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

But we do get reports of failures, apart from those where the wrong fluid or filter was used, or where there was already a problem. In the past decade, maintenance planning has moved into the science category, while some are still doing things and spending money just because they feel good. I'm all for feeling good, and if it feels good do it, but don't pretend that it is going to extend the transmission life unless there is some rationale other than "that's the way we always did it".

Likewise there are no statistics to demonstrate replacing the fluid increases the risk of transmission failure. No data whatsoever. Just anecdotes.

I'm happy to reconsider my position once you provide supporting data. Until then why would you think my position this is a wives tale would change?
