    Might need a new trans mount unless it's your driveshaft. I'd tackle the trans mount first since it's the cheaper of the two.

    i agree with the trans mount... I just did mine... the rubber splits down the middle and causes vibs, especially when accelerating at highway (or above) speeds....

    This only started happening right after I installed my UMI suspension parts.

    the factory parts are built to reduce driveline vibrations transmited to the body.You removed that feature.
