I agree with the broken tranny mount too. If you have a T5, it is more easily noticed, by the shifter movement, than it is on a 700R4.

You should be able to get one at your local AutoZone for cheaper than paying the handling fee from Summit or Jegs. I haven't bought one in a while, but it's likely around $15.

Yup, its most likely your tranny mount. I had to replace mine once already, and I may have cracked this one too. You can get one from Advance or Napa, they run around $10 if I remember correctly.
Really easy to replace too, wont take you much time at all.
