The 2001 Chevy Cavalier automatic transmission shift linkage is held in place with a swivel nut on each end of the shift linkage. Turn the swivel nuts to the left and the shifting linkage will come off. Reverse the process to install your new shift linkage.

The transmission uses a cable for linkage. If the car has consol shift the cable runs from the shifter to the transaxle. If it is a column shift the cable runs from a lever on the column to the transaxle.
Your shift linkage may have slipped or become loose. Check your linkage.
There is a torx screw on the same side as the button, unscrew it half way and lift up the shift with the boot.
Pull up the shift boot, on the right rear of the shifter body is a button that you press in and hold while you shift into gear.
Your question is too vague. Purchase a service repair manual.
