Well it's been a long time since I drove my car, but I don't remember ever feeling this. It shifts just fine through all gears, but when in third gear, if I push up on the shifter and hold it there, it vibrates my hand like something out of the Matrix lol. No noise or anything from the transmission that I can hear, just the lever. Any ideas on what that might be caused from? No I don't drive around pushing full force on my shifter, I just thought I didn't have it all the way in yesterday so I pushed on it a little harder to be sure and was like wtf is that?
Guess it's time to find a Neon transmission now...

mine vibrated when you pushed into the gear beyond the normal location, still shifts like butter.

Somewhat normal.

Mine does that.

When I put the Energy Suspension shifter plate bushings in, it reduced the vibrations a good bit.

i just made a post about this on june 11th. i feel the same thing.
