transmission wont go all way into park

gotta say - as it WILL go into park, it has to be something with the shifter/linkage - sadly this is one of those things that is going to be near impossible to diagnose without being there - maybe a few pics would help, but of what exactly, right? My $$ is on some simple little thing that you are overlooking - cable/stop slipped - something fell down into the shifter... you might want to download the installation instructions (if you don't have them) and go through the process as if you were doing a new install.
