Solution

1. Verify Manufacturer's Recommendations

Consult the owner's manual or contact a BMW dealership to confirm the specific maintenance schedule for your model.
General recommendation for the BMW X3 F25 is every 60,000 to 100,000 miles, depending on driving conditions.

2. Prepare for Fluid Change

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Raise the vehicle using jack stands if needed for access.

3. Remove the Transmission Fluid Pan

Drain the old transmission fluid by removing the pan bolts.
Carefully lower the pan and allow the fluid to completely drain into a suitable container.
Clean the pan and replace the gasket if necessary.

4. Replace the Transmission Filter

Remove the old filter and install a new transmission filter, ensuring it is seated properly.
Secure the filter according to manufacturer specifications.

5. Reattach the Transmission Fluid Pan

Place the cleaned pan back onto the transmission and install the new gasket.
Tighten the pan bolts to the specified torque (usually around 10-12 Nm for BMW).

6. Refill with New Transmission Fluid

Use a funnel to add new transmission fluid through the fill tube.
Check the owner’s manual for the exact type and quantity of fluid (typically, BMW uses ATF fluid specific to their models).

7. Check Fluid Level

Start the engine and let it run for a few minutes.
Shift through all gears to circulate the fluid.
Check the fluid level again with the dipstick and add more fluid if necessary.
