Has anyone done a Transmission filter and fluid change and caused more issues?

This is all tangential. It's been shown BMW recommends a 100K mile transmission fluid change. They've been doing so for approximately 13 years. As you've previously stated you do not recommend not following the manufacturers recommendations (post 91):

"I have not recommended not following manufacturer's recommendations."

I can assume this is the last we'll hear about this wives tale from you.
