I had to replace my shifter last summer due to the leather on the knob getting all worn out. So yes, you'll have to follow pretty much the whole thing to get the shifter assembly replaced. This guide was exactly what I used to get it done. I didn't have to pull the whole center console out. I was able to prop up the front of it enough to get the shifter in and out through the side. Took me about an hour or so.sorry for dragging this up 7 year later.
i need to just change my sifter shaft, i have a 12 that does not have the screw on knob.Do i need to fallow all these steps to just change the shaft?
A new shifter assembly will come with a pin holding it firmly in place. DO NOT REMOVE THIS PIN. You're going to need another pin of some sort (I used a small Phillips screw driver) to line up the holes on the transmission to lock that end in place so it will match up with the shifter when it's installed. You can do this after you remove the old shifter but it will need to be locked in place for the new shifter to work correctly.
I hope that makes sense. Good luck and let us know how it goes!
