Automatic transmission fluid capacity & service interval

Honda Prelude automatic transmission fluid capacity ranges from 2,5 to 4,9 liters. Service intervals include 24000 km and 48000 km. The data covers 2 configurations.

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

Additional Notes

  • The Honda Prelude 1600 automatic transaxle holds 4.9 liters at dry fill, a figure that reflects the total fluid volume required when filling a completely drained or rebuilt unit, including the torque converter and all internal passages.
  • The service fill capacity of 2.5 liters is notably lower than the dry fill, representing just over half the total system volume. The remainder stays trapped in the torque converter during a standard drain, which is typical behavior for automatic transaxle service procedures.
  • Under normal use conditions, the Prelude 1600 automatic transaxle carries a fluid change interval of 48,000 km.
  • An initial service interval of 24,000 km applies to the same 1978-1982 Prelude 1600 automatic transaxle, cutting the standard change interval in half for the first fluid replacement. The service fill capacity of 2.5 liters remains the same regardless of whether the change is the initial service or a subsequent normal interval.
