Additional Notes

  • Across all five configurations of the MINI Clubman R55 and R55 LCI covered here, the automatic transaxle initial fill capacity is 6 liters, a figure that represents the total fluid volume required when the unit is dry, such as after a complete overhaul or replacement.
  • The service fill capacity of 4.5 liters applies to the Cooper Clubman 88 kW (2006-2010) and 90 kW (2010-2014) variants, reflecting the partial volume exchanged during a routine fluid change rather than a full drain of the transaxle.
  • The Cooper S Clubman 135 kW (2010-2014) specification labels the 4.5-liter service fill value as a filter capacity, distinguishing the fluid volume associated with a filter service from the full initial fill of 6 liters.
  • The Cooper S John Cooper Works 155 kW LCI (2012-2014) lists the 4.5-liter figure without a parenthetical qualifier alongside the 6-liter initial fill, presenting both capacities as separate entries within the same row.
  • A 100,000-mile change interval under normal use conditions is specified for the Cooper Clubman 88 kW (2006-2010), the 90 kW (2010-2014), the Cooper S Clubman 135 kW (2010-2014), and the John Cooper Works 155 kW LCI (2012-2014).
  • The Cooper S Clubman 128 kW (2006-2010) carries no change interval in the specifications, meaning only the initial fill and service fill capacities of 6 liters and 4.5 liters respectively are recorded for that configuration.
  • The gap in output between the 88 kW and 90 kW Cooper Clubman variants does not produce any difference in automatic transaxle fluid specifications, as both share identical initial fill, service fill, and change interval values.
  • The step from the Cooper S Clubman 128 kW to the higher-output 135 kW variant introduces a change interval of 100,000 miles under normal use, a detail absent from the 128 kW specification.
