Guys I could really use some help here. I have a 07 limited which had been down for 6 weeks for transmission problems. those problems were went to work pulled in the parking lot and it started acting funny shifting hard in both forward and reverse it was hitting really hard in either direction. I had the collector plate replaced it did nothing I bought a used shifter and now it runs but the key will not come out of the ignition. is it a bad used shifter I bought use? ant ideas guys? I really need help. just turned 70K I have owned it since it had 2K. Any thoughts?
