Additional Notes

  • Across all MINI Convertible R57 and R57 LCI configurations, the automatic transaxle initial fill capacity is 6 liters, a figure that reflects the total fluid volume required when filling a dry or overhauled unit from empty.
  • The service fill capacity across all listed configurations is 4.5 liters, which is the reduced volume used during a routine fluid change where residual fluid remains in the torque converter and passages after draining.
  • The 1.5-liter difference between the 6-liter initial fill and the 4.5-liter service fill is consistent across every configuration in the R57 and R57 LCI lineup, from the base Cooper to the John Cooper Works variant.
  • The Cooper (88 kW) covering 2008-2010 and the Cooper (90 kW) covering 2010-2015 share identical automatic transaxle specifications, with both the initial fill and service fill capacities unchanged between the two power output variants.
  • The Cooper S (128 kW) from 2008-2010 carries a 100,000-mile change interval under normal use conditions, matching the interval specified for the lower-output Cooper variants in the same generation.
  • The MINI Convertible Cooper S (135 kW) covering 2010-2015 lists the 6-liter initial fill and 4.5-liter service fill capacities but does not carry a change interval entry in the specifications, unlike the other four configurations.
  • The John Cooper Works (155 kW) LCI variant from 2012-2015 shares the same 6-liter initial fill, 4.5-liter service fill, and 100,000-mile normal-use change interval as the base Cooper and Cooper S (128 kW) configurations, despite the higher power output.
  • All five configurations specify normal use conditions, meaning none of the listed capacities or intervals are designated for severe-duty or first-change-only scenarios.
