Automatic transmission fluid capacity & service interval

MINI MINI Cabrio, R52 (EU) automatic transmission fluid has a capacity range of 4,5 to 6 liters. The data covers 2 configurations.

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

TypeSpecifications

  • Capacity 4,5 liter (Service fill)
  • Code: GA6F21AW (Aisin) 6/1
MINI Cabrio One (2003-2008)
  • Use: Normal

Additional Notes

  • Both the Cooper S and One variants share identical automatic transaxle fluid capacities, with a dry fill of 6 liters and a service fill of 4.5 liters across the full 2003-2008 model range.
  • The 6-liter dry fill figure represents the total fluid volume required when filling a completely drained or rebuilt transaxle, such as after an overhaul where the torque converter has also been emptied.
  • The 4.5-liter service fill reflects the reduced volume needed during a routine fluid change, where residual fluid remains in the torque converter and internal passages even after draining.
  • The 1.5-liter difference between dry and service fill capacities on the MINI Cabrio R52 (EU) is consistent with the behavior of automatic transmissions that retain fluid in the torque converter during a standard pan-drop service.
  • All listed configurations are designated for normal use conditions, meaning the specified intervals and capacities apply to standard driving rather than elevated-stress or severe-duty operation.
