The top of the shifter. Where the button is that whole piece is very loose. I did manage to tighett it, but still it won't shift.

Look you need to get specific. Let's start by what kind of car you drive. Year make model

And "what" shifter? Part of the transmission? Console? Column? From what you said this almost sounds like a push button?

YOU MEAN THE KNOB ON THE CONSOLE SHIFT LEVER????!??!??!?!?

Is that what?

Right out of the factory service manual..............notice the set screw..............
