Additional Notes

  • Across all listed variants of the Mercedes-Benz SLK-Class R170 (EU), the automatic transmission fluid capacity is uniformly 8 liters, a figure consistent with a service fill rather than a full overhaul capacity, which would typically be higher due to fluid retained in the torque converter and valve body.
  • The SLK 200 appears across two separate production spans, 1996-1997 and 1997-2000, both sharing an identical 8-liter capacity and a 30,000 km check interval under normal use conditions.
  • The SLK 200 Kompressor (1996-1997) and SLK 230 Kompressor (1996-1997) each carry the same 8-liter capacity and 30,000 km check interval as the naturally aspirated SLK 200 of the same period, indicating no capacity differentiation between supercharged and non-supercharged four-cylinder variants in the early production years.
  • The 30,000 km check interval specified for the 1996-2000 variants under normal use conditions refers to a fluid level or condition inspection rather than a full fluid replacement, a distinction common in Mercedes-Benz service schedules of that era.
  • The SLK 32 AMG Kompressor (2001-2004) shares the 8-liter automatic transmission fluid capacity with the earlier variants, though no check interval figure is listed in the specifications for that variant.
