Additional Notes

  • Across the B1600, B2000, and B2200 Diesel variants, the manual transmission fluid capacity is 1.7 liters, a figure consistent with compact, two-wheel-drive gearbox assemblies of that era.
  • The Mazda B2600 4x4 (1985-1998) carries a notably higher manual transmission fluid capacity of 3.2 liters, nearly double the 1.7-liter figure seen in the other variants. The increased volume reflects the additional internal components associated with a four-wheel-drive transmission assembly.
  • All four variants share an identical check interval of every 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The fluid change interval is set at 45,000 km or 36 months for all listed variants under normal use conditions. A 36-month ceiling means a vehicle covering low annual mileage would still require a fluid change on a time basis before reaching the distance threshold.
  • The B2200 Diesel (1984-1997) shares the same 1.7-liter capacity and service intervals as the petrol-engined B1600 and B2000, indicating the manual transmission unit was common across both fuel types in the two-wheel-drive configuration.
  • The B2000 spans the widest model year range of the two-wheel-drive entries, covering 1984-1994, yet retains the same 1.7-liter capacity and service schedule throughout, suggesting no transmission specification change occurred across that production period.
