Claas Lexion 6000

Automatic transmission fluid capacity & service interval

Claas Lexion 6000 uses automatic transmission fluid with a capacity of 17,9 liters. Service intervals occur every 500 hours or 12 months. The data covers 7 configurations.

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

Additional Notes

  • All Claas Lexion 6000 series variants covered here — spanning the 6600, 6700, 6800, and 6900 model designations with the CS84 transmission — share an identical automatic transmission fluid capacity of 17.9 liters when the differential lock is included in the fill.
  • The 17.9-liter figure represents a service fill capacity, meaning the volume required when refilling the transmission during a fluid change rather than a complete overhaul, which would typically account for additional fluid retained in coolers and lines.
  • The CS84 designation refers to the specific transmission unit fitted across the Lexion 6000 range. A single transmission platform across multiple harvester models in the same series commonly results in uniform fluid capacity specifications, as seen here.
  • The TerraTrac variants — available on the 6700, 6800, and 6900 — use the same 17.9-liter transmission capacity as their wheeled counterparts. TerraTrac refers to a tracked undercarriage system, and the shared capacity indicates the transmission assembly itself remains unchanged between the two chassis configurations.
  • The Lexion 6700 and 6800 each include a Tier 3/Stage IIIA emissions variant alongside the standard CS84 configuration. Both emissions-rated variants carry the same 17.9-liter transmission fluid capacity and the same 500-hour or 12-month change interval as the non-Tier 3 versions, indicating the emissions classification affects the engine rather than the transmission assembly.
  • The service interval of 500 hours or 12 months, whichever comes first, applies under normal use conditions across all listed configurations. In agricultural machinery, normal use conditions typically describe standard harvesting operations without the extended stress cycles associated with severe-duty classifications.
  • The dual-trigger interval structure — combining an engine hours threshold with a calendar-based limit — reflects the reality that agricultural equipment may accumulate operating hours unevenly across seasons, making a time-based ceiling relevant even when hourly thresholds are not reached within a given period.
