Bentley Continental GTC, 3S

Automatic transmission fluid capacity & service interval

Bentley Continental GTC, 3S uses automatic transmission fluid with a capacity of 11,9 liters. The service interval is 800000 km. The data covers 3 configurations.

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

Additional Notes

  • All three configurations in the Bentley Continental GTC 3S lineup share an identical automatic transmission fluid capacity of 11.9 liters, applying to the V8, W12, and W12 Speed variants alike.
  • The 11.9-liter figure represents a full system fill, the volume associated with a complete transmission overhaul or dry fill rather than a routine drain-and-refill service, which typically recovers a smaller portion of total fluid volume.
  • Each configuration carries a service interval of 800,000 km under normal use conditions, meaning the interval applies to standard driving rather than elevated-stress or high-frequency-cycle operation.
  • An 800,000 km change interval is exceptionally long by automotive standards and reflects a sealed or lifetime-rated transmission design, where the fluid is not expected to require periodic replacement under ordinary operating circumstances.
  • The W12 Speed variant, introduced from 2020, shares the same 11.9-liter capacity and 800,000 km interval as the W12, despite representing a higher-performance configuration within the same generation.
  • All three rows are classified as semi-automatic transmissions, a designation that refers to a dual-clutch or automated manual unit rather than a conventional torque-converter automatic, which is relevant context for understanding why the fluid specification and service interval differ from traditional automatic transmission service schedules.
