Hello, I have an '06 Charger and came upon this same problem myself. I began researching it and found this to be the best source of information on it I could find (and I owe you all a great amount of thanks for that). I registered specifically so I could share my rather unorthodox way of 'fixing' the problem in my case. One thing I have to advise, though, is A: do not get your hopes up that it'll be as simple for you as it turned out for me, and B: if I had had a clear head, I would not have tried this and, frankly, don't necessarily suggest you do, but like I said, this worked, and I wanted to add my knowledge to the collective here.
Just as described by everyone one else here the car started normally, no lights no warnings, but the shifter was stuck just a little bit into the movement, maybe an inch. I got on here and other sites and did my research and bemoaned the knowledge I was going to fork out so money and/or some work getting it fixed. But I figured I'd try the release under the change holder first, of course. Surprise surprise it didn't work. Well the car was on and I was pretty frustrated at this point so I tugged on the shifter as hard as I could (again: if I'd have had a clear head I would not do this) and it gave all the way down to drive. Sure I had broke something I drove the car a couple feet, put it in park, then effortlessly back out of park just like normal and drove the car just like normal. This is the first time that venting on something has fixed it for me, but go figure.
Only thing that makes sense to me is my dad suggested maybe it wasn't the pink plastic part at all, maybe a coin had fallen into the console and was wedged in there, I don't know. At any rate, even having fixed it I ordered a replacement aluminum part, because I see now that this is a common problem with my car. Figure I might as well replace it now that I'm armed with the knowledge anyway. Thanks again for all the information here. Hope this helps someone, or at least someone gets a laugh out of it.
