Heres the deal. Rattle coming from middle of dash (guessing it's around where the clutch is at.) It doesn't rattle if I push the clutch in. Second, whenever I put the car into first gear and try to take off at a moderate speed the car jolts and makes a thud thunk sound like the transmission maybe hitting the undercarriage of the car. And it continues to do this in 2nd, sometimes even 3rd. I'm guessing it's due to a bad transmission mount. If it's not a transmission mount what's the next thing you would think it could be. Also keep in mind that the clutch feels like it's started to sleep under heavy acceleration. There you go. Thanks ahead of time.
