Seddon Atkinson Strato
Automatic transmission fluid capacity & service interval
Seddon Atkinson Strato automatic transmission fluid capacity is 18 liters. Service intervals occur every 40000 km or 18 months. The data covers 2 configurations.
The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes
- Both the Strato 32.275L (8x4) and the Strato 32.325L (8x4) share an identical automatic transmission fluid capacity of 18 liters, which is a substantial fill volume consistent with heavy-duty commercial vehicle automatic transmissions designed for high-torque, multi-axle configurations.
- The 18-liter capacity figure represents a service fill rather than a full overhaul quantity, meaning the volume accounts for fluid retained within the torque converter and valve body during a standard drain-and-fill procedure.
- The specified change interval for both configurations is 40,000 km or 18 months under normal use conditions, with whichever threshold is reached first serving as the trigger for service.
- The 18-month time-based component of the interval reflects that fluid degradation occurs through oxidation and moisture absorption over time, independent of distance traveled, which is a relevant factor for vehicles that may accumulate mileage slowly.
- The 40,000 km distance interval is relatively short by modern standards, which is characteristic of automatic transmission service schedules from the mid-1990s through early 2000s, when fluid formulations and transmission designs demanded more frequent maintenance.
- The Sedona Atkinson Strato 32.275L and 32.325L designations differ in their power output figures, yet the identical 18-liter fluid capacity and service interval across both variants indicates a shared transmission unit between the two configurations for the 1994-2001 period.
