Man, I'm sorry to hear that. I have an 05 with the same problem, did a little searching around and I found a pretty good solution:

It worked for a lot of people, so get your 3th and 4th gear pressure switches checked out and see if that is whats causing your problems. I replaced mine earlier this week and no change to my vibration sucks...
