MINI Mini, R56, R56 LCI (USA)

Automatic transmission fluid capacity & service interval

MINI Mini, R56, R56 LCI (USA) automatic transmission fluid capacity ranges from 4,5 to 6 liters. Service intervals occur at 100000 miles. The data covers 6 configurations.

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

Additional Notes

  • Across all listed configurations of the MINI Mini R56 and R56 LCI, the automatic transaxle carries an initial fill capacity of 6 liters. This figure represents the total fluid volume required when the unit is dry, such as after a full overhaul or replacement.
  • The service fill capacity of 4.5 liters applies to the Cooper (88 kW, 2006-2010), Cooper S (128 kW, 2006-2010), Cooper S (135 kW, 2010-2013), and the John Cooper Works (155 kW, 2011-2013). A service fill is lower than the initial fill because residual fluid remains in the torque converter and passages during a routine drain-and-fill procedure.
  • The Cooper (90 kW) LCI covering 2010-2013 lists only the 6-liter initial fill capacity, with no separate service fill value specified.
  • All six configurations share a uniform change interval of 100,000 miles under normal use conditions, indicating the fluid is treated as a long-life fill rather than a frequently serviced item.
  • The Cooper S appears across two overlapping year bands: 2006-2007 and 2007-2010, both rated at 128 kW. Both share identical capacity and interval specifications, reflecting the same transmission application across that production span.
  • The LCI designation marks a mid-cycle refresh of the R56 platform. In the automatic transmission specifications, the LCI Cooper S moves from 128 kW to 135 kW, while the capacity figures and 100,000-mile interval remain unchanged from the pre-LCI Cooper S.
  • The John Cooper Works LCI variant at 155 kW represents the highest output configuration in the listed data. Despite the increased power output compared to the standard Cooper S, the automatic transaxle fluid capacities and change interval are identical to those of the lower-output variants.
