MINI MINI Roadster, R59 (USA)

Automatic transmission fluid capacity & service interval

MINI Roadster, R59 (USA) automatic transmission fluid capacity ranges from 4,5 to 6 liters. Service intervals occur at 100000 miles. The data covers 3 configurations.

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

Additional Notes

  • Across all three R59 configurations, the automatic transaxle carries an initial fill capacity of 6 liters, which 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 routine fluid changes on the MINI Roadster R59, reflecting the volume that remains in the torque converter and passages during a standard drain procedure rather than a full teardown.
  • The 1.5-liter difference between the 6-liter initial fill and the 4.5-liter service fill on the R59 automatic transaxle is a direct consequence of residual fluid retained in the converter and internal circuits during a service drain.
  • The Cooper (90 kW), Cooper S (135 kW), and John Cooper Works (155 kW) variants all share identical automatic transaxle fluid capacities, meaning output level differences among the three engines do not affect the transmission fluid volume specifications.
  • The John Cooper Works (155 kW) configuration carries a model year start of 2012, placing its introduction one year after the Cooper and Cooper S variants, which both begin in 2011.
  • All three configurations specify a 100,000-mile change interval under normal use conditions, which is a relatively extended drain interval associated with modern sealed or long-life automatic transmission fluid formulations.
  • The 100,000-mile interval is tied specifically to normal use conditions across all R59 automatic transaxle rows, meaning the interval figure in the specifications does not account for any alternative use condition.
