Renaming/Removing part of a filename

All -
New to the community and using the product.
I am looking to set up a rule to rename files by removing part of the filename. I can do it using "replace text" but was wondering if there was a more elegant way to do it.
I have files like these...
My Sample File (1985)_T1.xxx
My Other Sample File (1999)_T3.xxx
My Third Sample File Redone (2005)_T28.xxx
I want to remove the part of the filename between the "_" and the file extension so that it would look like
My Sample File (1985).xxx
My Other Sample File (1999).xxx
My Third Sample File Redone (2005).xxx
Since the "_T##" is part of the filename, I was struggling with how to isolate just that part using attributes - if I even could - to use as part of a rename action.
Thanks for your help
