Models Without A Transmission Dipstick
- Ensure transmission fluid temperature is 68-86°F (20-30°C). Use BMW Service Tester (if available) to monitor transmission fluid temperature. Turn on headlights and A/C to increase idle speed. Apply parking brake and start engine. Select each gear and return gear selector to "N" or "P" position.
- Remove fill plug from center (raised area) of oil pan. There is a "stand pipe" behind plug. Some oil will spill from above plug when removed. If oil continues to spill out after plug is removed, transmission is full. Information on adding fluid is not available.
