How do you add transmission oil to a 750LI BMW?

To add transmission oil to a BMW 750Li, first ensure the engine is running and the transmission is warmed up. Locate the transmission dipstick or fill plug, typically found near the back of the engine bay. Using a funnel, carefully add the appropriate type of Transmission Fluid through the dipstick tube or fill plug until it reaches the proper level on the dipstick. Always refer to the owner's manual for specific fluid specifications and procedures.
