Additional Notes
- The MINI Mini F66 (USA) Cooper S (150 kW) carries an initial fill capacity of 4.8–5.5 liters for its transaxle, semi-automatic automatic transmission fluid. An initial fill figure of this range reflects the total volume required when the transmission is dry, such as during an overhaul or complete fluid replacement from an empty state.
- The service fill capacity for the same Cooper S (150 kW) transaxle is specified at a narrower 3.95–4.6 liters. A service fill value lower than the initial fill is typical because residual fluid remains in the torque converter or valve body during a routine drain-and-fill procedure, meaning not all fluid is evacuated.
- The gap between the initial fill range (4.8–5.5 L) and the service fill range (3.95–4.6 L) for the Cooper S (150 kW) transaxle amounts to roughly 0.85–0.95 liters of retained fluid under normal service conditions. Using the initial fill volume during a standard service interval would result in overfilling the unit.
- The specifications for the Cooper S (150 kW) transaxle are tied to a normal use condition, meaning the 3.95–4.6 liter service fill figure applies under standard operating circumstances rather than a severe-duty or first-change-only scenario.
