MG MGA

Manual transmission fluid capacity & service interval

MG MGA manual transmission fluid capacity is 2,55 liters. Service intervals include checking at 5000 km and changing at 10000 km. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The MG MGA manual transmission fluid capacity is 2.55 liters across all four configurations covered in the specifications, spanning the 1500, 1600, 1600 Mk. II, and Twin Cam variants from 1955-1962.
  • A 2.55-liter figure represents a service fill capacity, meaning the amount of fluid required to bring the transmission to its correct operating level during a routine top-up or drain-and-refill procedure.
  • The check interval for all four MGA configurations is set at 5,000 km under normal use conditions, indicating a periodic inspection of fluid level rather than a full fluid replacement at that interval.
  • The change interval across all configurations is 10,000 km under normal use conditions, which is double the check interval, placing a full fluid replacement at every second check point.
  • The MGA 1600 and MGA 1600 Mk. II share identical manual transmission fluid specifications despite being distinct variants, both carrying the same 2.55-liter capacity with 5,000 km check and 10,000 km change intervals.
  • The MGA Twin Cam, which uses a different engine architecture from the pushrod 1500 and 1600 variants, carries the same transmission fluid capacity and service intervals, indicating no differentiation in gearbox servicing requirements between the engine types.
