WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2014 BMW X6, 2013 BMW X6, 2012 BMW X6, 2011 BMW X6, and 2010 BMW X6. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT:

Do not let skin come in contact with transmission oil and do not inhale fuel vapors.
Wear protective gloves.
Ensure adequate ventilation.

IMPORTANT:

After completion of repair work, check TRANSMISSION OIL LEVEL .

Use only the approved transmission oil:

ATF oil Shell L12108* .............. BMW part number 83 22 2 152 426

* Can be substituted by the lifetime oil "ATF -3".............. BMW part number 83 22 2 305 397

Failure to comply with this requirement will result in serious damage to the automatic transmission!

IMPORTANT:

For vehicles with N54/N55 engine up to production date 09/2012, aluminium bolts for the for the securing of the transmission are also installed.

As of production date 09/2012, only steel bolts are installed for the securing of the transmission.

NOTE:

Aluminium screws/bolts must be replaced each time they are released .

Aluminium screws/bolts are permitted with and without color coding (blue).

For reliable identification:

Aluminium screws/bolts are not magnetic .

Jointing torque and angle of rotation must be observed without fail (risk of damage ).

The aluminium bolts can be optionally replaced by steel bolts.
