Shift knob loose

Hello,
I own a new to me 2003 Trailblazer. I noticed that the shift knob is a little loose. Does anyone know how to tighten it up? Its an automatic.
Thanks

You can easily tighten up the shift knob. It is just one screw in a hole below the shift knob button (left side). The screw on my 02TB is a small torx screw. (sorry, forgot the size) (torx=star shape)

Thanks, I'll give it a shot.

Had the same problem on an old vehicle I owned. I tried silicon, super-glue, hot glue, etc.... It always came loose. :banghead:
