Scania T series

Automatic transmission fluid capacity & service interval

Scania T series automatic transmission fluid has a capacity range of 20 to 27 liters. Service intervals consist of 20000 km and 45000 km. The data covers 4 configurations.

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

Additional Notes

  • Across all listed configurations of the Scania T series (2005-2006), the automatic transmission carries a service fill capacity of 20 liters, which represents the volume of fluid exchanged during a routine drain-and-fill service without disassembling the unit.
  • The overhaul capacity of 27 liters is 7 liters greater than the service fill figure, reflecting the additional fluid volume held in components such as the torque converter and valve body that are only fully drained when the transmission is completely disassembled.
  • The T-340 Euro 4 and T-380 Euro 4 share identical capacity figures of 20 liters for service fill and 27 liters for overhaul, indicating no difference in transmission fluid volume requirements between the two engine output variants.
  • For construction site use conditions, both the T-340 Euro 4 and T-380 Euro 4 specify a change interval of 20,000 km, a notably shorter interval consistent with the higher thermal and mechanical stress associated with stop-and-go, low-speed, and heavy-load operation.
  • Under distribution use conditions, the same T-340 Euro 4 and T-380 Euro 4 configurations carry a change interval of 45,000 km, more than double the construction site interval, reflecting the comparatively lower stress of regular road-based delivery cycles.
  • The 25,000 km gap between the construction site interval (20,000 km) and the distribution interval (45,000 km) for both variants illustrates how significantly operating environment influences fluid degradation rates in automatic transmissions.
