What are common issues with the BMW 5 Series transmission?

I've noticed some abnormalities in my BMW 5 Series transmission. It's not shifting smoothly and sometimes makes strange noises. What could be causing this and what steps should I take to address it?

It's possible that your transmission fluid needs to be changed, as this can cause shifting issues and noises. I would recommend having it checked and possibly flushed and refilled if necessary. You can also check for any leaks or physical damage to the transmission that may require repairs.
