When I shift from 1st to second aggressively my 3 makes a squeak and a clunk coming from the trans? Anyone else have this problem? If I let the car chug in first like its going to stall it makes a clunk every time the car bucks. If I drive the car easy it makes no sound at all.

 

I'd bet on a motor mount issue. They had problems back in 2006 and you've got the next generation, but I wouldn't be suprised if they made the same mistake again.
