- Oil catch pan
- Clean rags
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Drain Transmission Fluid

Position the oil catch pan underneath the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan and allow the old fluid to drain completely into the catch pan.
Inspect the old fluid for metal shavings or debris.

3. Replace Transmission Filter

Locate the transmission filter, which is typically secured with screws or clips.
Remove the old filter by unscrewing or unclipping it.
Clean the area around the filter mount to ensure no debris enters the transmission.
Install the new transmission filter, ensuring a snug fit.

4. Reinstall Transmission Pan

Clean the transmission pan thoroughly, removing old gasket material.
Apply a new gasket or sealant as per manufacturer specifications.
Reposition the transmission pan and hand-tighten the bolts.
Use a torque wrench to tighten the bolts to the manufacturer's specified torque (consult the service manual for exact value).

5. Refill Transmission Fluid

Reconnect the transmission fluid cooler lines if they were disconnected.
Using a transmission fluid pump, refill the transmission with the appropriate fluid type as specified by BMW.
Start the engine and allow it to idle for a few minutes.
With the engine running, cycle through the gears to circulate the new fluid.

6. Final Checks

Check the transmission fluid level and top off if necessary.
Reconnect the negative battery terminal.
