Mercedes-Benz SLK-Class, R170 (EU)

Manual transmission fluid capacity & service interval

Mercedes-Benz SLK-Class, R170 (EU) manual transmission fluid capacity is 1,5 liters. Service intervals require a check every 30000 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 Mercedes-Benz SLK-Class R170 (EU), the manual transmission fluid capacity is uniformly 1.5 liters, indicating a consistent gearbox unit shared between the SLK 200, SLK 200 Kompressor, and SLK 230 Kompressor variants from 1996-2000.
  • A 1.5-liter capacity is relatively modest for a manual transmission, which is typical of compact, rear-wheel-drive sports car gearboxes where internal volume is kept small to reduce weight and packaging size.
  • The SLK 200 (1996-1997), SLK 200 Kompressor (1996-1997), and SLK 230 Kompressor (1996-1997) all carry a 30,000 km fluid level check interval under normal use conditions.
  • A fluid level check at 30,000 km intervals is a monitoring procedure rather than a full fluid replacement, meaning the transmission is inspected for correct fill level rather than drained and refilled on that schedule.
  • The SLK 200 (1997-2000) row lists only the 1.5-liter capacity under normal use conditions, with no check interval specified in the row data.
  • The distinction between the SLK 200 (1996-1997) and SLK 200 (1997-2000) entries suggests a mid-production specification change occurred around 1997, resulting in two separate rows despite both sharing the same 1.5-liter capacity figure.
  • All four rows are classified under normal use conditions, meaning the listed capacity and interval values apply to standard operating environments rather than severe or demanding service cycles.
