I did my daughter's '07 328I just shy of 100,000 miles. It now has over 105,000 miles. We could not tell any difference in the transmission shifting before or after the change. It is kind of like changing the engine oil. It's dirty and needs to be changed. You may not necessarily notice any change. There is no reason to run dirty fluid until the trans dies just as there would be no reason to not change the engine oil until the engine dies. Do it!
