Additional Notes

  • The Commer Light Vans PB automatic transmission fluid capacity is 8.2 liters across all four configurations, which is a figure typical of a full transmission service fill, accounting for fluid held within the torque converter as well as the transmission housing itself.
  • The 1500 Diesel PBR and the 1500 PBC share an identical 8.2-liter capacity, with no difference in automatic transmission fluid volume between the diesel and petrol variants at the 1500 displacement level.
  • The 2500 Diesel PBR and the 2500 PBC likewise carry the same 8.2-liter automatic transmission fluid capacity as the 1500 variants, meaning displacement differences between the two engine families do not affect the transmission fluid volume specification.
  • All four configurations carry a fluid check interval of 8,000 km under normal use conditions, a relatively short inspection cycle that reflects standard maintenance practice for automatic transmissions of the era.
  • The fluid change interval for all four configurations is set at 40,000 km under normal use conditions, placing the drain-and-refill schedule at five times the check interval.
  • The normal use condition applies uniformly across the 1967-1974 model range for all four PB variants, with no separate severe-use interval specified in the available data.
