Solution

1. Preparation

Gather tools and materials:
- 17mm hex socket or wrench
- Transmission fluid specific to BMW specifications (e.g., BMW ATF)
- Clean rags for spills
- Funnel for adding fluid
Safety warning: Ensure the engine is at operating temperature and the vehicle is on a flat surface to get an accurate reading.

2. Access the Transmission Fill Plug

With the vehicle running and at operating temperature, open the hood and secure it.
Locate the transmission fill plug, which is typically found on the side of the transmission case.

3. Check Fluid Level

Carefully remove the fill plug using the 17mm hex socket or wrench.
Allow any excess fluid to drain if it overflows.
Check the fluid level; it should be level with the bottom edge of the fill hole.
If the fluid level is low, proceed to the next step.

4. Add Transmission Fluid

Using a funnel, carefully add the appropriate BMW transmission fluid through the fill hole until it begins to overflow slightly.
Replace the fill plug and tighten it securely to prevent any leaks.

5. Final Inspection

Wipe around the fill plug with a clean rag to remove any spills.
Start the engine and check for any leaks around the fill plug area.
