share identical capacity and interval figures, with 2 liters, a 16,000 km or 10-month check under normal use, and a 32,000 km or 24-month change under severe use.
  • The same pattern holds for the USA-market entries, where the 2019-2021 and 2021-forward Sentra 2.0 configurations carry the same 2-liter capacity and identical check and change intervals across both normal and severe use conditions.
