I was driving tonight and i noticed that my c4 was shifting a little late. then when i got home it wouldnt let me move the shifter wouldn't move all the way into park. I pulled the shifter all the way back to 1, then tried to put it in park, but now it wouldnt move past D. I looked at all the linkages underneath to see if it was catching on something, but it all looked ok, I think it must be internal, any ideas? All of your help is greatly appreciated.
