24 00 030 - Removing and installing automatic transmission (GA6HP19Z) N52K
Special tools required:
Important!
After completion of work, check transmission oil level Procedures.
Use only the approved transmission fluid.
Failure to comply with this requirement will result in serious damage to the automatic transmission!
Important!
Aluminium-magnesium materials.
No steel screws/bolts may be used due to the threat of electrochemical corrosion.
A magnesium crankcase requires aluminium screws/bolts exclusively.
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).
