MG Midget T, TC/TD/TF Midget

Manual transmission fluid capacity & service interval

MG Midget T, TC/TD/TF Midget manual transmission fluid capacity is 0,7 liter. Service intervals occur every 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 Midget TC, TD, TF, and TF 1500 variants all share a manual transmission fluid capacity of 0.7 liter, a figure consistent with the compact gearboxes found in small British sports cars of the mid-twentieth century.
  • A 0.7-liter capacity is characteristic of a service fill rather than an overhaul fill, meaning the specified volume reflects the amount of fluid needed during a routine drain-and-refill rather than a complete rebuild where additional passages and cavities would require more fluid.
  • The TC Midget, produced from 1945-1950, carries a 10,000 km fluid change interval under normal use conditions, pairing with the 0.7-liter capacity to define a straightforward maintenance cycle for the transmission.
  • The TD Midget, spanning 1950-1953, shares the identical 0.7-liter capacity and 10,000 km change interval under normal use conditions as the TC, indicating no revision to the transmission servicing specification between those two successive models.
  • The TF Midget, covering 1953-1955, and the TF 1500 Midget, covering 1954-1955, both retain the same 0.7-liter capacity and 10,000 km normal-use change interval, showing continuity in transmission service requirements across the TF series despite the TF 1500 representing a displacement upgrade.
  • The 10,000 km change interval specified for all four variants under normal use conditions was a relatively short interval by modern standards, reflecting the lubrication technology and engineering tolerances common to manual transmissions of the 1940s and 1950s.
