If your transmission feels like it has excessive vibration or movement under normal driving conditions, then this can be an indicator that your factory transmission mount has failed. Over time and miles, your mounts whether they be motor mounts or transmission mounts can be prone to failure. And if you have performed moderate modifications then the added torque can certainly affect the stability of the transmission.
