I've been having a strong vibration coming from the area where the shifter sits. It only happens on a cold start and lasts until it has been driven about 10 miles. The vibration gets much worse on a left turn and practically disappears on a right turn. I'm guessing it could be cause by a bearing of some sort being that it goes away over time (greasing itself and such.) It's been getting worse over the past few months and I'm hoping its not too hard to fix. Any suggestions on what it might be? Thanks in advance.
