Tools Required: Socket set, fluid pump, drain pan, funnel.
Sub-steps:
1. Place the drain pan under the transmission pan.
2. Remove the transmission pan bolts using the socket set and carefully lower the pan.
3. Allow old fluid to drain completely.
4. Replace the transmission filter if applicable.
5. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications (typically around 8 Nm).
6. Use a fluid pump to fill the transmission with new fluid until it reaches the proper level.

3. Software Update

Tools Required: BMW diagnostic tool or ISTA software.
Sub-steps:
1. Connect the BMW diagnostic tool to the OBD-II port.
2. Navigate to the transmission control module settings.
3. Check for available software updates and follow prompts to update the TCM.
