BMW says the trans fluid is Lifetime. The people who make the trans for BMW (
ZF) say the fluid SHOULD be changed every 80K kms.
IF you change the fluid... only use an approved ZF fluid and I would also replace the trans filter inside the AT pan. You will also need a AT pan gasket and new bolts.
These guys make some nice ZF servicing kits. You just need to know which ZF trans you have(you can look on the AT trans pan area).

New AT fluid will make the trans shift smoother. I would also say you should check your electrical system. A bad alternator or battery can make the trans do strange things. Use a simply Volt/Ohm meter and check the standing battery voltage at the battery. It should be at least 12.8 volts with the engine off, and at least 13.4 volts with the engine running. Also check for AC voltage across the battery with the engine running... you should have less than +1ACvolts. AC at the battery indicates a bad alternator.
