Important!
- Do not let skin come in contact with transmission oil and do not inhale fuel vapours.
- Wear protective gloves.
- Ensure adequate ventilation
Important!
Use only the approved transmission oil.
To set the correct level, it is mandatory that the service function "Transmission control unit: oil adjustment" is performed using the diagnosis system.
Failure to comply with this requirement will result in serious damage to the automatic transmission.
Conditions for the oil adjustment:
- Initial condition: Transmission oil temperature 30 °C to 40 °C
- Final condition: Transmission oil temperature 40 °C to 50 °C
Important! Transmission GA8HP70Z with N57 engine from 03/2011!!
Precondition for oil adjustment
- Transmission oil temperature 30°C to maximum 40°C.
(The transmission oil temperature must be maintained. This will increase the oil quantity in the transmission.)
Performing oil-level adjustment:
An oil-level adjustment is necessary for certain fault code entries in the automatic transmission and after repair (e. g. mechatronic replacement, converter replacement, transmission replacement).
- Connect diagnosis and information system.
- Service function (transmission control unit: Oil adjustment) call up
- Carry out oil level check in accordance with instructions
Adding transmission oil:
Stand vehicle on a level surface and secure against rolling off.
Undo oil filler plug (1).
Add automatic transmission fluid according to instructions in the BMW diagnosis system.

It seems that Item #3 is the fill drain plug. It is pretty high up. It would seem that the location of the fill drain plug is NOT indicative of the fill level.
I have a BavarianTechnic cable, but I'm don't think the transmission control unit: oil adjustment is an option on it.
