Automatic transmission fluid capacity & service interval

MINI Coupe R58 (USA) automatic transmission fluid capacity ranges from 4,5 to 6 liters. Service intervals occur at 100000 miles. Data covers 3 configurations.

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

Additional Notes

  • The MINI Coupe R58 automatic transaxle holds 6 liters at initial fill, which reflects the total fluid volume required when the unit is dry, such as after a complete overhaul or replacement.
  • The service fill capacity across all three configurations is 4.5 liters, representing the amount needed during a routine fluid change when residual fluid remains in the torque converter and passages.
  • The 1.5-liter difference between the 6-liter initial fill and the 4.5-liter service fill is a direct consequence of fluid retained in the torque converter during a drain-and-fill service, which is a common characteristic of automatic transmissions serviced without a full flush.
  • The Cooper (90 kW), Cooper S (135 kW), and John Cooper Works (155 kW) variants all share identical automatic transaxle fluid capacities, despite their differing power outputs.
  • The John Cooper Works (155 kW) configuration carries a start year of 2012, while the Cooper and Cooper S configurations begin in 2011, making the JCW the latest of the three to receive automatic transmission availability in the R58 lineup.
  • All three configurations specify a 100,000-mile change interval under normal use conditions, placing automatic transmission fluid service on a long-interval maintenance schedule relative to many other drivetrain fluids.
