Why is the gearbox of my BMW 8 Series making a strange noise?

I recently purchased a BMW 8 Series and have noticed that the gearbox has been making a strange noise when switching gears. What could be causing this and how can I fix it?

There could be a few different things causing this noise. One possible cause could be worn out gears in the gearbox, which may need to be replaced. Another possibility could be air bubbles in the transmission fluid, which may require a simple fluid flush to fix. I recommend bringing your car to a certified BMW mechanic to diagnose and fix the issue.

I had the same issue with my BMW 8 Series and it turned out to be a faulty gearbox control unit. I suggest checking with a mechanic to see if this could be the problem in your case as well.
