Austin Maestro

Manual transmission fluid capacity & service interval

Austin Maestro manual transmission fluid capacity ranges from 1,5 to 2 liters. Service intervals require checks every 20000 km or 12 months. The data covers 14 configurations.

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

Additional Notes

  • The Austin Maestro manual transaxle specifications list two distinct fluid capacities across multiple configurations: 1.5 liters and 2 liters. In manual transaxle servicing, a lower figure typically reflects the working fluid level for a top-up or level check, while the higher figure represents the total fill volume associated with a drain-and-refill or overhaul procedure.
  • Both capacity values, 1.5 liters and 2 liters, appear side by side for the same model year ranges across the 1.3, 1.6, and Vanden Plas configurations. This dual-capacity pattern is consistent across all listed variants from 1984 onward, suggesting the transaxle unit used across the Maestro range accommodated more than one fill scenario depending on service type.
  • The 1.3-liter configuration from 1984-1985 lists both the 1.5-liter and 2-liter capacities, while from 1985 onward through 1990 only the 2-liter capacity is listed. This shift in the 1.3 specification after 1985 contrasts with the 1.6, which retains both capacity figures across all of its listed year ranges including 1986-1990.
  • All listed configurations share an identical service interval of 20,000 km or 12 months under normal use conditions, whichever comes first. The time-based threshold of 12 months means fluid condition is evaluated on an annual basis regardless of mileage accumulation, which is relevant for vehicles driven infrequently.
  • The Vanden Plas trim, covering 1984-1986, carries the same dual-capacity and interval specifications as the standard 1.6 configurations for the same period. No distinction in transaxle fluid capacity or check interval separates the Vanden Plas from the base variants in the listed data.
  • The 1.6 configuration has the broadest year span in the specifications, with entries running from 1984 through 1990. Across all three of its sub-ranges, 1984-1985, 1985-1986, and 1986-1990, both the 1.5-liter and 2-liter capacities are consistently listed, making the 1.6 the only engine variant to maintain dual-capacity entries throughout the entire covered period.
