Additional Notes

  • The Mazda B series (EU) B 1600 BNA61 manual transmission holds 1.5 liters of fluid, a figure that applies consistently across both the normal service and initial service intervals.
  • Under normal use conditions, the manual transmission fluid change interval is set at 18,000 km, reflecting a standard maintenance cycle for regular driving demands.
  • An initial service interval of 1,000 km is specified for the B 1600 BNA61, which is a break-in change designed to flush out metal particles and contaminants generated during the early wear-in period of new transmission components.
  • The 1,000 km initial service interval represents a significantly shorter drain period compared to the 18,000 km normal interval, with both intervals sharing the same 1.5-liter fill capacity for the 1971-1976 production years.
