Additional Notes

  • The Morris Marina ADO28 manual transmission capacity is 0.85 liter across all four configurations covered in the specifications, spanning both the 1.3 and 1.8 engine variants.
  • A capacity figure of 0.85 liter represents a service fill level, meaning the amount of fluid the transmission holds during normal top-up or refill procedures rather than a full overhaul quantity.
  • The 1.3-liter engine configurations cover two consecutive production periods, 1971-1975 and 1975-1980, both sharing an identical 0.85 liter capacity and the same check interval.
  • The 1.8-liter engine configurations span 1971-1975 and 1975-1978, and both also carry the 0.85 liter capacity figure, indicating no variation between the two displacement options in terms of transmission fluid volume.
  • All four configurations specify a check interval of 10,000 km or 6 months under normal use conditions, whichever comes first, reflecting a time-and-distance dual threshold approach to fluid maintenance scheduling.
  • The 6-month time component of the check interval means that even low-mileage usage does not extend the service window beyond half a year, as calendar time functions as an independent trigger alongside distance.
