Additional Notes

  • The MG Maestro manual transmission fluid specifications cover the transaxle unit, meaning the gearbox and final drive share a single fluid reservoir rather than being serviced as separate components.
  • A 2-liter fluid capacity applies uniformly across all listed Maestro configurations, from the 1600 variant spanning 1983-1989 to both production periods of the 2.0 EFi.
  • The 2-liter figure represents a service fill capacity, which is the volume required when topping up or refilling a unit already installed in the vehicle, as opposed to a larger overhaul capacity that would account for fluid retained in disassembled components.
  • All listed configurations carry a normal use condition, meaning the 20,000 km or 12-month check interval applies to standard driving circumstances rather than a reduced severe-use schedule.
  • The check interval is expressed as whichever threshold arrives first, so a vehicle covering fewer than 20,000 km within a calendar year would still reach the 12-month trigger before the distance marker.
  • The 2.0 EFi appears across two separate year ranges, 1985-1986 and 1986-1989, both sharing identical capacity and interval specifications of 2 liters and a 20,000 km or 12-month check.
