Additional Notes

  • The MINI Mini R50/R53 (USA) Cooper S (125 kW) with an automatic transaxle carries an initial fill capacity of 6 liters, which reflects the total fluid volume required when the unit is dry, such as after a rebuild or full overhaul.
  • The service fill capacity for the same Cooper S automatic transaxle is 4.5 liters, representing the smaller volume returned during a routine drain-and-fill where residual fluid remains in the torque converter and passages.
  • The 1.5-liter difference between the initial fill and service fill figures is a direct consequence of fluid retained in the converter and valve body during a standard service, making the two values non-interchangeable in practice.
  • Under normal use conditions, the automatic transaxle fluid change interval for the 2004-2006 Cooper S (125 kW) is specified at 100,000 miles.
