MINI MINI Countryman, U25 (USA)

Additional Notes

• The MINI Countryman U25 automatic transmission fluid specifications cover three distinct powertrain configurations for the 2024 model year, each carrying different capacity figures.
• The JCW ALL4 (233 kW) and S ALL4 (180 kW) variants share identical fluid capacity ranges, with an initial fill of 4.8-5.5 liters and a service fill of 3.95-4.6 liters under normal use conditions.
• The gap between the initial fill and service fill figures on the JCW ALL4 and S ALL4 reflects the volume of fluid that remains trapped in the torque converter and passages after a drain, meaning a service fill never fully restores the total system volume.
• Both the JCW ALL4 and S ALL4 are noted as transaxle, semi-automatic units, indicating the transmission and drive axle share a common housing, which is a relevant factor when interpreting the stated fluid capacities.
• The SE ALL4 carries an e-transmission designation, distinguishing it from the semi-automatic transaxle found in the combustion-engine variants, and its fluid capacity is listed as a single value of 2.1 liters.
• At 2.1 liters, the SE ALL4 e-transmission holds considerably less fluid than the 4.8-5.5 liter initial fill required by the JCW ALL4 and S ALL4, a difference consistent with the simpler mechanical architecture of electric drive units compared to conventional automatic transaxles.
• All three configurations carry a normal use condition designation, meaning the listed capacities and service parameters apply to standard operating environments rather than severe-duty cycles.
