why wont the shifter button unlock and go into gear? on 2002 Chevrolet Trailblazer

we are installing rebuilt tranny upon compleation we found that the parking safety lock wont disengage to move from Park. also the truck will only start if we manualy put the shift link into Nutral on the trans. now the cable wont hook up because we cant move the shifter. also wont start in Park.
