Under hard acceleration I do not notice it, but driving with hand controls I am not really looking for it. Ladder bar car. Tires have been ruled out. Automatic trans. Solid motor mounts, etc. It just seems excessive you can feel it through the whole car. My trans builder told me never to bump it into nuetral so I wonder if it isnt just the load up through the engine. Any ideas what to check? Some vibration may be normal, just not sure. Galen

Photobucket sucks
