Hi Street Rat,
Thank you for the donation.
For bad engine mounts, there would be vibrations when gears are engaged while stopped.
Chassis problem would not cause vibrations. Vehicle might be drifting to either side and unstable.
Transmission seldom vibrates and if they do, it would normlly be via the drive trains.
The problem is more likely to be the drive trains. Check if the CV shaft inner joints have excessive side play. Look out for torn rubber boots.
