I have a 2001 impala that won't shift out of park. on 2000 Chevrolet Impala

The car has a column shifter. I have replaced the brake switch,
the shifter, the interlock switch, shifter cable and etc. Shifter works fine if cable is not attached to transmission. I can shift transmission with a wrench, but hook the two together and shifter and transmission will not shift out of park. Please help.
