Sounds like a broken shifter cable. Buy the replacement from gm - it is around $50.

Put the car on a lift or jack stands. Take off the H pipe and the tunnel cover (30+ bolts). Remove the broken cable and put in the new one.

Make sure to use the hold down clip. The shop I took it to forgot and I had to do all the work all over again - about a month later.

Yes either a broken cable or there is a small plastic insulator clip that fits on the cable end that always breaks-----If not the cable or clip---Next would be the " PRNDL " switch that mounts on the side of the trans where the cable connects----The PRNDL switch has to be calibrated to work correctly

Just a heads up I see yours is 04, if it happens on an 03 they changed mid year.make sure you get the rite one there are two diff.ones learned that the hard way.they clip on diff. On the side on the front bracket,closest to the shifter.
