I'm having a shifter vibration problem that's not related to engine or transmission issues, but rather when the rear suspension hits bumps my shifter vibrates up and down. I've already replaced my stock motor mounts with Prothane Bullet ones and the dealership replaced my trans crossmember with the updated 2008 version. The problem is better, but still exists and did NOT exist when I bought the car. I'm suspecting the driveshaft, carrier bearing or upper control arm. Please let me know if you have one of these you'd like to sell cheap since I'm just throwing parts at the car.
