I think mine binded as well but...
When mine binded it was due to the bracket being under the wrong two bolt holes. I moved the cable bracket and the cable unbound itself. When you are hooking the cable up on the gear selector on the transmission, is the selector all the way forward? If the selector on the transmission is one or 2 gears off and the gear handle inside is in park, you may have issues. If you cant hook the cable up with the selector all the way forward you have shifter cable bracket issues (wrong bolt holes).
Just trying to think my way through any reasons for it to bind.
Not any severe bends in the cable are there?
Good luck,
